Aug 1 (Reuters) - Futures tied to Canada's main stock

index slipped on Friday, as investors woke up to U.S. President

Donald Trump's new tariff regime that included fresh levies on

Canada and dozens of other countries.

Futures on the S&P/TSX index were down 1% at

1,605.40 points by 06:52 a.m. ET (1052 GMT). The benchmark index

gave back some of its monthly gains in the previous session.

Trump late on Thursday signed an executive order increasing

tariffs on all Canadian goods not covered by the

U.S.-Mexico-Canada trade agreement to 35% from 25%.

He also imposed steep tariffs on imports from dozens of

other trading partners including Brazil, India, Taiwan and

Switzerland, pressing ahead with his plans to reorder the global

economy.

Adding to investors' concerns, Trump sent letters to the

leaders of 17 major pharmaceutical companies outlining how they

should slash U.S. prescription drug prices to match those paid

overseas.

In commodities, gold prices held steady on Friday, while oil

prices were little changed and copper prices stabilised.

In corporate news, Canadian auto parts supplier Magna

International ( MGA ) raised its annual sales forecast and

topped second-quarter estimates, benefiting from its

cost-cutting measures.

Focus will be on the U.S. jobs data, due later in the day.
