If you were going to take that tariff money to build up a local tomato industry it might make sense, Canada already has a growing hot house industry. But don’t kid yourself, tariffs cost the consumer and for low margin highly seasonal and subject to going bad goods like produce is about the worst case scenario.
If you want people to buy stuff from you Americans then just try to stop pushing forward American imperialism down into everyone's throats. This isn't just about money, it is about my country's sovereignty.
We get to get taxed on the other side by paying more for Canadian goods.
