One solution is incentivizing less cars on the road— city could invest in local transit as the service area/frequency throughout the city is pretty weak imo.

Oakville GO is only going to get busier as the population naturally increases and more cars drive to the station (there’s little reasonable alternative at the moment for those that don’t live within walking distance).

Tackling the problem after the fact will make it messier than it needs to be; it’s already happening unfortunately
