Unfortunately there's no easy answer. It's typically quite difficult to find a job in Canada from outside of Canada. Also, if a Canadian employer wants to hire a foreign worker, they usually have to prove that they couldn't find a Canadian to hire for the job. This takes a lot of paperwork and time. For this reason some/many Canadian employers aren't very interested in hiring foreign workers.
To start, try searching for jobs on Canadian job sites such as monster.ca.
Good luck!
