I was sort of lucky. I come from a family of diplomats, and I have lived around the world, so I didn't really have any trouble in that respect. However, other communities tell me about adaptation issues.
There should be a guide on general qualities, such as punctuality. There should be an explanation of what it means to be a Canadian. The communities know it. They often say that something is very Canadian, that it is very upstanding, and so on. I could write the guide, if you like! The difference is very obvious when we go back home.
