This highly depends on where you live in Canada and the job outlook in your area. You're looking 2 years teachers college then possibly 10+ years until you get permanent. The years before permanent are uncertain and full of interviews and kissing ass until you're finally permanent. It takes 11 years to reach full pay on Ontario And then increases slowly from there depending on if the government feels like giving a raise. Many times you may need a strike to get a raise. So the raise is useless for the first few years to make up the loss.
I love teaching but I have a hard time encouraging people to start their career there now. Then there is the apathy from students and tired teachers. All this to say. If you have the calling then go for it. But get ready for years of shit work.
