You didn't mention how old you are. If you're under 30, then you can get a holiday work visa. Allows you to work for short periods of time while you are on holiday. First you will have to do a licence conversion, after that, you can then look for a job. I have a feeling you may have a hard time getting someone to sponsor you to come over to work. For the immigration info try going to Immigration Canada's web site, it may be able to handle the technical type questions.

Unfortuneately most countries make you jump through hoops in order to work there. I had a ton of them to convert my Canadian licence to the Aussie one. I also had to go through the Immigration paperwork, luckily my wife is an Aussie, so that made things easier.
I hope this helps you out mate, eh. (dual citizenship showing through *lol*)
