On September 8, 2026, Canada implemented new retaliatory tariffs against approximately $28 billion in U.S. imports. The move came in response to U.S. tariffs on Canadian goods. Canada is saying it’s a dollar-for-dollar come back.
However, here’s what’s important to your business.
You may still pay the price for these tariffs even if you don’t import directly from the U.S.
The straightforward belief is that tariffs on U.S. products should benefit Canadian businesses. This is just part of the answer. Tariffs are a cost, too.
The duty is typically paid by the Canadian importer when a Canadian business imports a product which is subject to a tariff. That added expense can then “trickle down” the supply chain. Your supplier may increase its prices. You can raise your own, of course. Your customer could end up paying more in the long run.
Such retaliatory tariffs can thus be seen as a tax on Canadian economic activity. They can not only raise production expenses, cut spending, and drive down economic growth, but also boost domestic producers’ expenses.
The reality? A tariff may help one business but hurt another one.
There will not be an equal impact across Canada.
A manufacturer who imports bulk machines would feel it differently than a service business with very little physical utility.
The businesses most vulnerable could be those dependent upon:
Location matters, too.
Modest protection in some provinces and industries may be available from a decline in competition. Others may see higher costs of input without an equivalent benefit.
The big question for a small business owner is not just “What products are tariffed?
It’s the question of “Which of my costs depend on those products?”
This is where the hidden tax becomes a real business problem.
Suppose that your supplier’s costs rise as a result of the new tariffs. They will increase your price. Now you have three options:
None is comfortable.
If you absorb the increase, your margin narrows. Passing it on to the customers will push them back. And if you change your suppliers, you could face quality, availability or transition problems.
That’s why it’s not enough to just consider the revenue. You must be aware of what is going on under it.
If your gross margin has been trending downward, then a tariff-related cost increase might make it more apparent.
Increased costs don’t only affect profit. They have the potential to impact cash flow too.
If you increase your inventory, equipment or material expenses, and customers are still paying on their usual schedule, more cash is bound to get locked up. This can put pressure on sales even if they appear to be healthy.
This is where bookkeeping moves beyond being mere record-keeping.
Your numbers should help you identify:
It may also be necessary to review your projections. These September changes could affect the input costs your original budget was based on and could make them outdated.
Don’t wait for year-end financial statements to find out about the problem. Your monthly numbers can assist you with your response before it’s too late to make a change.
There might be some relief as well.
The federal government has set up a remission mechanism for businesses that are being hard-hit by the new tariffs in some cases.
Not all applications will be eligible.
If your business is impacted in a major way, it is important to know if remission could apply to your situation.
Maintain records of all that you are importing, how the tariffs are impacting your import costs and how that increased cost is impacting your business.
Having good records will help to clarify your situation and can help with any request for relief.
The new retaliatory tariffs in Canada are not just a trade policy. They might be expense, margin, pricing and cash-flow problems for your business.
The worst thing to do would be to believe that the effect stops at the tariff.
It doesn’t.
It can pass down the chain of suppliers, production, pricing, customer demand, and your bottom line.
Those businesses that respond quickly will have more choices.
Review your costs. Revisit your margins. Update your forecasts. And ensure that your books are realistic in showing you what is changing.
You don’t need to figure it all out from a spreadsheet.
