Ottawa’s Big Tech Tax Will Hammer Your Investments, Warns Industry

The federal government is under fire for pushing ahead with a controversial tax on big tech companies—one that business groups say will hurt Canadians more than help them.

In a blunt letter to Prime Minister Mark Carney, some of Canada’s largest business associations—including the Retail Council of Canada and the Canadian Chamber of Commerce—are calling for an immediate halt to the Digital Services Tax (DST), which is set to take effect June 30.

The groups warned earlier this week that the tax will raise prices for consumers, risk major retaliation from the U.S., and threaten the savings and investments of regular Canadians.

“The DST increases prices for Canadian consumers. These costs are real,” the letter states. It also highlights how the tax has already caught the attention of U.S. lawmakers, who are preparing a massive financial response. A measure passed by the U.S. House of Representatives would slap up to a 50% tax on Canadian companies with U.S. operations and holdings—impacting everything from retirement accounts to small businesses.

And it’s not just abstract numbers. The business groups warn that Canadian teachers, municipal workers, and everyday families could see their investments shrink if the government doesn’t pull back.

“Every pension fund, retirement fund, investment account, and deeply interconnected investment funds with American holdings, held by the likes of teachers, municipal workers, elected officials, and regular everyday Canadian families, are at risk,” said the joint letter.

The kicker? Ottawa wants to charge this tax retroactively for the past two and a half years—even as the U.S. is Canada’s largest trading partner.

The business leaders argue that this goes against everything the federal government claims to stand for: affordability, economic security, and stronger cross-border ties. They’re urging the government to pause the tax immediately and let international negotiations play out at the G7 summit, which took place this week.

The DST targets companies earning over €750 million globally and $20 million in Canadian digital services revenue annually — meaning tech giants like Google, Meta, Amazon, Apple, Netflix, Microsoft, TikTok, and others are directly in the crosshairs of the 3% tax.

If the federal government moves ahead with the DST, it could spark a new wave of tariffs and taxes that hurt not just tech giants, but Canadian jobs and wallets too.

The June 13 letter was signed off by the following organizations:

• The Canadian Chamber of Commerce
• Canadian Life and Health Insurance Association
• Retail Council of Canada
• Canadian Venture Capital Association
• Future Borders Coalition
• Canadian Bankers Association

Copies were also sent to Liberal MPs François-Philippe Champagne, Minister of Finance and National Revenue; Dominic LeBlanc, Minister responsible for Canada-U.S. Trade, Intergovernmental Affairs, and One Canadian Economy; and Mélanie Joly, Minister of Industry and Minister responsible for Canada Economic Development for Quebec Regions.

“There is still time to correct course and demonstrate that Canada is serious about strengthening alliances, improving competitiveness, and restoring affordability. The alternative will lead Canada down a very difficult path,” concluded the business groups.
