Someone else shared this article [1] and I was reading a quote I thought was interesting:

  “[Canada] has a large dairy producing constituency that it wants to protect, so they put a cap on imports that can be accessed at a competitive rate. That's what we call a ‘TRQ’ (tariff rate quota),” says Becky Rasdall Vargas, senior vice president of trade and workforce policy at the International Dairy Foods Association. Under the TRQ, Canada accepts a certain amount of dairy products duty-free, without tariffs.

  "Rather, Rasdall Vargas blames the dispute on “a systemic set of failures” by Canadian administrators that intentionally prevent American dairy exports from reaching the import cap. These protectionist measures are intended to support Canadian dairy farmers. One rule, for example, requires that Canadian dairy processors be the primary recipients of American dairy products.

  “If you’re a U.S. exporter, you're going to want to sell to your customers, not to a competitor,” she says. “Another one is that retailers aren't eligible to obtain an import license quota in Canada. There are layers upon layers of rules that ultimately prevent U.S. exporters from being able to fill those quotas.”

So I'm not sure the quota is as straightforward as many folks are making it out to be and there's more nuance there. This, assuming it is accurate, is really interesting and helps explain why US producers don't even meet the quota that was set.
