One of Canada含羞草研究社檚 most influential business lobby groups is warning Ottawa about damage to the relationship with the United States after the Biden administration escalated efforts to halt the federal government含羞草研究社檚 tax on large foreign digital services companies.

The Business Council of Canada called for the digital services tax to be revoked after the Office of the United States Trade Representative requested dispute settlement consultations under the Canada-U.S.-Mexico trade agreement.

In a Sept. 9 letter to Finance Minister Chrystia Freeland and International Trade Minister Mary Ng, Goldy Hyder, the council含羞草研究社檚 president and CEO, said retaliatory measures by the U.S. would be harmful to Canadian families, businesses and the economy, while also negating any projected tax revenues.

Hyder cautioned the tax could also be destructive to Canada含羞草研究社檚 relationship with the U.S. ahead of the review of the trade agreement in 2026.

含羞草研究社淚n successive meetings with senior U.S. officials, we have been repeatedly told that if Canada含羞草研究社檚 unilateral DST remains in place it will imperil the upcoming mandatory review of the CUSMA,含羞草研究社� Hyder wrote.

Americans have been critical of the three per cent levy on foreign tech giants that generate revenue from Canadian users. It means the companies will have to pay taxes on that revenue in Canada.

U.S. Trade Representative Katherine Tai, after requesting dispute consultations in August, called the tax discriminatory and said it is inconsistent with Canada含羞草研究社檚 commitments not to treat U.S. businesses less favourably than Canadian ones.

If the two countries are unable to resolve America含羞草研究社檚 concerns within 75 days, the U.S. may request a dispute settlement panel to examine the issue.

Ng and Freeland have remained steadfast behind the tax. They said last month that consultations under the trade agreement含羞草研究社檚 dispute mechanism will demonstrate Canada is meeting its obligations.

Hyder said Ottawa含羞草研究社檚 strategy will neither address nor assuage U.S. concerns. Instead it will risk undermining the trade agreement and 含羞草研究社渙ur most important trade and investment partnership,含羞草研究社� he said.

The digital tax was part of the Liberal election platform during the 2019 campaign. Both the Conservatives and New Democrats proposed similar levies.

The Liberal government, however, delayed its implementation in order to give more time to global efforts to establish a broader, multinational taxation plan.

But after significant delays to that process at the Organization for Economic Co-operation and Development, Canada went ahead with its own tax.

The Canadian ministers have said the preference has always been a multilateral agreement.

Greta Peisch, the former general counsel for the Office of the U.S. Trade Representative, said concerns around Canada含羞草研究社檚 approach to the tax have been raised for a long time.

含羞草研究社淚 think the United States has been clear about how serious it is,含羞草研究社� said Peisch, a partner at Wiley Rein in Washington, D.C.

含羞草研究社淭he argument is not that you can含羞草研究社檛 have a DST, it含羞草研究社檚 just that it should be neutral and not be inconsistent with our trade agreement.含羞草研究社�

Peisch said the issue is around global revenue. Canada含羞草研究社檚 tax applies to foreign and Canadian digital services providers that earn total annual revenue from all sources of 750 million euros or more, and annual Canadian revenue more than $20 million a year.

Peisch explained American含羞草研究社檚 issue with the tax: if two companies provide the same service and have the same revenue from people in Canada, the foreign company will be treated differently.

含羞草研究社淲e have commitments in our trade agreements not to discriminate based on national origin among the trade agreement partners, that would be inconsistent with our trade obligations,含羞草研究社� Peisch said.

The digital services tax has drawn opposition from trade associations and business groups on both sides of the international border.

Last month, Google announced it will implement a 2.5 per cent surcharge for ads displayed in Canada starting in October. Groups representing Canadian advertisers have warned other companies could follow the tech giant含羞草研究社檚 lead.
