Editing Line 3 Scarborough (section)

=== Replacement bus service ===
On April 10, 2019, Ontario premier [[Doug Ford]] announced that Line 3 Scarborough would be replaced by a three-stop extension of Line 2 Bloor–Danforth to be completed by 2030.<ref name="TheStar-2019-04-10"/><ref name="ON-2019-04">{{Cite web|url=https://news.ontario.ca/opo/en/2019/04/premier-ford-unveils-transportation-vision.html|title=Premier Ford Unveils Transportation Vision|website=news.ontario.ca|language=en|access-date=August 9, 2019|archive-date=April 10, 2019|archive-url=https://web.archive.org/web/20190410213847/https://news.ontario.ca/opo/en/2019/04/premier-ford-unveils-transportation-vision.html|url-status=live}}</ref> However, on December 10, 2020, Toronto mayor [[John Tory]] stated that Line 3 was likely to fail and be taken out of service before the Scarborough Subway Extension was completed, with the failure possibly happening several years before completion.<ref name="RTfail">{{cite news|last1=Pagliaro|first1=Jennifer|date=December 10, 2020|title=Scarborough RT will shut down before subway is finished, mayor says|newspaper=Toronto Star|url=https://www.thestar.com/news/city_hall/2020/12/10/scarborough-rt-will-shut-down-before-subway-is-finished-mayor-says.html|access-date=December 10, 2020|archive-date=December 10, 2020|archive-url=https://web.archive.org/web/20201210155912/https://www.thestar.com/news/city_hall/2020/12/10/scarborough-rt-will-shut-down-before-subway-is-finished-mayor-says.html|url-status=live}}</ref> At that point, the Line 3 vehicles were 35 years old, a decade past their 25-year life expectancy, and had become unreliable and difficult to maintain, leading to reduced service and frequent service interruptions. The TTC was looking into an alternative solution of replacing Line 3 with bus service.<ref name="TTC-2020-10-22">{{cite web|date=October 22, 2020|title=Chief Executive Officer's Report – October 2020 Update|url=http://ttc.ca/About_the_TTC/Commission_reports_and_information/Commission_meetings/2020/October_22/Reports/1_Chief_Executive_Officer_Report_October_2020_Update.pdf|archive-url=https://web.archive.org/web/20201018020617/http://ttc.ca/About_the_TTC/Commission_reports_and_information/Commission_meetings/2020/October_22/Reports/1_Chief_Executive_Officer_Report_October_2020_Update.pdf|archive-date=October 18, 2020|access-date=October 17, 2020|publisher=[[Toronto Transit Commission]]|pages=10–11}}</ref>

In February 2021, the TTC recommended shutting down Line 3 permanently in 2023 and replacing it with bus service. The TTC rejected doing a third overhaul of the line because it would cost $522.4{{Nbsp}}million and might not improve its reliability. The TTC offered two bus replacement options: purchase 60 hybrid buses by 2023 for $374.8{{Nbsp}}million or reduce the number of spares for maintenance, deferring the purchase of new buses until 2027 to 2030, at a cost of $357.4{{Nbsp}}million.<ref name="TheStar-2021-02-04" />

In April 2022, the TTC recommended that the Line 3 right-of-way between Kennedy and Ellesmere stations be converted into a {{convert|4|km|adj=on}} dedicated busway after the Line 3 closure. There would be stops along the right-of-way at Mooregate Avenue / Tara Avenue (approximately halfway between Eglinton Avenue and Lawrence Avenue), Lawrence Avenue East and Ellesmere Road. Between the proposed Ellesmere stop and Scarborough Centre station, buses would operate along Ellesmere Road and Brimley Road. Midland and McCowan stations, along with the connecting guideway, would be permanently shut down as they were deemed not usable for a busway. The busway would operate until the opening of the Line 2 Scarborough subway extension, after which its disposition was not known.<ref name="TTC-SRT-Future" />

By August 2023, newly elected mayor [[Olivia Chow]] had promised to build the busway, which was estimated to cost $55{{Nbsp}}million. The project is estimated to take two years to complete.<ref name="TheStar-2023-08-28">{{cite news |url=https://www.thestar.com/news/gta/ttc-ends-scarborough-rt-service-permanently/article_1a402fc5-26b7-56d5-b564-128240e747c0.html |title=Shuttering of Scarborough RT means the end of a transit system that changed the city |newspaper=[[Toronto Star]] |date=August 28, 2023}}</ref>

By the fourth quarter of 2023, the TTC planned to set up dedicated bus lanes via Kennedy Road (northbound) and Midland Avenue (southbound) to run buses express between Kennedy and Scarborough Centre stations. Bus lanes would be painted red and transit signal priority would be implemented.<ref name="TTC-SRT-Future" /> An additional $60{{Nbsp}}million would be required to modify the bus platforms at Kennedy and Scarborough Centre stations.<ref name="TheStar-2022/04/07">{{cite news |last=Spurr |first=Ben |date=April 7, 2022 |title=Scarborough RT may find new life as a multimillion-dollar dedicated bus lane |newspaper=[[Toronto Star]] |url=https://www.thestar.com/news/gta/2022/04/07/scarborough-rt-may-find-new-life-as-a-multimillion-dollar-dedicated-bus-lane.html |access-date=April 8, 2022 |archive-date=April 8, 2022 |archive-url=https://web.archive.org/web/20220408011611/https://www.thestar.com/news/gta/2022/04/07/scarborough-rt-may-find-new-life-as-a-multimillion-dollar-dedicated-bus-lane.html |url-status=live}}</ref> With the dedicated lanes, a trip between Kennedy and Scarborough Centre stations would take 17 to 22 minutes versus 15 minutes using the future busway. The duration of the same trip on Line 3 was 10 minutes.<ref name="TTC-bus-replacement" />

Work on the dedicated bus lanes was expected to be completed by November 19, 2023, when Line 3 had been scheduled to shut down. However, due to the derailment of a Line 3 train on July 24, 2023, the TTC decided to end Line 3 service three months earlier. The dedicated bus lanes began service on August 26, 2023, without the bus lane work having been fully completed. Up to 70 buses per hour will use the dedicated lanes.<ref name="TTC-SRT-Future" />

By January 2024, the estimated cost of converting the Line 3 right-of-way into a bus roadway had increased by $12{{Nbsp}}million to $67.9{{Nbsp}}million. Planning was 60 percent complete. If approved by city council, work would start in 2025 for completion in 2027.<ref name="TheStar-2024-01-22">{{cite news |url=https://www.thestar.com/news/gta/scarborough-busway-may-not-be-completed-until-at-least-2027/article_835f81dc-b947-11ee-b73c-cb1259add6af.html |title=Scarborough busway may not be completed until at least 2027 |newspaper=[[Toronto Star]] |date=January 22, 2024}}</ref>
