Don't know if you have heard of it, but there is a store that specializes in reptiles/spiders/scorpions/fish in Peterborough, which is a couple hours outside of Toronto, called Animalia. I have bought 2 leos there, the animals are well taken care of, and they have a large variety. They have several different species of monitors, not sure about savannah, but they will also do special orders, so that could be a possibility.
