Polite Canadian jokes

Perhaps to take my mind off our very impolite world infamous mayor, I thought of a new polite Canadian joke on my dog walk.   But first, my two favourite (the second updated for a holiday theme). 

1. Why did the Canadian cross the road ?   To get to the middle.   

2. How does a Canadian get 200 crazy guests to leave their house Christmas party ?   They say "excuse me, would you mind going home now please ?"

3.   What does a Canadian say when he sees a really suspicious looking dude in their neighbourhood ? "Can I help you ?"
