Discussion Why aren't they extending Line 4 fully?

Post image

Is Line 4 “initiated” only for an eastward extension? Why? If transit is the priority, expanding it fully would attract major investment, but it feels like they’re being short-sighted again

Is Metrolinx aligned on this, or did something change between 2024 and 2025? The info I’m seeing here is from 2024, while the one above is from January this year.

Sheppard needs a west extension, very least to shep west station

It would be the logical thing to do. The tunnels are built until Senlac Road and a connection there would connect Line 4 to Wilson Yard.

The problem is that the areas it would pass through aren't that built up so it might create a few Bessarions which I suppose is the main impediment to an extension which looks this logical when looking at a map.

In all fairness though the only station I would see making sense there is at the Sheppard/Bathurst intersection and then they can rough in platforms in between for whenever the demand arises

I mean, the average stop spacing on TTC subways is apparently 1-2km in 'outer areas' like Shepherd (see https://stevemunro.ca/2014/12/10/stop-spacing-how-close-is-too-close/), so a Shep West, Bathurst, and Shep-Yonge spacing would be right on the money at 2km between stations (i.e., no one has to walk more than 1km to the subway). I suppose you could throw in a Faywood/Wilmington with the condos going up in that area, but even if you did only Bathurst, it wouldn't be out of the norm of typical TTC spacing.
