U.S. President Donald Trump has escalated his trade war with Canada, announcing 50 per cent tariffs on a range of Canadian goods, from wine and hockey sticks to cement and dairy products. The new rates will take effect in 30 days.The White House claims the increase, imposed under a rarely used provision of the Tariff Act, is in retaliation for Canada’s “discrimination against and unreasonable and unequal treatment of U.S. commerce.” It points specifically to Ontario and Québec restrictions on American alcohol sales.Those provincial restrictions are part of a massive boycott of alcoholic beverages. Eleven provinces and territories have avoided importing U.S. alcohol for the past 16 months. Most cleared out their existing stock last year, though Ontario and Québec still hold about $96 million worth.Trump’s tariff announcement makes this an opportune time for those two provinces to put their existing inventories back on the shelves while maintaining their import bans. That would offer a diplomatic gesture to U.S. officials while saving provincial taxpayers millions of dollars.Canada’s premiers are meeting this week in Prince Edward Island to discuss the country’s biggest challenges. Their discussions will likely include the alcohol standoff.United in theory, divided in practiceThe booze ban began in February 2025 in response to Trump’s initial tariffs on Canadian goods. All 13 provincial and territorial governments ordered their liquor agencies to stop selling U.S. alcohol and to stop ordering more.The boycott was short-lived in Alberta and Saskatchewan. They both resumed buying and selling American booze in June 2025.The other 11 governments remain united in banning alcohol imports. But they’ve differed in how they’ve handled their existing stock.British Columbia, New Brunswick and Yukon stopped selling U.S. alcohol in government liquor stores but cleared out their stocks via wholesale sales to restaurants and bars.Manitoba, Nunavut and the Atlantic provinces began selling off their inventories last year. Some discounted the prices and donated part of the proceeds to charity.Québec resumed sales in February, but only for products with short shelf lives. As of March, it still held U.S. alcohol worth $17 million.Ontario, by contrast, hasn’t sold any of the $79 million worth of U.S. inventory it pulled off shelves. As a result, it had to write off $2.6 million in expired product and spend $8 million to store the remainder. It has also forgone millions of dollars in interest from having that money unproductively tied up.Not surprisingly, these provincial actions have drawn U.S. attention.Washington feels the pinchBecause of the bans, U.S. alcohol producers’ exports to Canada plunged 76 per cent for wines and 46 per cent for spirits in 2025, representing a loss of about $725 million in sales. That equates to about $62 million for every month the dispute continues, or about $1.2 billion so far. Imports by Canada from the U.S. of alcoholic beverages, in millions of Canadian dollars per year. (Statistics Canada), CC BY U.S. producers worry about losing market share over the longer term. Canadians are getting accustomed to sipping local wines and spirits instead of American ones. Some may never switch back.Those industry pains have prompted U.S. politicians to complain. This month, for instance, a Republican congresswoman proposed legislation to punish the boycotting provinces, while a Democratic senator pleaded for provinces to resume selling California wines. Now Trump has followed through with tariffs of his own on top of an earlier threat to hit Canada with levies over cross-border wildfire smoke.Of course, getting U.S. attention was a key goal of the provincial boycotts in the first place. Having achieved that, Ontario and Québec now have an opportunity to diplomatically deploy their American alcohol stockpiles.Sell the stock, keep the banSo far, neither Ontario nor Québec is backing down from their bans.But they could instead seize the moment to resume business-as-usual retailing of their existing U.S. inventories, while continuing to ban imports. Resuming sales makes economic sense. That liquor has already been paid for. Storing it any longer has no financial impact on U.S. producers, but it costs provincial taxpayers nearly $1 million a month.Selling it off instead at regular prices — roughly double the wholesale cost, in line with typical liquor-board markups — would yield about $163 million for Ontario and $33 million for Québec.Diplomatically, resuming retail sales of existing inventory would offer a goodwill gesture to U.S. trade negotiators while the continued import ban would keep the pressure on.This approach would also set a symbolic timer on Canada-U.S. trade talks, with existing provincial alcohol inventories draining away like sand in an hourglass as American producers watch.And it would remind Americans that Canadian politicians do not hate the U.S. alcohol industry. They just want Trump to honour the trade deal he signed with Canada in 2020, which he once called “the largest, most significant, modern, and balanced trade agreement in history.”What comes nextTrump’s new 50 per cent tariffs, if they actually happen, will cause financial stress for many Canadian firms. But as with his previous rounds of tariffs, this new batch will mostly be paid for by U.S. consumers through higher prices, further fuelling U.S. inflation. They will also likely face legal challenges in U.S. courts.It’s always difficult to predict Trump’s next moves. He repeatedly changes his mind and constantly “bullshits.” Are his latest tariffs truly a response to Canada’s trade practices, or does he just want to divert U.S. voter attention from the mounting casualties and costs of his failing war with Iran?It looks unlikely that cross-border trade will get back to pre-Trump normal anytime soon. But if it somehow does, that will be something for Canadian and U.S. consumers to drink to.Michael J.
