Plans for the Scarborough Subway extension and Scarborough Busway keep changing. I'm finding it hard to keep up! There is not much activity happening on the subway extension and busway threads, so I'll ask some questions here, because they affect OL too.

First question: "Wither Line 3?"
Originally, the Line 3 designation was to be retired. Then it was reassigned to the Ontario Line, and Wikipedia still says OL will be Line 3. (And so does the title of this UT thread!)
Then the TTC decided to call the busway Line 3 as well, since it was only supposed to be used until 2030, the original opening target date for the Scarborough Subway extension to Bloor / Danforth, and also for OL.
As I understand it, the target date of 2030 for the subway extension has been rescinded, and currently there is no target date for it.
Now it has been announced the busway will be permenant as a local route to run alongside Scarborough Subway after the latter opens.
Currently, the TTC's page for the busway still calls it line 3, and as far as I can tell, they do not have a page about OL.
Metrolinx does have a page for OL, but they do not mention a line number.
So... there there is no longer a plan to call OL Line 3, and no new number has been assigned?
Have I got anything wrong here?

Second question: "Wither Lawrence East Station?"
The original plan was to reuse the Lawrence East Station name as a new station on the Scarborough Subway extension. But now they are reopening the old station under its old name, according to TTC's website. I doubt both stations will have the same name, but since the TTC's site shows the old name on the busway map, to open in September, it suggests that name has been firmly decided, so the subway extension station will need to be assigned a new name. But nobody's saying anything about that. Any ideas?
I looked at the site that I think you are referring to.

"Scarborough Busway (Line 3 Bus Replacement)" is what they are calling the new BRT right-of-way. Note, it is not a single line. It will be multiple bus lines that will use the busway to speed up service.

Okay, so "Line 3 Bus Replacement" means a busway replacing Line 3, not a busway as replacement that is going to be called Line 3. That's probably the explanation, but it sure is ambiguous! In Wikipedia's article for line 3, the final paragraph calls it the Line 3 Busway, and perhaps the writer had the same misunderstanding that I did. Despite all that, I don't see any official references to OL as line 3, and I still wonder if a change in plan is in the works.

It was official as of 2021, but not sure if thats still the official plan. this is all we have to go on.
 
Updates from today.

Province Breaks Ground on Ontario Line Elevated Guideway and Four New Stations


Project supporting 4,700 jobs annually during construction and bringing nearly 230,000 more people within walking distance of transit


February 18, 2026
Premier's Office


TORONTO — The Ontario government has officially broken ground on the elevated guideway and four new stations for the Ontario Line subway, marking a major milestone in the province’s plan to protect Ontario by creating jobs, cutting commute times across the Greater Toronto Area and bringing nearly 230,000 more people within walking distance of public transit.


“Our government’s historic $70 billion investment in public transit across the province is helping protect workers in the face of tariffs and economic uncertainty and fight gridlock by getting transit users where they need to go faster,” said Premier Doug Ford. “The Ontario Line will be a game-changer for GTA residents, cutting travel times across Toronto and offering more than 40 convenient connections to other transit services across the region.”


Crews have begun work along the three-kilometre elevated guideway, a raised stretch of track that will connect Don Valley, Flemingdon Park and Thorncliffe Park stations, where ground has also now been broken. This section will bring 30,500 people within walking distance of a subway stop and improve access to 14,800 jobs in the area.


“Under the leadership of Premier Ford, our government is making historic investments in transit, including the largest subway expansion in Canadian history,” said Prabmeet Sarkaria, Minister of Transportation. “The Ontario Line is at the centre of our government’s $70 billion plan to build and upgrade transit, helping to fight gridlock and keeping thousands of workers on the job in the face of tariffs and economic uncertainty.”


The province is also breaking ground at Cosburn Station, which will connect riders across the city to Toronto’s Pape Village neighbourhood for the first time and cut commute times for more than 10,000 people. Once complete, the 15.6-kilometre Ontario Line will have 15 stations, running from Exhibition Place through the downtown core and connecting to Line 5 Eglinton at Don Mills Road.


“The Ontario Line will connect people and communities across our city, helping hundreds of thousands of Torontonians get where they need to go faster and more reliably,” said Olivia Chow, Mayor of Toronto. “This new line will bring more people within walking distance of transit, reduce congestion on our roads, and make daily commutes shorter for families and workers. As Mayor, I am committed to keeping the TTC affordable by freezing fares for three years while increasing service and improving reliability. We are also introducing fare capping this year so Torontonians can ride more and pay less. The City and Province will continue working together to deliver affordable and convenient transit that keeps Toronto moving.”


As part of the government’s plan to protect Ontario, the province is investing $70 billion in the largest expansion of public transit in North America to shorten travel times, reduce gridlock and drive economic growth across the region. This includes covering over 80 per cent of capital construction costs on Ontario Line.


“The Government of Canada is proud to partner with the Government of Ontario to build projects that will deliver efficient, sustainable and affordable public transit in Toronto,” said Julie Dabrusin, Minister of the Environment, Climate Change and Nature and Member of Parliament for Toronto—Danforth, on behalf of the Honourable Gregor Robertson, Minister of Housing and Infrastructure. “Advancing construction of the Ontario Line’s elevated guideway and four new stations means we are another step closer to enhancing connection and productivity in our nation’s largest city. Together, we will build a stronger and more resilient Canadian economy for everyone.”



Quick Facts


• The elevated guideway will carry Ontario Line trains up to 14 metres above street level, starting at the west end of Overlea Boulevard in Thorncliffe Park and running north to Don Valley Station at Don Mills Road and Eglinton Avenue East.


• In October 2024, the province broke ground on two new bridges over the Don Valley, laying the foundation for faster transit and cutting travel times by more than half for families and workers along the route.


• In July 2024, the province broke ground on the Ontario Line’s Pape Station. To date, crews have excavated 20 per cent of the site, roughly 24,000 cubic metres of soil.


• Pape Station will serve tens of thousands of commuters every day. The Ontario Line is expected to reduce rush hour crowding at the TTC’s Bloor-Yonge Station by up to 22 per cent, about 14,000 fewer people.


• The Ontario Line will support 4,700 good-paying jobs annually during construction, protecting Ontario’s workers amid economic uncertainty.


• The Ontario Line will offer more than 40 connections to other transit services, reducing daily car trips by at least 28,000 and cutting greenhouse gas emissions by 14,000 tonnes annually.


• The Ontario Line will support almost 390,000 daily boardings and reduce travel times from Thorncliffe Park to downtown Toronto from 40 minutes today to 25 minutes.


• Once complete, the Ontario Line will make it faster and easier to travel across the city. A trip from Pape and Danforth to Queen and University will take less than half the time, going from 25 minutes today to 12 minutes.


• During peak periods like the morning rush hour, the Ontario Line will reduce crowding by up to 15 per cent on the busiest stretch of TTC’s Line 1 between Bloor-Yonge and Wellesley.


• As part of the Transportation Plan for the Greater Golden Horseshoe, the province is delivering the largest subway expansion in Canadian history with the Ontario Line, the Scarborough Subway Extension, the Eglinton Crosstown West Extension and the Yonge North Subway Extension.


• The Government of Canada is contributing over $4 billion toward the construction of the Ontario Line.
