A press release was issued on June 29, 2004 in Toronto, Ontario and disseminated

On June 29, 2004, Standard & Poor's Rating Services announced that it lowered
the ratings in both the Company's long-term corporate credit rating and its
senior unsecured debt rating by one notch to "BBB-". While the downgrade
reflects concerns surrounding the Company's operating profits over the past 18
months as well as the Company's liquidity position against comparable companies
in the same rating category, it does not trigger changes in the Company's
outstanding debts, save for an increase in the interest rates charged by the
banking syndicate under the Company's termed-out credit facilities.

ROYAL GROUP TECHNOLOGIES LIMITED RESPONDS TO STANDARD & POOR'S RATING ACTION

TORONTO, ONTARIO--(CCNMatthews - Jun 29, 2004)

Today Standard & Poor's Ratings Services ("S&P") issued a press release, stating
that it had lowered the ratings on both Royal Group's long-term corporate credit
rating and its senior unsecured debt rating by one notch to "BBB -". At the same
time, the ratings were removed from CreditWatch, with the outlook being stated
as "negative". Concerns surround the sufficiency of operating profits over the
past 18 months and the company's liquidity position as against comparable
companies in the same rating category.

Royal Group recognizes that while it is facing a challenging environment, it
continues to make progress with the implementation of strategies to turnaround
the Company, and is focused on further increasing profitability and free cash
flow. However, progress with these initiatives has been slowed during the past
few quarters by continuing high raw material costs, a stronger Canadian dollar
and excess capacity.

The lowering of the rating by S&P does not trigger changes in the Company's
outstanding debts, save for an increase in the interest rates charged by the
banking syndicate under the Company's termed-out credit facilities. The
annualized effect of the downgrade on interest expense will be approximately
$1.06 million pre-tax, or less than $0.01 per share after tax.

Royal Group is a manufacturer of innovative, polymer-based home improvement,
consumer and construction products. The Company has extensive vertical
integration, with operations dedicated to provision of materials, machinery,
tooling, real estate and transportation services to its plants producing
finished products. Royal Group's manufacturing facilities are primarily located
throughout North America, with international operations in South America, Europe
and Asia.
