Hi Sarahsativa and welcome! I'm in Haldimand, ON so I'm unsure of who to recommend in the GTA. Sometimes I will check the ratings of dr's on RateMD but it's a gamble. You have to take people's comments with a grain of salt. I do know there are some excellent cardios in Hamilton out of the General Hospital. That is where my Dad had his bypass. They specialize in heart conditions. Also my boss's husband recently had a very rare artery condition (it split in two!) and was treated at the General. The drive isn't bad from your area so it might be worth checking into.
I applaud your being proactive. It's very important when the family history is there and then having lupus as well. All the best :)
