thanks, key quote from the link (for others) "“It is accurate that Canada imposes a tariff of approximately 250% on U.S. exports of certain dairy products into Canada, and even more with Canada’s 25% retaliatory tariffs in place. However, that tariff would only apply if we were able to reach and exceed the quota on U.S. dairy exports agreed to under the U.S.-Mexico-Canada Agreement (USMCA). Frustratingly, the U.S. has never gotten close to exceeding our USMCA quotas because Canada has erected various protectionist measures that fly in the face of their trade obligations made under USMCA."

So I think this supports the point that Canadian politicians are bad for protectionist trade policies, right?
