• No travel to the US
• Absolutely as few American products purchased as possible - to the point of not buying carrots when I can't get local ones
• Closing and deleting my social media accounts and cloud services
• Avoiding American-owned companies whenever possible

In addition, I've been avoiding the worst Canadian companies when possible (specifically, the ones who really don't give a fuck about Canada) - Shopify, Loblaws, and the rest.
