Dear Medical Jay,
My experience is as the owner of the clinic. I like the folks who have their own ltd. They seem to know what they are doing and aren't just totally lost when it comes to the tax issues. If you don't want the learning curve, dont go with ltd. You do need to have the book keeping to back it up, and some therapists I've hired are hopeless with that!! I won't try to comment more than that, as british ltd laws are no doubt different from Canada.
