For people in charge of recruiting commercial brokers - how do you do it?

I have recently founded my own commercial brokerage. For those of you in charge of recruiting (whether you are the owner or not), how do you approach recruiting? I am especially interested in how you find new agents? Finding existing brokers is easy as they are listed on other brokerages websites, but how should I approach finding new ones? I am in Toronto (Canada) and here you can't buy a list of current real estate school graduates.
