TC PipeLines, LP Financial Condition Not Materially Impacted by Enron

Calgary, Alberta - November 29, 2001 - (Nasdaq: TCLPZ) - TC PipeLines, LP (the
Partnership) today announced that based on currently available information, the
recent downgrading of Enron Corp.'s credit ratings and other events involving
Enron, should not have a material adverse impact on the Partnership's financial
condition. However, it is premature to determine with certainty whether and to
what extent the Partnership may be impacted by these events. The Partnership
holds a 30% general partner interest in Northern Border Pipeline Company. The
other 70% general partner interest is held by Northern Border Partners, L.P., a
publicly traded limited partnership, of which Enron controls two of its three
general partners. Northern Border Partners, L.P. is not affiliated with TC
PipeLines, LP.

As detailed in the Partnership's September 30, 2001 Quarterly Report on Form
10-Q, Northern Border Pipeline has a number of relationships with Enron.
Northern Plains Natural Gas Company, a wholly owned subsidiary of Enron,
provides operating and administrative services for Northern Border Pipeline.
Certain of the services are provided through other Enron subsidiaries. The
Partnership believes that Northern Plains will continue to be able to meet its
obligations to provide operational and administrative services under the
existing agreements.

Northern Border Pipeline has an aggregate financial exposure over the next 12
months of approximately $9 million (2.8 percent) of annual revenues under its
firm transportation contracts with Enron North America (ENA), a wholly owned
subsidiary of Enron. The Partnership believes that even if ENA fails to perform
its obligations under the firm transportation contracts it will not have a
material adverse impact on Northern Border Pipeline's financial condition. In
addition, under certain circumstances Northern Border Pipeline has the right to
re-market this capacity to other shippers. If Northern Border Pipeline is unable
to re-market this capacity, the aggregate financial impact from this revenue
shortfall over the next 12 months is approximately $2.7 million to TC PipeLines,
LP.

The Partnership plans to continue to monitor developments at Enron and to
continue to assess the impact these events may have




on Northern Border Pipeline and to take appropriate action to protect the
interests of the Partnership and its unitholders.

TC PipeLines, LP is a publicly held limited partnership. It owns a 30% interest
in Northern Border Pipeline Company, a Texas general partnership, and a 49%
interest in Tuscarora Gas Transmission Company, a Nevada general partnership.
Northern Border Pipeline owns a 1,249-mile United States interstate pipeline
system that transports natural gas from the Montana-Saskatchewan border to
markets in the midwestern United States. Tuscarora owns a 229-mile United States
interstate pipeline system that transports natural gas from Oregon, where it
interconnects with facilities of PG&E National Energy Group, Gas Transmission
Northwest, to northern Nevada. TC PipeLines, LP is managed by its general
partner, TC PipeLines GP, Inc., a wholly owned subsidiary of TransCanada
PipeLines Limited. Subsidiaries of TransCanada also hold common and subordinated
units of the Partnership. Common units of TC PipeLines, LP are quoted on the
