And I'm pointing out that trips within the GTA are not 'commuter routes' on the weekend, they have a major recreational function just like the trip to Niagara Falls. People head to downtown Toronto to see sports games, theatres, go shopping, visit friends, go to the pub, etc.
For clear evidence of how important fares are to intra-GTA ridership, just look at the weekend ridership from the inner 905 to downtown via the subway, compared to GO Transit. Sure, the subway is more frequent, but it's also much slower and less comfortable, so that doesn't explain the entire discrepancy. The remainder of the difference is attributable to the high cost of riding GO Transit, especially when you need to connect to the TTC for your last mile. On those trips, taking the GO train is more than double the cost of taking the subway.
