Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Significant Accounting Policies	Nature of Business and Significant Accounting Policies Nature of Business SiteOne Landscape Supply, Inc. (hereinafter collectively with all its consolidated subsidiaries referred to as the “Company” or individually as “Holdings”) is a wholesale distributor of irrigation supplies, fertilizer and control products (e.g., herbicides), landscape accessories, nursery goods, hardscapes (including pavers, natural stone, and blocks), outdoor lighting, and ice melt products to green industry professionals. The Company also provides value-added consultative services to complement its product offering and to help customers operate and grow their businesses. Substantially all of the Company’s sales are to customers located in the United States of America (“U.S.”), with less than two percent of sales and total assets in Canada for all periods presented. As of June 28, 2020, the Company had over 550 branches. Based on the nature of the Company’s products and customers’ business cycles, historically, sales have been significantly higher in the second and third quarters of each fiscal year. COVID-19 Pandemic As a result of the ongoing novel coronavirus (or COVID-19) pandemic, the Company could experience impacts including, but not limited to, charges from potential adjustments of the carrying amounts of receivables and inventory, goodwill and other asset impairment charges, and deferred tax valuation allowances. There has been no material adverse impact to the Company’s consolidated financial statements for the three and six months ended June 28, 2020; however, the extent to which the COVID-19 pandemic impacts the Company's business, results of operations, and financial condition will depend on future developments, which remain highly uncertain and cannot be predicted, including, but not limited to the duration, spread, and severity, of the COVID-19 pandemic, the effects of the COVID-19 pandemic on the Company's customers, suppliers, vendors, and associates and the remedial actions and stimulus measures adopted by local and federal governments, and to what extent normal economic and operating conditions can resume. Even after the COVID-19 pandemic has subsided, the Company may experience an impact to its business as a result of any economic downturn, recession, or depression that has occurred or may occur in the future. Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as applicable to interim financial reporting. In management’s opinion, the unaudited financial information for the interim periods presented includes all adjustments, consisting of normal recurring accruals necessary for a fair statement of the financial position, results of operations and cash flows. Certain information and disclosures normally included in our annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K filed with SEC for the fiscal year ended December 29, 2019. The interim period unaudited financial results for the three and six-month periods presented are not necessarily indicative of results to be expected for any other interim period or for the entire year. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ materially from these estimates. Fiscal Year The Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to December 31. The fiscal year ending January 3, 2021 includes 53 weeks and the fiscal year ended December 29, 2019 includes 52 weeks. The three months ended June 28, 2020 and June 30, 2019 both include 13 weeks. The six months ended June 28, 2020 and June 30, 2019 both include 26 weeks. Principles of Consolidation The Company’s consolidated financial statements include the assets and liabilities used in operating the Company’s business, including entities in which the Company owns or controls more than 50% of the voting shares. All of the Company’s subsidiaries are wholly owned. All intercompany balances and transactions have been eliminated in consolidation. Significant Accounting Policies Except as updated by the Recently Issued and Adopted Accounting Pronouncements section below, a description of the Company’s significant accounting policies is included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 29, 2019. Recently Issued and Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, “ Leases (Topic 842) ,” amended by subsequent ASUs (collectively “ASC 842”), which supersedes the guidance for recognition, measurement, presentation and disclosures of lease arrangements. The amended standard requires recognition on the balance sheet for all leases with terms longer than 12 months as a lease liability and as a right-of-use (“ROU”) asset. The lease liability is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and the ROU asset is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The Company adopted ASC 842 when it became effective in the first quarter of fiscal year 2019 using a modified transition approach under which prior comparative periods were not adjusted. The Company elected the package of practical expedients, which permitted not reassessing its prior conclusions about lease identification, lease classification, and initial direct costs. In addition, the Company made the election for certain classes of underlying assets to not separate non-lease components from lease components. However, the Company did not elect the lease term hindsight practical expedient. For leases less than 12 months, the Company made an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities as permitted by the guidance. The adoption of the new standard had a material impact on the Company’s Consolidated Balance Sheets, but an immaterial impact on its Consolidated Statements of Operations and Consolidated Statements of Cash Flows. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while the accounting for finance leases remained substantially unchanged. In February 2018, the FASB issued ASU 2018-02, “ Income Statement-Reporting Comprehensive Income (Topic 220) : Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”). The FASB provided ongoing guidance on certain accounting and tax effects of the legislation in the Tax Cuts and Jobs Act (the “2017 Tax Act”), which was enacted in December 2017. ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Act. The amendments in ASU 2018-02 also required certain disclosures about stranded tax effects. The Company adopted ASU 2018-02 when it became effective in the first quarter of fiscal year 2019. The Company has elected to not reclassify stranded tax effects resulting from the 2017 Tax Act. The adoption of ASU 2018-02 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In June 2018, the FASB issued ASU 2018-07, “ Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ” (“ASU 2018-07”) which simplified the accounting for nonemployee share-based payment transactions by expanding the scope of ASC Topic 718, Compensation - Stock Compensation , to include share-based payment transactions for acquiring goods and services from nonemployees. Under the standard, most of the guidance on stock compensation payments to nonemployees was aligned with the requirements for share-based payments granted to employees. The Company adopted ASU 2018-07 when it became effective in the first quarter of fiscal year 2019. The adoption of ASU 2018-07 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-15, “ Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) ” (“ASU 2018-15”) which amends ASC 350-40 to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement (“CCA”) that is a service contract. ASU 2018-15 amended ASC 350 and clarified that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized in a CCA. The ASU did not expand on existing disclosure requirements except to require a description of the nature of hosting arrangements that are service contracts. Entities are permitted to apply either a retrospective or prospective transition approach to adopt the guidance. The Company early adopted the amended guidance on a prospective application basis during the first quarter of fiscal year 2019. The adoption of ASU 2018-15 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In October 2018, the FASB issued ASU 2018-16, “ Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes ” (“ASU 2018-16”). ASU 2018-16 allows for the use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, Derivatives and Hedging . The Company adopted ASU 2018-16 when it became effective in the first quarter of fiscal year 2019. The adoption of ASU 2018-16 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In July 2019, the FASB issued ASU 2019-07, “ Codification Updates to SEC Sections - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization and Miscellaneous Updates (SEC Update) ” (“ASU 2019-07”). ASU 2019-07 clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the SEC’s regulations, thereby eliminating redundancies and making the codification easier to apply. ASU 2019-07 was effective upon issuance and did not have a material impact on the Company’s consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, “ Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments ,” amended by subsequent ASUs (collectively, “ASU 2016-13”), which changes the way companies evaluate credit losses for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model to evaluate impairment, potentially resulting in earlier recognition of allowances for losses. The new standard also requires enhanced disclosures, including the requirement to disclose the information used to track credit quality by year of origination for most financing receivables. The Company adopted the amended guidance when it became effective in the first quarter of fiscal year 2020. The adoption of ASU 2016-13 did not have a material impact on its consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-13, “ Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement ” (“ASU 2018-13”) which changes the fair value measurement disclosure requirements of ASC 820. The ASU adds new disclosure requirements and eliminates and modifies existing disclosure requirements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments in ASU 2018-13 should be applied retrospectively to all periods presented. The Company adopted ASU 2018-13 when it became effective in the first quarter of fiscal year 2020. The adoption of ASU 2018-13 did not have a material impact on its consolidated financial statements and related disclosures. Accounting Pronouncements Issued But Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, “ Simplifying the Accounting for Income Taxes ” (“ASU 2019-12”). The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740, Income Taxes . The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC Topic 740 by clarifying and amending existing guidance. ASU 2019-12 will be effective for the Company commencing in the first quarter of fiscal year 2021 with early adoption permitted. The transition requirements are dependent upon each amendment within this update and will be applied either prospectively or retrospectively. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures. In March 2020, the FASB issued ASU 2020-04, “ Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ” (“ASU 2020-04”). The amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022.

Fair Value Disclosures and Derivative Instruments and Hedging Activities Disclosure [Abstract]
Fair Value Measurement and Interest Rate Swaps	Fair Value Measurement and Interest Rate Swaps Fair value is defined as an exit price, representing an amount that would be received to sell an asset or the amount paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The inputs used to measure fair value are prioritized into the following three-tiered value hierarchy: • Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2: Unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active or inputs, other than quoted prices in active markets, which are observable either directly or indirectly. • Level 3: Unobservable inputs for which there is little or no market data. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The classification of fair value measurement within the hierarchy is based upon the lowest level of input that is significant to the measurement. The Company’s financial instruments consist of cash and cash equivalents, accounts receivables, forward-starting interest rate swap contracts and long-term debt. The variable interest rate on the long-term debt is reflective of current market borrowing rates. As such, the Company has determined that the carrying value of these financial instruments approximates fair value. Interest Rate Swaps The Company is subject to interest rate risk with regard to existing and future issuances of debt. The Company utilizes interest rate swap contracts to reduce its exposure to fluctuations in variable interest rates for future interest payments on existing debt. The Company is party to various forward-starting interest rate swap contracts to convert the variable interest rate to a fixed interest rate on portions of the borrowings under the Term Loan Facility. The following table provides additional details related to the swap contracts: Derivatives designated as hedging instruments Inception Date Effective Date Maturity Date Notional Amount Fixed Interest Rate Type of Hedge Forward-starting interest rate swap 1 June 30, 2017 March 11, 2019 June 11, 2021 $ 58.0 2.1345 % Cash flow Forward-starting interest rate swap 2 June 30, 2017 March 11, 2019 June 11, 2021 116.0 2.1510 % Cash flow Forward-starting interest rate swap 3 December 17, 2018 July 14, 2020 January 14, 2024 34.0 2.9345 % Cash flow Forward-starting interest rate swap 4 December 24, 2018 January 14, 2019 January 14, 2023 50.0 2.7471 % Cash flow Forward-starting interest rate swap 5 December 26, 2018 January 14, 2019 January 14, 2023 90.0 2.7250 % Cash flow Forward-starting interest rate swap 6 May 30, 2019 July 15, 2019 January 14, 2023 70.0 2.1560 % Cash flow The Company recognizes the unrealized gains or unrealized losses as either assets or liabilities at fair value on its Consolidated Balance Sheets. The forward-starting interest rate swap contracts are subject to master netting arrangements. The Company has elected not to offset the fair value of assets with the fair value of liabilities related to these contracts. The following table summarizes the fair value of the derivative instruments and the respective lines in which they were recorded in the Consolidated Balance Sheets as of June 28, 2020 and December 29, 2019 (in millions): Derivative Liabilities June 28, 2020 December 29, 2019 Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedging instruments Interest rate contracts Accrued liabilities $ 5.3 Accrued liabilities $ 2.1 Other long-term liabilities 6.7 Other long-term liabilities 5.3 Total derivatives $ 12.0 $ 7.4 There were no derivative assets for the respective periods presented. For determining the fair value of the interest rate swap contracts, the Company uses significant observable market data or assumptions (Level 2 inputs) that market participants would use in pricing similar assets or liabilities, including assumptions about counterparty risk. The fair value estimates reflect an income approach based on the terms of the interest rate swap contracts and inputs corroborated by observable market data including interest rate curves. The Company recognizes any differences between the variable interest rate payments and the fixed interest rate settlements with the swap counterparties as an adjustment to interest expense over the life of the swaps. The Company has designated these swaps as cash flow hedges and records the estimated fair value of the swaps to Accumulated other comprehensive income (loss) (“AOCI”) on its Consolidated Balance Sheets. For the three and six months ended June 28, 2020 and June 30, 2019, there was no ineffectiveness recognized in earnings. The after-tax amount of unrealized loss on derivative instruments included in Accumulated other comprehensive loss related to the forward-starting interest rate swap contracts maturing and expected to be reclassified to earnings during the next twelve months was $3.9 million as of June 28, 2020. The ultimate amount recognized will vary based on fluctuations of interest rates through the maturity dates. The table below details pre-tax amounts in AOCI and gain (loss) reclassified into income for derivatives designated as cash flow hedges for the three and six months ended June 28, 2020 and June 30, 2019 (in millions): Three Months Ended June 28, 2020 June 30, 2019 Gain (Loss) Recorded in OCI Classification of Gain (Loss) Reclassified from AOCI into Income Gain (Loss) Reclassified from AOCI into Income Gain (Loss) Recorded in OCI Classification of Gain (Loss) Reclassified from AOCI into Income Gain (Loss) Reclassified from AOCI into Income Derivatives in Cash Flow Hedging Relationships Interest rate contracts $ 0.4 Interest and other non-operating expenses, net $ (1.1) $ (5.1) Interest and other non-operating expenses, net $ 0.1 Six Months Ended June 28, 2020 June 30, 2019 Gain (Loss) Recorded in OCI Classification of Gain (Loss) Reclassified from AOCI into Income Gain (Loss) Reclassified from AOCI into Income Gain (Loss) Recorded in OCI Classification of Gain (Loss) Reclassified from AOCI into Income Gain (Loss) Reclassified from AOCI into Income Derivatives in Cash Flow Hedging Relationships Interest rate contracts $ (4.6) Interest and other non-operating expenses, net $ (1.7) $ (8.1) Interest and other non-operating expenses, net $ 0.2

Intangible Assets Intangible assets include customer relationships, and trademarks and other intangibles. Intangible assets with finite useful lives are amortized on an accelerated method or a straight-line method of amortization over their estimated useful lives. An accelerated amortization method reflecting the pattern in which the asset will be consumed is utilized if that pattern can be reliably determined. If that pattern cannot be reliably determined, a straight-line amortization method is used. The Company considers the period of expected cash flows and underlying data used to measure the fair value of the intangible assets when selecting a useful life. During the six months ended June 28, 2020, the Company recorded $22.5 million of intangible assets which related to customer relationships, and trademarks and other, primarily as a result of the acquisitions completed in 2020 as described in Note 3 and adjustments to purchase price allocations related to prior year acquisitions during the allowable measurement period. The customer relationship intangible assets will be amortized over a weighted-average period of approximately 20 years. The trademarks and other intangible assets recorded will be amortized over a weighted-average period of approximately five years.

Leases [Abstract]
Leases	Leases The Company determines if an arrangement is a lease at inception of a contract. The Company leases equipment and real estate including office space, branch locations, and distribution centers under operating leases. Finance lease obligations consist primarily of the Company’s vehicle fleet. Most leases include one or more options to renew, with renewal terms that can extend the lease term from 1 to 5 years or more. The exercise of lease renewal options is at the Company’s sole discretion. Certain leases include options to purchase the leased property. The lease agreements do not contain any material residual value guarantees or material restrictive covenants. Leases with an initial term of 12 months or less are not recorded in the Consolidated Balance Sheets. The Company accounts for each separate lease component of a contract and its associated non-lease components as a single lease component. Variable lease payment amounts that cannot be determined at the commencement of the lease such as increases in lease payments based on changes in index rates or usage, are not included in the ROU assets or lease liabilities and are expensed as incurred and recorded as variable lease expense. ROU assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the net present value of fixed lease payments over the lease term. ROU assets also include any advance lease payments and are adjusted for lease incentives. As most of the Company's operating leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Finance lease agreements generally include an interest rate that is used to determine the present value of future lease payments. Operating fixed lease expense and finance lease amortization expense are recognized on a straight-line basis over the lease term.

Share-based Payment Arrangement [Abstract]
Employee Benefit and Stock Incentive Plans	Employee Benefit and Stock Incentive Plans The Company sponsors a defined contribution benefit plan for substantially all of its employees. Company contributions to the plan are based on a percentage of employee wages. The Company’s contributions to the plan were approximately $2.5 million and $5.2 million for the three and six months ended June 28, 2020, respectively, and $2.1 million and $4.7 million for the three and six months ended June 30, 2019, respectively. The Company’s Omnibus Equity Incentive Plan (the “2016 Plan”), which became effective on April 28, 2016, provides for the grant of awards in the form of stock options, which may be either incentive stock options or non-qualified stock options; stock purchase rights; restricted stock; restricted stock units (“RSUs”); performance shares; performance stock units (“PSUs”); stock appreciation rights (“SARs”); dividend equivalents; deferred stock units (“DSUs”); and other stock-based awards. The Company also has outstanding stock-based awards under its stock incentive plan (“Stock Incentive Plan”) which commenced in May 2014 and terminated upon adoption of the 2016 Plan. However, awards previously granted under the Stock Incentive Plan were unaffected by the termination of the Stock Incentive Plan. At the 2020 Annual Meeting of Stockholders of the Company on May 13, 2020 (the “Effective Date”), the Company’s stockholders approved the Company’s 2020 Omnibus Equity Incentive Plan (the “2020 Plan”), which replaced the 2016 Plan. The 2020 Plan reserves 2,155,280 shares of the Company’s common stock for issuance under the 2020 Plan, consisting of 1,600,000 new shares plus 555,280 shares that were previously authorized for issuance under the 2016 Plan and that, as of the Effective Date, were not subject to outstanding awards. No further grants of awards will be made under the 2016 Plan; however, outstanding awards granted under the 2016 Plan will remain outstanding and will continue to be administered in accordance with the terms of the 2016 Plan and the applicable award agreements. Any shares covered by an award, or any portion thereof, granted under the 2020 Plan, the 2016 Plan, or Stock Incentive Plan that terminates, is forfeited, is repurchased, expires, or lapses for any reason will again be available for the grant of awards, subject to certain exceptions. Additionally, any shares tendered or withheld to satisfy the grant or exercise price or tax withholding obligations pursuant to any award under the 2020 Plan, the 2016 Plan, or the Stock Incentive Plan will again be available for issuance. The aggregate number of shares which may be issued under the 2020 Plan is 2,155,280 shares, of which 2,153,901 remain available as of June 28, 2020. The stock options and RSUs granted to employees vest over a four ten three The fair value of each stock option is estimated on the date of grant using the Black-Scholes options pricing model. The DSUs, RSUs, and PSUs have grant date fair values equal to the fair market value of the underlying stock on the date of grant. Share-based compensation expense is recognized in the financial statements based upon fair value on the date of grant. The compensation cost for stock options and RSUs is recognized on a straight-line basis over the requisite vesting period.

The ABL Facility is secured by a first lien on the inventory and receivables of the Borrowers. The ABL Facility is guaranteed by SiteOne Landscape Supply Bidco, Inc. (“Bidco”), an indirect wholly-owned subsidiary of the Company, and each direct and indirect wholly-owned U.S. restricted subsidiary of Landscape. The availability under the ABL Facility was $187.3 million and $263.4 million as of June 28, 2020 and December 29, 2019, respectively. Availability is determined using borrowing base calculations of eligible inventory and receivable balances less the current outstanding ABL Facility and letters of credit balances. On February 1, 2019, the Company entered into the Sixth Amendment to Credit Agreement, to among other things, (i) extend the termination date to February 1, 2024, (ii) increase the aggregate principal amount of the commitments under the ABL Credit Agreement to $375.0 million pursuant to an increase via use of the existing “incremental” provisions of the ABL Credit Agreement, and (iii) amend certain terms of the ABL Credit Agreement and Guarantee and Collateral Agreement. The interest rate on the ABL Facility is LIBOR plus an applicable margin ranging from 1.25% to 1.75% or an alternate base rate for U.S. denominated borrowings plus an applicable margin ranging from 0.25% to 0.75%. The interest rate on outstanding balances was 1.68% as of June 28, 2020 and was 3.21% as of December 29, 2019, respectively. Additionally, the Borrowers paid a commitment fee of 0.25% and 0.25% on the unfunded amount as of June 28, 2020 and December 29, 2019, respectively. The ABL Facility is subject to mandatory prepayments if the outstanding loans and letters of credit exceed either the aggregate revolving commitments or the current borrowing base, in an amount equal to such excess. Additionally, the ABL Facility is subject to various covenants requiring minimum financial ratios and additional borrowings may be limited by these financial ratios. Failure to meet any of these covenants could result in an event of default under these agreements. If an event of default occurs the lenders could elect to declare all amounts outstanding under these agreements to be immediately due and payable, enforce their interest in collateral pledged under the agreement, or restrict the Borrowers’ ability to obtain additional borrowings under these agreements. The ABL Facility contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants consist of the following: fundamental changes, dividends and distributions, acquisitions, collateral, payments and modifications of restricted indebtedness, negative pledge clauses, changes in line of business, currency, commodity and other hedging transactions, transactions with affiliates, investments, limitations on indebtedness, and liens. The negative covenants are subject to the customary exceptions and also permit the payment of dividends and distributions, investments, permitted acquisitions and payments or redemptions of junior indebtedness upon satisfaction of a payment condition. As of June 28, 2020, the Company is in compliance with all of the ABL Facility covenants. Term Loan Facility The Borrowers entered into a syndicated senior term loan facility dated April 29, 2016, which was amended on November 23, 2016, May 24, 2017, December 12, 2017 and August 14, 2018 (the “Term Loan Facility”). The Term Loan Facility is guaranteed by Bidco and each direct and indirect wholly-owned U.S. restricted subsidiary of Landscape. The Term Loan Facility has a first lien on Property and equipment, Intangibles, and equity interests of Landscape, and a second lien on ABL Facility assets. In connection with the amendment on August 14, 2018, the final maturity date of the Term Loan Facility was extended to October 29, 2024. Term Loan Facility Amendments On August 14, 2018, the Company amended the Term Loan Facility (the “Fourth Amendment”) to, among other things, (i) add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche E Term Loans”) in an aggregate principal amount of $347.4 million and (ii) increase the aggregate principal amount of Tranche E Term Loans under the Term Loan Facility to $447.4 million. Proceeds of the Tranche E Term Loans were used to, among other things, (i) repay in full the Tranche D Term Loans and (ii) repay approximately $96.8 million of borrowings outstanding under the ABL Facility. The Tranche E Term Loans bear interest, at Landscape Holding’s option, at either (i) an adjusted LIBOR rate (as defined in the Term Loan Facility) plus an applicable margin equal to 2.75% or (ii) an alternative base rate plus an applicable margin equal to 1.75%. The other terms of the Tranche E Term Loans are generally the same as the terms applicable to the previously existing term loans under the Term Loan Facility, provided that certain terms of the Term Loan Facility were modified by the Fourth Amendment. The interest rate on the outstanding balance was 3.75% at June 28, 2020. The Term Loan Facility contains customary representations and warranties and customary affirmative and negative covenants, which fully restrict retained earnings of the Borrowers. The negative covenants are limited to the following: limitations on indebtedness, restricted payments, restrictive agreements, sales of assets and subsidiary stock, transactions with affiliates, liens, fundamental changes, amendments, lines of business, and limitations on certain actions of the parent borrower. The negative covenants are subject to the customary exceptions. The Term Loan Facility is payable in consecutive quarterly installments equal to 0.25% of the aggregate initial principal amount of the Tranche E Term Loans until the maturity date. In addition, the Term Loan Facility is subject to annual mandatory prepayments in an amount equal to 50% of excess cash flow, as defined in the Term Loan Credit Agreement for the applicable fiscal year if 50% of excess cash flow exceeds $10.0 million and the secured leverage ratio is greater than 3.00 to 1.00. As of June 28, 2020, the Company is in compliance with all of the Term Loan Facility covenants. During the three and six months ended June 28, 2020, the Company incurred total interest expense of $7.6 million and $15.3 million, respectively. Of this total, $6.8 million and $13.7 million related to interest on the ABL Facility and the Term Loan Facility for the three and six months ended June 28, 2020, respectively. The debt issuance costs and discounts are amortized as interest expense over the life of the debt. Amortization expense related to debt issuance costs and discounts were $0.5 million and $1.0 million for the three and six months ended June 28, 2020, respectively. The remaining $0.3 million and $0.6 million of interest was primarily related to interest attributable to finance leases for the three and six months ended June 28, 2020, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe Company’s effective tax rate was approximately 16.4% for the six months ended June 28, 2020 and 19.3% for the six months ended June 30, 2019. The decrease in the effective rate was due primarily to an increase in the amount of excess tax benefits from stock-based compensation recognized as a component of Income tax expense in the Company’s Consolidated Statements of Operations. The Company recognized excess tax benefits of $6.7 million for the six months ended June 28, 2020 and $3.7 million for the six months ended June 30, 2019. The Company’s effective tax rate differs from its statutory rate based on a variety of factors, including overall profitability, the geographical mix of income taxes, and the related tax rates in the jurisdictions in which it operates.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings (Loss) Per Share The Company computes basic earnings (loss) per share (“EPS”) by dividing Net income (loss) attributable to common shares by the weighted average number of common shares outstanding for the period. The Company includes vested DSUs in the basic weighted average number of common shares calculation. The Company’s computation of diluted EPS reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock, which include in-the-money outstanding stock options and RSUs. PSUs are excluded from the calculation of dilutive potential common shares until the performance conditions have been achieved. Using the treasury stock method, the effect of dilutive securities includes the additional shares of common stock that would have been outstanding based on the assumption that these potentially dilutive securities had been issued. The calculation of the effect of dilutive securities excludes any derived excess tax benefits or deficiencies from assumed future proceeds. RSUs and stock options with exercise prices that are higher than the average market prices of our common stock for the periods presented are excluded from the diluted EPS calculation because the effect is anti-dilutive. For the three and six months ended June 28, 2020 and June 30, 2019, the assumed exercises of a portion of the Company’s employee stock options and RSUs were anti-dilutive and, therefore, the following potential shares of common stock were not included in the diluted earnings (loss) per common share calculation: Three Months Ended Six Months Ended June 28, 2020 June 30, 2019 June 28, 2020 June 30, 2019 Weighted average potential common shares excluded because anti-dilutive Employee stock options and RSUs 216,595 595,845 173,188 538,117 Certain of the Company’s employee stock options, RSUs, and DSUs were dilutive and resulted in additional potential common shares included in the Company’s calculation of diluted earnings per common share of 1,163,121 and 1,223,002 for the three and six months ended June 28, 2020, and 1,588,512 and 1,575,298 for the three and six months ended June 30, 2019, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as applicable to interim financial reporting. In management’s opinion, the unaudited financial information for the interim periods presented includes all adjustments, consisting of normal recurring accruals necessary for a fair statement of the financial position, results of operations and cash flows. Certain information and disclosures normally included in our annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K filed with SEC for the fiscal year ended December 29, 2019. The interim period unaudited financial results for the three and six-month periods presented are not necessarily indicative of results to be expected for any other interim period or for the entire year.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ materially from these estimates.
Fiscal Year	Fiscal YearThe Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to December 31. The fiscal year ending January 3, 2021 includes 53 weeks and the fiscal year ended December 29, 2019 includes 52 weeks. The three months ended June 28, 2020 and June 30, 2019 both include 13 weeks. The six months ended June 28, 2020 and June 30, 2019 both include 26 weeks.
Principles of Consolidation	Principles of Consolidation
Recently Issued and Adopted Accounting Pronouncements and Accounting Pronouncements Issued But Not Yet Adopted	Recently Issued and Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, “ Leases (Topic 842) ,” amended by subsequent ASUs (collectively “ASC 842”), which supersedes the guidance for recognition, measurement, presentation and disclosures of lease arrangements. The amended standard requires recognition on the balance sheet for all leases with terms longer than 12 months as a lease liability and as a right-of-use (“ROU”) asset. The lease liability is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and the ROU asset is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The Company adopted ASC 842 when it became effective in the first quarter of fiscal year 2019 using a modified transition approach under which prior comparative periods were not adjusted. The Company elected the package of practical expedients, which permitted not reassessing its prior conclusions about lease identification, lease classification, and initial direct costs. In addition, the Company made the election for certain classes of underlying assets to not separate non-lease components from lease components. However, the Company did not elect the lease term hindsight practical expedient. For leases less than 12 months, the Company made an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities as permitted by the guidance. The adoption of the new standard had a material impact on the Company’s Consolidated Balance Sheets, but an immaterial impact on its Consolidated Statements of Operations and Consolidated Statements of Cash Flows. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while the accounting for finance leases remained substantially unchanged. In February 2018, the FASB issued ASU 2018-02, “ Income Statement-Reporting Comprehensive Income (Topic 220) : Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”). The FASB provided ongoing guidance on certain accounting and tax effects of the legislation in the Tax Cuts and Jobs Act (the “2017 Tax Act”), which was enacted in December 2017. ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Act. The amendments in ASU 2018-02 also required certain disclosures about stranded tax effects. The Company adopted ASU 2018-02 when it became effective in the first quarter of fiscal year 2019. The Company has elected to not reclassify stranded tax effects resulting from the 2017 Tax Act. The adoption of ASU 2018-02 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In June 2018, the FASB issued ASU 2018-07, “ Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ” (“ASU 2018-07”) which simplified the accounting for nonemployee share-based payment transactions by expanding the scope of ASC Topic 718, Compensation - Stock Compensation , to include share-based payment transactions for acquiring goods and services from nonemployees. Under the standard, most of the guidance on stock compensation payments to nonemployees was aligned with the requirements for share-based payments granted to employees. The Company adopted ASU 2018-07 when it became effective in the first quarter of fiscal year 2019. The adoption of ASU 2018-07 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-15, “ Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) ” (“ASU 2018-15”) which amends ASC 350-40 to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement (“CCA”) that is a service contract. ASU 2018-15 amended ASC 350 and clarified that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized in a CCA. The ASU did not expand on existing disclosure requirements except to require a description of the nature of hosting arrangements that are service contracts. Entities are permitted to apply either a retrospective or prospective transition approach to adopt the guidance. The Company early adopted the amended guidance on a prospective application basis during the first quarter of fiscal year 2019. The adoption of ASU 2018-15 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In October 2018, the FASB issued ASU 2018-16, “ Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes ” (“ASU 2018-16”). ASU 2018-16 allows for the use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, Derivatives and Hedging . The Company adopted ASU 2018-16 when it became effective in the first quarter of fiscal year 2019. The adoption of ASU 2018-16 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In July 2019, the FASB issued ASU 2019-07, “ Codification Updates to SEC Sections - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization and Miscellaneous Updates (SEC Update) ” (“ASU 2019-07”). ASU 2019-07 clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the SEC’s regulations, thereby eliminating redundancies and making the codification easier to apply. ASU 2019-07 was effective upon issuance and did not have a material impact on the Company’s consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, “ Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments ,” amended by subsequent ASUs (collectively, “ASU 2016-13”), which changes the way companies evaluate credit losses for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model to evaluate impairment, potentially resulting in earlier recognition of allowances for losses. The new standard also requires enhanced disclosures, including the requirement to disclose the information used to track credit quality by year of origination for most financing receivables. The Company adopted the amended guidance when it became effective in the first quarter of fiscal year 2020. The adoption of ASU 2016-13 did not have a material impact on its consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-13, “ Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement ” (“ASU 2018-13”) which changes the fair value measurement disclosure requirements of ASC 820. The ASU adds new disclosure requirements and eliminates and modifies existing disclosure requirements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments in ASU 2018-13 should be applied retrospectively to all periods presented. The Company adopted ASU 2018-13 when it became effective in the first quarter of fiscal year 2020. The adoption of ASU 2018-13 did not have a material impact on its consolidated financial statements and related disclosures. Accounting Pronouncements Issued But Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, “ Simplifying the Accounting for Income Taxes ” (“ASU 2019-12”). The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740, Income Taxes . The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC Topic 740 by clarifying and amending existing guidance. ASU 2019-12 will be effective for the Company commencing in the first quarter of fiscal year 2021 with early adoption permitted. The transition requirements are dependent upon each amendment within this update and will be applied either prospectively or retrospectively. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures. In March 2020, the FASB issued ASU 2020-04, “ Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ” (“ASU 2020-04”). The amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.
