Not in Toronto, but Mississauga - we’ve used VS LLP as they came highly recommended from some locals. They did our first Canadian tax return and seemed to all go well. They’ve also given us loads of information (they don’t charge for meetings at all) which has been super helpful.

Havent linked their website as it as it seems to be down just now - I promise they are in business as I just met with them a couple of days ago. You’ll get their number if you google them.
