Traffic coming into Toronto is worse - and the DVP is awful going northbound from about 2PM to about 6PM - backing up all the way to Dundas or Queen sometimes, which wasn't normal pre-COVID. The only thing GO doesn't offer is flexibility, especially on the Richmond Hill or Milton lines, where the GO buses aren't as convenient or as fast, especially caught up in that traffic. The new GO bus terminal is nice in many ways, it's more suited to long-distance coaches. I found the old terminal easier to get to and from, especially on a bike.
