I can't advise about medical care in Ontario but I can you this, that having a coordinated team of doctors is vital for cancer treatment. The institutional setting is the best route for this.
Some here have had their treatment in Canada and I sure that they will respond as soon as they catch up. Brian may have information to help you.

I found a fair amount of information doing a Google search for "cancer centers in Canada". Here is one of them:
