There are many factors that an insurance company considers when charging you a premium for insurance. You can contact your insurance company to determine if they have used the correct factors for your policy. Perhaps they have not. Insurance premiums are non-negotiable. If all of their information is correct and you are unhappy with the rate you are paying your options include shopping for a new policy.
Insurance rates are filed and set by a government entity. You can request information from the Financial Services Commission of Ontario about the rates that the insured filed and were approved. They should also be able to give you consumer advice about the rate you were quoted and if there are any arguments or laws that you could cite when trying to obtain a lower premium.
Keep in mind that if you have not been insured before that you are going to have higher rates typically then someone that has been insured continuously and has proven themselves to be a good driver and without claims. Since you still have the G1, which is basically a learner's permit, then you have not proven yourself to be a mature driver yet on your own so an insurer is going to be unsure of the risk you will be as a solo driver once you obtain your G2 and then full G license. If you keep progressing through the Ontario graduated licensing system and get a full G license with a clean record your rates should go down.
