That was my point exactly. Canada and the US share 90%+ of their culture, so it was interesting for two reasons:

1. Why send that kind of a book to a Canadian? 2. It's interesting to read what other cultures might find shocking about US culture.

I'm going to guess that was part of their standard "foreigner moving to the US" package?

One of the parts of that book I remember is that you do not talk to other people while at the urinal.

The only possible explanation I can think of is that such a statement would be targeting the non-Anglo Canadian residents, who may be able to live in relative isolation from what we'd consider mainstream North American culture. Even that explanation seems a bit far-fetched, but perhaps there are semi-detached Asian immigrant or First Nations groups. Interesting anecdote.
