The Future of subway and rapid transit in the GTA

Very odd that there are zero Ontario Line extensions being studied out to 2051???
The diagram looks focused on GO expansion only.

MTO's 2051 plan released a few years ago envisioned the Ontario Line eventually becoming a "loop" line up into York Region. I don't really love that concept, but provincial transit planners are definitely thinking about the next phases of the OL.

except for the 407 crosstown route the rest of routes are all existing conventional railways, no rapid transit extensions. The name of the map suggests these are only some of the assessed rail projects and is only including regional rail lines. I assume the full report would touch on rapid transit extensions like the ontario line though it could also be entirely about regional transit. Hopefully we will find out.
 
After most of those pathetically low numbers that don't come anywhere close to meeting the specified criteria, I suspect these are mostly lines that are no longer in the plan! :)
Immediately, the numbers look pretty off. For the midtown line it looks like the ridership was modled like its a standalone line from yonge to jane which would have a lot less ridership than if they looked at through running onto the milton line or into scarbrorough.

This is (purportedly) from Metrolinx’s 2051 RTP, the next iteration of the 2041 RTP, which followed the Big Move- or, it’s at least from a background study to it. If you look to the 2041 RTP you will see this fits in that format. This is only a fraction of what we will see, though as usual, these plans don’t necessarily materialize into much as-shown.

These were/are items studied in addition to what is already on the table, ie the 2041 RTP +/- what Municipalities (or the Province) has added or removed.

So yes, the full report will show a lot more, some familiar and some new. For example, This RTP will cover the GGH, whereas up till recently Mx only oversaw the GTHA. There are some other scribbles I’ve seen floating around that gives an idea of what we will see in KWC, for instance, if you are curious.

This map also does show other corridors if you know what to look for- this is also my main area of concern. The figure shows 2041 RTP/MTO 2051 corridors in the background (dotted lines) with little to no changes; is that because this is a preliminary study building on the last RTP? Or is it after the fact…? The answer will determine the fate of the OL Loop, although the full RTP will be much more explicit than this.

See the GO 2.0 Expansion thread for my response regarding that, but the Midtown ends up on these docs every time and doesn’t move forward either. Yes, if Mx had integrity with their projections and Corridor ID it would be better, and so on- but the map simply corresponds to where ‘new corridor’ would be needed.

The low projections are essentially for saying “we’re not going to pursue this unless something new enters the picture”- again, as per usual here. The only difference this time is if the Feds are looking, too.
 
Infrastructure Ontario had originally planned the Ontario Line to be a loop where west and east branches meet on a Hwy 407 alignment. I guess we will have to wait to see Metrolinx's full 2051 plan.

It’s a solid map—and reasonably realistic, too. If we added that system, along with extending Line 6 to Seneca Newnham and Line 4 to Keele/Wilson, you could make a strong case that Toronto’s TTC-run higher-order network would be essentially complete.
Thanks. Although there have been comments out there about Ontario Line west someday going to the airport (maybe from politicians? line on MTO map?), Jane LRT was on Transit City for a reason, and I think the N/S connection along the majority of the underground Jane alignment would be more useful than cutting through my old stomping grounds of central etobicoke to run through Renforth.

Only thing I would add is a more ambitious Line 4 western extension to Pearson

I'm not sure every line needs to head to Pearson. We are already talking about Line 3, Line 5, Line 6, and GO UP. If Sheppard was ever to get that far (and I doubt the demand is there, this century at least), it can intersect Line 6 somewhere on Highway 27. It's hard to see much where it can go after Sheppard West without some significant densification somewhere. Maybe Sheppard and Jane with a stop at Keele, to meet the theoretical Jane LRT.
