First of all, you need a market as a salesperson. Toronto's market is bigger than Ottawa, right? you know, the number of Chinese persons in Toronto is bigger (>>>) than Ottawa. I guess you must develop your clients in Chinese group at the beginning time. Secondly, it's more convenient and economic to get all certificates to meet qualifications of a Real Estate Broker/salesman because most of related administation organizations are located in Toronto. By the way, have you noticed that most of signs of selling house are posted by none-Chinese? I mean, you will find a lot of difficulties to foundation your base here.
Just my comments. Up to you.
