Questions About Ontario Auto Insurance

I've been browsing websites for a used car lately to tide me over for a while. I also took a look at auto insurance, since Ontario premiums are notoriously high. I'm worried the insurance will cost more than the car...

I just checked my premium on TD's website and wanted to ask fellow car owners: is the default quote from the insurance company for full coverage? If I remove the optional items on the second page, would that give me the standard third-party liability coverage? After all, there's a difference of over a hundred dollars a month. #TorontoCarBuying
