What happened
The US-Canada trade war escalated on Tuesday as a US ban on nearly $1B of Canadian alcohol, dairy and motorcycles took effect, on top of Canada's tariffs on about $20B of US goods. Alcohol makes up 87% of the banned goods; the rest is dairy such as whey, and motorcycles with engines above 800cc. A trade lawyer says many of these goods already faced a 50% tariff that acted as a de facto ban. Canada's own tariffs of 15% to 50%, worth about $20 billion, took effect September 8.
Why it matters
The US-Canada trade war is now moving from higher taxes on imports to outright bans, so some products cannot cross the border at any price. The 50% tariffs cover only about 5% of Canada's goods exports to the US, and the Canadian dollar has barely reacted. The ban still hurts specific businesses, such as BRP, which builds the Can-Am Spyder and Canyon three-wheelers in Quebec, though BRP calls the impact limited.
