Workers rights. I insist that my contracts all say that they are governed by Ontario and Canadian Labour law. I have withdrawn my name from consideration more than once because they insisted on my contract being governed by one state or another's labour laws.
Democracy. The fact that every citizen has the right to vote and equal access to the ballot box in non-gerrymandered electoral districts.
Personal freedom. Canadians have much more personal freedom than Americans. Yes, they have hate speech and guns but we have so much more actual freedom than they do.
Healthcare. You pay WAY more for health insurance in the US and even so they will deny everything and make you fight for it. I have a good friend who quit a job because their insurance company was denying all claims. My sister has osteoarthritis in her spine and needs surgery. Her surgeon is one of the best in the business. Her insurance company overruled her doctor and said that she should take physical therapy...for an irreversible, degenerative bone disease. Physical therapy for six weeks will cause her agony and worsen her condition.
Guns. So many people who shouldn't have guns down there have guns. Gun bravery. Fear. Who needs an AR-15 to do groceries of buy coffee? They're terrified all the time and they're armed. That means they're dangerous.
I could go on...
