Teaching English in ontario as a teacher with 25+ years of experience.

Hey everyone. i wanted to ask about the procedure to apply for teaching jobs in canada (ontario, british columbia, alberta,..). I asked google and i wasnt pretty much convinced because it said i have to apply to WES (?), then land in canada and then search for jobs at schools. i have 28 years of experience in teaching English in a public school in Dubai. and I'm Moroccan. This is urgent please
