It might be difficult to notice sometimes, like watching a (giant) pot of water slowly come to boil, but Toronto is building new rapid transit. By 2025 (all being well) the Spadina line extension to York Region (which we recently got a peek at), the Eglinton-Crosstown and Finch West LRTs, and Scarborough subway will more than likely be complete. As a result, the TTC's longstanding system map will require a major overhaul.

The map above (full size here,) uploaded to Wikipedia by user Craftwerker late last month, shows the full extent of those changes.

In total, the city is due to add nine new subway and 40 light rail stops over the next 10 years. That is, of course, assuming there isn't a flip-flop on any of its existing commitments and the ongoing and upcoming construction projects wrap up roughly on time (2025, instead of 2023, allows for an overrun of several years on Finch West and in Scarborough.)

It's also possible other lines could be added to this map before 2025 (we live in hope, right?) The East Bayfront LRT that would run from Union Station to Parliament St. via Queens Quay has been kicked around for years. An environmental analysis was completed in 2010, but so far the funding for the project, which has an option to be extended into the revitalized Port Lands, hasn't been forthcoming.

One thing's for certain: there won't be a downtown relief line on the map for a while.
