I went with Dalton Timmis and the quote to cover two motorcycles was reasonable (slightly more than I had been paying for one). However, once the coverage process was rolling, I had to get safety certification for both bikes - this cost $100.00 each... that adds a lot to the annual bite (only for the first year, but still...).
Check what extras are required before committing.
Insurance for Toronto will be pretty high $$$. The rules are stacked against riders in Ontario to start with, and TO gets the highest rates in province.
