@Pedram15 you should search and see if there is a local Airbnb Facebook group in Toronto. You will have more chance of finding a co host there I suspect.
My name is Abrar and I am in -experienced co-host but i have experience in handling building management. I am currently working in a building management company. If you are giving me a chance i am very good in communicating and i am willing to meet you at any where in Toronto and we can discuss.
