I have worked in Canada quite a few years ago but I have been told that it is basically the same now as it was then.
If you are prepared to fly any type anywhere, including up in the arctic circle, then it is reasonably easy to find employment. If however, you are like me and are basically a fussy bastard, only prepared to fly medium/heavy jet equipment in the warm, you will find employment VERY difficult to find.
Many pilots in Canada will fly their whole careers without ever seeing the inside of a nice shiny jet. Many more will never see anything larger than a King Air / Navajo.
Hope this helps.
