^ Well, it isn't always transit vs auto, it's also transit vs. walking. For example, if you look at the data for
transport mode share for work trips, you will see that Toronto is one of the worst metropolitan areas in Canada in terms of walking mode share, yet the transit mode share is the highest in Canada.
The reason that people in the Toronto CMA use transit so much is because they can't walk anywhere. Outside of downtown, Toronto is not at all walkable, and so people must use transit to get around. It makes more sense to make suburban Toronto walkable to allow suburbanites to walk to their destination instead of wasting money on slow, overcrowded suburban bus routes with 3 minute frequency.
Bus routes with 3 minutes frequency, LRT, subways - these are expensive, and it is the fault of the planners. If planners in the GTA and other Ontario cities weren't so incompetent, the province wouldn't have to subsidize billions of dollars worth of transit to make up for their mistakes. The key is for cities in Ontario to develop in a pedestrian-friendly way, and then drivers wouldn't have that double burden of car/gas costs plus paying extra taxes to fund transit. Win-win for both pedestrians and drivers, rural and urban.
