5 things to know if Canada hits back against Trump tariffs

U.S. President Donald Trump has threatened to impose a punishing 25 per cent tariff on everything imported to the U.S. from Canada. In return, the Canadian government says it will impose retaliatory tariffs of its own. Here's what would happen if Canada takes that route.

Retaliatory tariffs risk ultimately being paid for by Canadians, not the U.S.

United States President Donald Trump has threatened to impose a punishing 25 per cent tariff on everything imported to the U.S. from Canada. In return, the Canadian government says it would impose retaliatory tariffs of its own on U.S. goods entering Canada.

"Our job is to make sure we're ready for every scenario," Finance Minister Dominic Leblanc told CBC News on Monday when it appeared Canada would be spared tariffs in the short-term.

Trump said Monday night that those tariffs could be coming Feb. 1. Here's what would happen if Canada takes a retaliatory route.

Liberal cabinet strategizes over looming tariff threat

U.S. President Donald Trump hasn’t imposed tariffs on Canada — yet, but the Liberal cabinet met to strategize and Ontario’s premier threatened to pull American booze from the shelves.

How does Canada impose tariffs?

Canada has a complicated system of tariffs — essentially a tax on imports from around the world. There are so many different tariffs for different goods from different countries that the manual that the Canada Border Services Agency (CBSA) uses to calculate tariffs is more than 1,400 pages.

Under Section 53 the Customs Tariff act, cabinet is empowered to adopt an order in council to impose tariffs or change tariff rates. Generally, a change is proposed by the finance and foreign affairs ministers and is subject to approval by the Treasury Board cabinet committee. This law means Parliament does not have to approve each new tariff.

The change is then published in the Canada Gazette.

Is consultation required?

Legally, no. In practice, yes.

The government has reportedly identified potential counter-tariffs on $37 billion in goods that could be imposed quickly and is considering a consultation period of 15 to 30 days.

The government is reportedly also looking at additional retaliatory tariffs on $110 billion in goods.

When the government imposed a 100 per cent surtax on electric and hybrid vehicles from China last year, it was preceded by a month-long consultation in July 2024 on potential responses to unfair Chinese trade practices. It received 232 submissions, including from industry and labour organizations, businesses, provinces, non-governmental organizations and individual Canadians.

U.S. government announces plan to ban Chinese software in connected vehicles

The U.S. Commerce Department proposed prohibiting key Chinese software and hardware in connected vehicles on American roads due to national security concerns. It’s a move that would effectively bar Chinese cars and trucks from the U.S. market and force American and other major automakers in years ahead to remove key Chinese software and hardware from vehicles in the U.S.

Ian Lee, a business professor at Carleton University, says changes to things like taxes and tariffs can have big consequences for Canadian businesses. Lee says that's why it has been standard practice over the years for the Finance Ministry to hold consultations with Canadians and business groups when they are contemplating tax changes.

"That's so that there aren't all kinds of screw ups, and injustices and problems caused that are going to take even more effort to fix or to correct," he said.

How long does it take?

Once the government decides to impose a tariff, it can take effect quite quickly. For example, the federal government adopted an order in council on Sept. 20 to impose the surtax on electric and hybrid vehicles produced in China and scheduled the measure to go into effect Oct. 1. Goods that were already in transit when the measure went into effect were exempted. 

The CBSA has not yet responded to questions on how long it takes the agency to begin imposing tariffs once they are adopted by the government. Companies importing goods also have to make changes to their systems.

How are they enforced?

When goods arrive in Canada, whether by air, truck, boat or train, it is up to the CBSA to calculate how much is due in tariffs.

When there is a change in the tariff rates, the CBSA issues a customs notice to advise importers. 

Importers fill out forms listing the goods they are bringing into Canada, then CBSA officers evaluate the forms and determine how much has to be paid.

What impact would there be on Canadians?

The impact of tariffs could vary widely, depending on the product and the market within Canada.

Lee says some Canadian businesses hit with tariffs on U.S. imports at the border may decide to absorb the cost of those tariffs — at least for a while. Other businesses may decide to pass along the cost of the tariff to buyers and end consumers.

Some may decide to source goods from other countries that aren't subject to a Canadian tariff, he added. 

"There isn't one size fits all," Lee said.

In the end, it is Canadian consumers who risk paying higher prices for imported U.S. goods hit by a Canadian tariff — not Americans, says Lee.

"When all these Canadian are cheering, 'Yeah, let's sock it to the Americans. Well, we're not socking it to the Americans, we're socking it to Canadians."
