It is my understanding that you have to have auto insurance with State Farm for them to write a motorcycle policy. There is no info on their web site.
TD Canada Trust
TD Canada Trust have a handy online quote form. In a few minutes you can have a quote and try out different collision and comprehensive options. TD insurance is provided by Primmum. I don't know if the rates are the same but I suspect that they are.
CAA offer motorcycle insurance with discounts for CAA members and multiple bikes.
