Well you've got the "Big 5"
Jevco/Intact - Any bike besides SuperSport, big $ drop after 1 year with an M1/M2 licence
State Farm - Any bike including SS, but they rate by engine size in CCs. Use G1/G2/G experience (minimum 5 years licensed), not M. BIG drop after age 25.
TD MM - Best if you're a current Post-Secondary student or Alumni, insure all bikes (as I recall) and big drop at 25 and 30.
Primmum - Not familiar with them tbh
Facility (usually Nordic I think) - If you've got nowhere else to turn to, expect one BIG lump sum payment for the year.
There's also Desjardins and a couple other companies that are venturing into Motorcycle Insurance that I don't know anything about.
Without a history of driving and insurance, expect quotes in the neighbourhood of 4000-6000 per year, don't even look at a SuperSport until you're 25. Jevco USED to have a big drop after 1 year of M1/M2 experience but they've been bought out by Intact and things are changing.
