Again, the affordability argument is a straw man in the context of the $10 weekend passes, because those passes do little to nothing to address affordability for most potential GO Transit trips.
A 260 km round trip to Niagara Falls on a $10 pass works out to $0.04/km. Meanwhile a 34 km round trip from Downsview Park works out to $0.29/km.
Or relative to the normal ticket price, a round trip from Downsview Park gets a 3% discount, while a trip to Niagara Falls gets a 72% discount.
Why is it that we are arbitrarily dumping money into getting high-occupancy vehicles off the QEW to Niagara, when for the same money we could divert far more single-occupancy vehicles elsewhere? Surely you'd get far more vehicles off the road by providing a (for example) 40% discount for all trips.
Claiming that the $10 round trip to Niagara is a worthwhile investment in transit affordability can only make sense if you assume that there is an unlimited amount of funding available for GO Transit's operations, which is not the case. There is a finite budget, and funds which are bankrolling day trips to Niagara are funds which are not providing discounts on trips within the GTA, or between other nearby cities. Those are also funds which are not being used to run additional service - something which is also known to attract people out of cars.
And besides, the baseline on GO is not $40 round trip, the baseline is
$25 round trip including a WEGO day pass, which is what most passengers were paying prior to the $10 pass. A price of $12.25 each way already undercut all of the competing services and was already attracting very solid ridership on weekends.
Here are the cheapest round trip tickets I could find for next Saturday, on competing services:
Flixbus: $43

Megabus: $50

VIA Rail: $54

Rider Express: $60

To reiterate: my point is not that these are reasonable prices, the point is that the marginal number of riders attracted by reducing the GO round trip from $25 to $10 is definitely fewer than the number of riders which would be attracted by the spending the same amount of money on discounts elsewhere.
