Can anyone recommend a good injector for Botox and filler for nasolabial folds in Toronto?

There are many good physicians in Toronto doing these procedures and you are fortunate in that you also have in Canada Revanesse from Prollenium in Toronto so find a dermatologist who uses this

It is a bit hard to recommend but just make sure to go to a skillful injector with a fellowship or accumulated years of experience with injectables, who is a Board certified dermatologist or plastic surgeon by the Royal College of Physicians and Surgeons of Canada and who would give you a proper assessment. The nasolabial folds are treated by different approaches and not solely by direct injections.

Good luck
