G2 Occasional Driver Insurance

I recently passed my G2 exam and was looking to be added to my families car insurance as an occasional driver. I was added on to 2/3 of the cars in my family (one is my mom's and the other is my sister's who is a newer driver who got her G within the last 3 years). Both vehicles are old (<2010s). I am located in the North York area, am 25+, recently completed a drivers education course (the insurance company did not ask for any proof), completed a university degree and currently am not working as I am currently taking some online courses. I thought that the price would be somewhere in the $100 range as I would only use either vehicle for emergencies or for small errands but was quoted $200. Is this a fair price or should I shop around?
