Really? Motorcycles make up 3% of the US road vehicle fleet compared to 2.9% of Canada's road vehicle fleet. Motorcycles despite having a higher fatality rate are still an insignificant source of fatalities as far as the bigger picture goes on either side of the border.
You were talking about Ontario, so don't use Canadian two-wheeled vehicle statistics.
Two-wheelers make up 2.5% of total registered vehicle in Ontario while making up 7.6% of deaths, which is a factor of 3.11. Remember, we don't ride 12 months of the year; jurisdictions where people have longer riding seasons have greater total number of mortality not typically greater ratio. 7.6% of total deaths is not an insignificant number.
