Check out Corn Hill Nursery on the east coast for a great selection of grapes that grow in Canada. I’m sure there are similar places in central/west. It used to be mostly wine and jam/jelly grapes like Concord you could grow here but now there are more hardy table grape varieties too.
Spinach has been a bit hard to find from non-US. You can start that outdoors now in most places, if you have a cold frame or other protection (or if you live somewhere warm like Victoria or Annapolis Valley). Overall, apparently avocados, garlic, lemons/limes, peppers, eggplant, spinach, and sweet potatoes are the things we are most dependent on imports for. Avocados, lemons/limes and sweet potatoes are a little more difficult to do in Canada but the others are easy to grow here. And I expect that citrus and avocados come from Mexico more than the US. The crops we import the most of from the US are apparently apples, strawberries, avocados, lettuce, cauliflower, broccoli, onions, cabbage, and tomatoes. Other than avocados those are all easily grown in Canada.
Not only that, governments are comprised of people who are paid a fixed salary with no bonuses or incentives and strict conflict of interest rules whose literal only job is to work to make people’s lives collectively better.
