Canadian Snowbird Association warns travellers to leave Canadian beer, wine and spirits at home — and you better check your protein powder, too

In economic terms, the move is modest. The ban covers roughly US$967 million in Canadian imports, with alcohol making up 87% of that, according to analysis by the American Action Forum, a centre-right U.S. think tank. For individual travellers, though, the impact is personal.

Here’s what to know before crossing the border.

What’s banned — and why now?

The ban stems from a Sept. 8 proclamation signed by U.S. President Donald Trump that excludes certain Canadian alcoholic beverages from entering the country. The White House says it escalated from tariffs to a ban for two reasons. Canadian provinces kept American alcohol off government store shelves, and Saskatchewan announced a new 50% levy on U.S. alcohol.

According to the CSA, the current banned list of adult beverages includes all Canadian-origin:

• Packaged beer
• Sparkling wine
• Many table wines
• Cider
• Sake
• Rum
• Vodka
• Gin
• Certain whiskies and other spirits

But there are additional bans that cover items travellers may not expect, including:

• Whey protein products
• Molasses
• Non-alcoholic beer
• Motorcycles
• Fishing rods

Protein-maxxers: Beware of your whey powder origins

The ban on Canada’s dairy products was in retaliation for Canada’s 50% tariffs on U.S.-produced dairy products. That ban extends to 52 dairy products, including liquid, powdered and most other forms of whey, the liquid component of milk that provides about 20% of its protein.

For Canadian travellers accustomed to taking their routine health supplements, these latest trade-war restrictions means reading labels before setting off for down south. It could also mean paying a little more for similar products south of the border.

Does the ban apply to items for personal use?

Can you get stopped at the border for bringing in Canadian-origin items? This is a grey area. Trump’s proclamation doesn’t carve out an exception for small, personal quantities. Instead, it authorizes U.S. Customs and Border Protection (CBP), the agency that polices U.S. ports of entry, to issue rules and guidance to administer the ban.

Under standard rules, the CBP lets Canadians aged 21 and older to bring in 1 litre of alcohol duty-free for personal use. Keep in mind, these are CBP rules, as there’s no federal cap on larger personal amounts; however, big quantities can be flagged as commercial.

But those are the standard rules — rules written for goods allowed in, not for goods that are banned. It doesn’t mean that personal consumption quantities could raise flags — and prevent crossings.
