While Toronto's big transit dreams are understandably tied to the Downtown Relief Line (or whatever you want to call it these days), it's worth bearing in mind that the city's congestion issues extend across the GTA and beyond. That's why keeping tabs on Metrolinx's plans for widespread expansion of the GO Transit network over the next decade is worth keeping tabs on.

There are as many as 50 new GO Stations being considered for the network during this span, a number of which will increase access to commuter rail from downtown Toronto (and thereby help to mitigate congestion at Union Station). You can check out the long list of stations at this page, which includes some of the proposed SmartTrack route.

A decade is, by all realistic standards, too short a period to roll out such an extensive expansion, but the scale of thinking going on here is at least encouraging. Beefing up GO Transit in Toronto has long been a missed opportunity for a better integrated transit system in the city, even before SmartTrack was on the table.
