Hi
julie2,
I have relatives living in Ontario. From them I heard that teachers are in a very high demand in Canada.
I have not made any research about it, not I saw actual scientific data. It's what I heard from people living there.

First of all check out the web site of the province where you wish to teach and see what hoops you will have to jump through to be certified. Most provinces will require that you take at least 1 year of teachers training. Note that it is very unlikely once you qualify to get a full time teaching position in the cities. Most teachers start out as substitutes in the various districts. See:
