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.
