How are you paying $50/year? Bike Share Toronto costs CAD$100/year. If you took advantage of their Presto card discount, that used to be 50% off for the first year of membership, recently reduced to 30% off the first year: https://bikesharetoronto.com/presto/
Bike Share Toronto is heavily subsidized by the city and Ontario, and operates at a loss: https://www.thestar.com/news/city_hall/2019/02/28/bike-share...
