Hi Alfie,
Toronto is a good place to look for a job in the IT industry. I don't think you will be paid less because you are a recent immigrant. The lack of "Canadian experience" may be a reason for some recruiters to try to lowball you, so be aware of it. Try to contact recruiting agencies - most of the IT jobs go through them. because you are coming from England I have to warn you not to expect many, if any returned calls and emails. For some reason here recruiters think that a common courtesy of returning phone call is not necessary unless they can profit from you.
Good luck!
