So I've been planning a Working Holiday to Canada for a few months. A few things puzzle me.

I am from Australia and my girlfriend came from Canada to Australia just recently with only $2,000. The thing that puzzles me is that one of the requirements is that you have sufficient amount of money to come to Canada and have evidence of additional funds to leave Canada.

Do they check this on arrival or is this protocol? For those who have done working holidays to Canada, what have they checked at the Port of Entry?
