Turkish Airlines doesn't list a specific physical Toronto office location on their main contact page, focusing on online/phone support (+1-866-829-1086) and their Istanbul HQ, but they operate flights from Toronto Pearson Airport (YYZ) in Terminal 1 for flights to Turkey and beyond. For local support or sales, your best bet is their global contact number, website/app, or potentially an authorized travel agent, as they serve Toronto with flights, not necessarily a large walk-in office.
