ROYAL GROUP TECHNOLOGIES LIMITED RESPONDS TO DBRS' RATING ACTION

TORONTO, ONTARIO -- (CCNMatthews - Jul 7, 2004) -- Yesterday, Dominion Bond
Ratings Services ("DBRS") issued a press release stating that it had lowered the
rating on Royal Group Technology Limited's (RYG:TSX, NYSE) Medium-Term Notes by
one notch to "BBB". At the same time, the trend was changed to Stable, from
Negative. Concerns cited surround the decline in profitability in recent years.

As stated in its response to the rating action by Standard & Poor's Ratings
Service ("S&P") last week, Royal Group recognizes that it is facing a
challenging environment and that its progress with turn-around initiatives has
been slowed during the past few quarters by continuing high raw material costs,
a stronger Canadian dollar and excess capacity. However, Royal continues to make
progress with the implementation of its turn-around strategies, and its focus on
further increasing profitability and free cash flow.

DBRS noted in their press release that Royal Group's BBB rating and stable trend
is supported by a "reasonable financial risk profile, as free cash flow
generation has benefited from sharply reduced capital spending and working
capital restraint in recent years." Royal remains committed to these strategies.

The lowering of the rating by DBRS will not have any impact on the Company's
interest expense beyond that caused by the rating action of S&P last week, nor
will it trigger any changes in the Company's outstanding debts.
