No one has asked me, but I'm going to share anyway. Here are some differences I've noticed between the US and Canada:
In the US:
1. Trident comes in big packages of like 24 sticks
2. You have to wait for your license plates to come by mail
3. When people say "thank you", the accent in the "thank".
4. IHOP, Dennys, etc...
5. Everyone goes to Walmart
6. Enlightened people recycle
7. If you use the left lane, the person behind you has a 25% chance of getting impatient for you to pull over so they can pass
8. On Friday evening, everyone and their uncles are heading into town to party...
9. When you get your hair highlighted at the salon, you get the foil put in, then sit under a hair dryer for 30 min...
10. Baseball, football, basketball...

In Canada:
1. Trident comes in little packages of like, 12 sticks.
2. You get your license plates handed to you when you register your car.
3. When people say "thank you", the accent is on the "you" (and it goes up like a question).
4. No IHOP, Dennys, etc... sniff
5. Everyone goes to Canadian Tire
6. Everyone recycles... even fast food joints have recycling bins along with the trash bins.
7. If you use the left lane, the person behind you has a 75% chance of getting impatient for you to pull over so they can pass
8. On Friday evening, everyone and their uncles are heading to cottage country for the weekend...
9. When you get your hair highlighted at the salon, they don't put you under the hair dryer at all (yaaaayyy)
10. Hockey, hockey, hockey...
