Holy crap, they absolutely gutted the Stouffville and Barrie weekend timetables, leaving gaping holes not filled by any replacement bus. For example, they cancelled the 19:13 and 20:13 trains, leaving you no way to get to the 20:12 and 21:12 route 70 buses.

The Barrie line was similarly gutted, yet bizarrely there are still those awkward trains heading to Barrie, which require tons of deadhead movements. Personally I would have kept the regular hourly service to Aurora and sacrificed the midday trips to Barrie, since at least there is a bus alternative. Even if there were a bus replacement, getting a bus into Union station is a nightmare nowadays, so that would be a terrible option.

As previously noted, the Niagara weekend train service has now been cut in half, operating with a single trainset rather than two. The morning departure from Toronto (10:07) seems a tad late, not arriving in Niagara until past noon. Hopefully when tourist season comes back around they will add an additional departure at 09:07.
Due to the temporary closure of St Catharines station, weekend GO trains now travel 77 km non-stop from Aldershot to Niagara Falls in 75 minutes, which is by far the longest station-to-station distance and time in the network.
