Editing Line 4 Sheppard (section)

==Future expansion==
Several informal proposals have been made to extend the line in both directions. The original proposal for the Sheppard line was for a major subway line running from [[Sheppard West station]] on the University portion of Line 1 to [[Scarborough Centre station]] on [[Line 3 Scarborough]]. Instead, funding was only approved for a truncated line with the possibility of several phased expansions. 

In the mid-2000s, under the [[Transit City]] plan, a [[Sheppard East LRT]] was proposed instead of an eastern subway extension. Despite various approvals, the construction of the line did not proceed as the construction of the [[Line 6 Finch West|Finch West LRT]] was deemed a priority.<ref name=":0" /> 

In 2019, the provincial government under Premier [[Doug Ford]] announced it supported an eastern extension of the line as a longer-term project.<ref name="CBC-2019-04-04">{{cite news |date=April 10, 2019 |title=What you need to know about Doug Ford's contentious plan for transit in the GTA |work=CBC News |publisher=Canadian Broadcasting Corporation |url=https://www.cbc.ca/news/canada/toronto/doug-ford-toronto-transit-plan-1.5091916 |url-status=live |access-date=December 21, 2019 |archive-url=https://web.archive.org/web/20191231172534/https://www.cbc.ca/news/canada/toronto/doug-ford-toronto-transit-plan-1.5091916 |archive-date=December 31, 2019 |quote=The province says it "remains committed" to extending the Sheppard subway line from its current terminus at Don Mills station to McCowan station, where it would meet the Scarborough subway extension.

On March 20, 2024, City of Toronto staff presented a report to city council on corridor evaluation results for the prioritization of planned higher-order transit projects, which yielded the following results for a subway extension: eastward from [[Don Mills station]] to McCowan Road (interchange with the [[Scarborough Subway Extension|Scarborough subway extension]] of Line 2) and westward from [[Sheppard–Yonge station]] to [[Sheppard West station]] (second lowest priority).<ref>{{Cite web |title=Agenda Item History |url=https://secure.toronto.ca/council/agenda-item.do?item=2024.EX12.5 |access-date=2024-12-11 |website=toronto.ca |language=en}}</ref>

===Eastward extension===
The TTC considered the eastward extension of the Sheppard line to Scarborough Centre station as one of its top priorities for rapid-transit expansion, which would have expanded [[rapid transit]] in [[Scarborough, Ontario|Scarborough]] for the first time since the completion of [[Line 3 Scarborough]].<ref name="TO-2017-11">{{cite web |date=November 2017 |title=Sheppard East Subway Corridor Secondary Plan |url=https://www.toronto.ca/wp-content/uploads/2017/11/9805-cp-official-plan-SP-9-SheppardEast.pdf |url-status=live |archive-url=https://web.archive.org/web/20210307124632/https://www.toronto.ca/wp-content/uploads/2017/11/9805-cp-official-plan-SP-9-SheppardEast.pdf |archive-date=March 7, 2021 |access-date=February 15, 2021 |publisher=[[Municipal government of Toronto|City of Toronto]] |quote=This secondary plan is based on the following assumptions: a) that a Sheppard Subway has been constructed with stations at Don Mills Road, Leslie Street, Bessarion Road, Bayview Avenue and Yonge Street, and that a future station may be constructed at Willowdale Avenue; and, b) that Sheppard Avenue will be widened to seven lanes from Beecroft Road to Leslie Street}}</ref> In 2015, the TTC estimated that a Sheppard subway to Scarborough Centre would have 7,800 riders per hour while 10,000 per hour was the minimum number of riders per hour considered appropriate for a subway. The maximum capacity of the subway option was about 30,000 riders per hour, approximately the load the Yonge portion of Line 1 carried in the morning rush.<ref name="TorStar20150518" />

In April 2019, the provincial government under Premier Doug Ford announced that it supported an eastward extension of Line 4 but included no promise of funding nor a proposed target date for completion. The province revised the proposed route to terminate and meet a then-proposed [[Scarborough Subway Extension]]<!--Don't bypass redirect per [[WP:NOTBROKEN]]--> of [[Line 2 Bloor–Danforth]] at Sheppard Avenue East and [[McCowan Road]] instead of at Scarborough Centre.<ref name="CBC-2019-04-04"/> The announcement noted that construction of the line would not begin until the 2030s, following the completion of the Scarborough Subway Extension.<ref name="CBC-2019-04-04" /> 

In November 2023, Metrolinx announced preparation of an initial business case for Line 4 extensions as previously supported in April 2019, and that it was also considering a further extension of Line 4 east of McCowan Road to Meadowvale Road as part of the study limits<!--Don't mention the Toronto Zoo despite its proximity-->.<ref name="Metrolinx-2023-11-14" /> In June 2024, Metrolinx held several public consultations with routing concepts.<ref name=":2">{{Cite web |title=Learn more about the Sheppard Subway Extension. |url=https://www.metrolinx.com/en/projects-and-programs/sheppard-extension/events/sheppard-extension-consultations-june-2024 |access-date=2024-12-11 |website=www.metrolinx.com |language=en}}</ref>

===Westward extension===
[[File:Downsview_Station_Bus_Platforms.jpg|thumb|[[Sheppard West station]] would be the western terminus of the proposed extension]]
A separate {{convert|4.5|km|mi|adj=on}} westward extension was proposed to Sheppard West station on Line 1. Lower population density made this expansion a much lower priority than the eastward one, as the minimal increase in ridership was insufficient to justify the costs. The approval of the Spadina subway extension to the [[Vaughan Metropolitan Centre]] in [[Regional Municipality of York|York Region]] renewed interest in this phase, as a subway connection between Sheppard West and Sheppard–Yonge stations would significantly lower commuting times for [[York University]] students, as well as commuters travelling to and from Vaughan Metropolitan Centre. The tunnel from Sheppard–Yonge station to Welbeck Road (one block east of Senlac Road) was built for train storage at the time of original construction.<ref>{{Cite news |last=Kelly |first=Malcolm |date=August 12, 2000 |title=Some call it the 'Subway to nowhere.'

At its February 20, 2020, meeting, the Metrolinx board of directors endorsed a prioritization framework for a proposed frequent rapid transit network that was inclusive of a proposed subway extension from Sheppard–Yonge station to Sheppard West station; with a forecast ridership of 9,800 per hour in 2031 and a proposed line length of {{convert|4.3|km}} along Sheppard Avenue West, the project scored "medium" with a preliminary benefit-cost ratio of 0.26 to 0.35.<ref>{{Cite web |title=Metrolinx Project Prioritization |url=https://www.metrolinx.com/en/regionalplanning/projectevaluation/projectprioritization/project_prioritization.aspx |access-date=November 2, 2022 |website=www.metrolinx.com |archive-date=October 16, 2022 |archive-url=https://web.archive.org/web/20221016091055/https://www.metrolinx.com/en/regionalplanning/projectevaluation/projectprioritization/project_prioritization.aspx |url-status=live}}</ref>

===Political debates and proposals===
Since 2007, there have been a series of political debates and proposals about whether to extend Line 4 east or west, or whether Line 4 should be continued eastwards as a separate light-rail line or as a heavy-rail extension of Line 4. Major political decisions were made only to be later reversed by succeeding governments. The following sections detail the major proposals.

====Transit City====
{{Main|Sheppard East LRT}}
In March 2007, the City of Toronto, under the mayoralty of [[David Miller (Canadian politician)|David Miller]], and the TTC released the [[Transit City]] proposal to begin a new round of transit expansion using [[light rail]] technology on dedicated rights-of-way instead of subway technology. Under this plan, the Sheppard East subway extension had been replaced by a light rail line running from Don Mills Station along Sheppard Avenue East to Meadowvale Road, where it would have met the northern terminus of an extended Line 3 Scarborough. Under this proposal, there would be no direct connection between [[North York City Centre]] and [[Scarborough City Centre]].

====Rob Ford era====
As a result of the election of [[Rob Ford]] as mayor of Toronto in 2010, the western extension of the Sheppard subway to Sheppard West Station and the eastern extension to Scarborough Centre were considered a priority again.<ref>{{cite news |url=https://www.thestar.com/news/transportation/article/899641--war-on-the-car-is-over-ford-moves-transit-underground |location=Toronto |work=The Star |first1=Tess |last1=Kalinowski |first2=David |last2=Rider |title='War on the car is over': Ford moves transit underground |date=December 2, 2010 |access-date=September 3, 2017 |archive-date=October 22, 2012 |archive-url=https://web.archive.org/web/20121022231134/http://www.thestar.com/news/transportation/article/899641--war-on-the-car-is-over-ford-moves-transit-underground |url-status=live}}</ref> He indicated in a December 2010 interview with ''[[The Globe and Mail]]'' that all other transit projects would come second to completing the Sheppard line, stating "I'm just focusing on doing the Sheppard subway underground."<ref>{{cite news |url=https://www.theglobeandmail.com/news/national/toronto/rob-ford-ready-to-let-transit-projects-hold-in-favour-of-sheppard-subway/article1846354/ |location=Toronto |work=The Globe and Mail |title=Search |date=December 21, 2010 |access-date=September 3, 2017 |archive-date=February 10, 2011 |archive-url=https://web.archive.org/web/20110210172519/http://www.theglobeandmail.com/news/national/toronto/rob-ford-ready-to-let-transit-projects-hold-in-favour-of-sheppard-subway/article1846354/ |url-status=live}}</ref>

On March 31, 2011, Rob Ford announced that the proposed Sheppard East LRT line would be replaced by western and eastern extensions for the Sheppard line so that the completed line would run from Sheppard West station to Scarborough Centre. The Ontario government approved this plan, which was estimated to cost $4.2{{nbsp}}billion. The City of Toronto would assume complete financial responsibility for the project, which was proposed to be funded through a [[public–private partnership]], as well as through the use of surplus funds from the proposed Eglinton Crosstown line (later renamed [[Line 5 Eglinton]]), if there were any. Massive redevelopment along the route would be needed to generate these funds, as the then-current population density and projected ridership was too low to support the cost of the expansion by itself.<ref>[[John Lorinc]] and Adrian Morrow, [https://www.theglobeandmail.com/news/national/toronto/toronto-mayor-rob-fords-transit-plan-wins-provincial-approval/article1963854/ "Toronto Mayor Rob Ford's transit plan wins provincial approval"] {{Webarchive|url=https://web.archive.org/web/20110831221915/http://www.theglobeandmail.com/news/national/toronto/toronto-mayor-rob-fords-transit-plan-wins-provincial-approval/article1963854/ |date=August 31, 2011}}.

In 2011, Metrolinx estimated that the westward extension to Sheppard West would be {{Convert|5.45|km|mi|abbr=on}} long, add two stations, and cost $1.48{{nbsp}}billion. The Sheppard East extension would be {{Convert|8|km|mi|abbr=on}} long, add seven stations, and cost $2.75{{nbsp}}billion.<ref>[http://www.metrolinx.com/en/docs/pdf/board_agenda/20110428/Toronto_Transit_Plan.pdf "Metrolinx / Toronto Transit Plan"] {{Webarchive|url=https://web.archive.org/web/20111002152725/http://www.metrolinx.com/en/docs/pdf/board_agenda/20110428/Toronto_Transit_Plan.pdf |date=October 2, 2011}} [[Metrolinx]].

[[Gordon Chong]], head of the TTC agency tasked with analyzing the new subway plans at the time, said it was possible that no new transit development would occur along Sheppard Avenue.<ref>{{cite news |last=Granatstein |first=Rob |title=Rob Ford's Sheppard hole: Granatstein |url=http://www.torontosun.com/comment/columnists/rob_granatstein/2011/04/01/17843306.html |newspaper=Toronto Sun |access-date=April 4, 2011 |archive-date=April 5, 2011 |archive-url=https://web.archive.org/web/20110405000942/http://www.torontosun.com/comment/columnists/rob_granatstein/2011/04/01/17843306.html |url-status=live}}</ref>

====Stintz's alternative====
On January 23, 2012, TTC chair [[Karen Stintz]] suggested a plan to extend the line two stops eastwards funded by making the eastern portion of Line 5 Eglinton at street level.<ref>[http://news.nationalpost.com/posted-toronto/save-money-on-eglinton-lrt-to-extend-sheppard-subway-ttc-chair-suggests "Save money on Eglinton LRT to extend Sheppard subway, TTC chair suggests"].</ref> This motion was defeated by the TTC board. She then got 24 councillors (a majority) to sign a petition calling for a special council meeting for February 8 of that year.

In the meeting, council voted to build the Eglinton project according to the original Transit City plan (partly underground and partly at grade), build [[Line 6 Finch West|an at-grade Finch West LRT]], and to appoint a panel to recommend whether to pursue the eastward extension of the Sheppard subway or construct the Sheppard East LRT instead. The panel reported back to council on March 31, 2012.<ref>{{cite news |last=Kalinowski |first=Tess |title=Special transit meeting: Mayor Rob Ford dismisses council's vote against his subway plan |url=https://www.thestar.com/news/article/1127975--special-transit-meeting-karen-stintz-readies-motion-to-put-lrt-on-finch-and-eglinton-and-strike-panel-to-study-options-on-sheppard |work=[[Toronto Star]] |access-date=February 9, 2012 |date=February 9, 2012 |archive-date=February 10, 2012 |archive-url=https://web.archive.org/web/20120210051839/http://www.thestar.com/news/article/1127975--special-transit-meeting-karen-stintz-readies-motion-to-put-lrt-on-finch-and-eglinton-and-strike-panel-to-study-options-on-sheppard |url-status=live}}</ref> At this council meeting, council approved light rail rather than a subway extension for Sheppard.<ref>{{cite news |url=https://www.thestar.com/news/transportation/article/1150280--will-toronto-s-transit-fight-be-won-today |location=Toronto |work=[[Toronto Star]] |first1=Tess |last1=Kalinowski |first2=David |last2=Rider |title=Rob Ford's subway dream dead as Toronto council votes 24–19 for LRT |date=March 22, 2012 |access-date=September 3, 2017 |archive-date=June 24, 2012 |archive-url=https://web.archive.org/web/20120624064553/http://www.thestar.com/news/transportation/article/1150280--will-toronto-s-transit-fight-be-won-today |url-status=live}}</ref> On April 26 of that year, the motion to build the LRT was announced by the Minister of Transportation after being approved unanimously by [[Metrolinx]].<ref>[http://news.ontario.ca/mto/en/2012/04/ministers-statement-on-toronto-transit-projects.html "Minister's Statement On Toronto Transit Projects"] {{Webarchive|url=https://web.archive.org/web/20140601045835/http://news.ontario.ca/mto/en/2012/04/ministers-statement-on-toronto-transit-projects.html |date=June 1, 2014}}.</ref> The plan still needed to be approved by Ontario's cabinet, though on June 29, 2012, the Board of Directors of Metrolinx unanimously approved the same motion approved by Metrolinx in April.<ref>[http://www.thecrosstown.ca/ "More Transit for Toronto | Crosstown"] {{Webarchive|url=https://web.archive.org/web/20150427051744/http://www.thecrosstown.ca/ |date=April 27, 2015}}.</ref>

====Early Tory era====
During the [[2014 Toronto mayoral election]], incumbent mayor Rob Ford (and his brother [[Doug Ford]], after the prior's withdrawal) were the only major candidates who supported completing Line 4 Sheppard east to McCowan Road (phase-one project) and west to Sheppard West station (phase-two project).<ref>{{cite news |title=Rob Ford unveils subway-heavy transit plan |url=http://www.cbc.ca/news/canada/toronto/rob-ford-unveils-subway-heavy-transit-plan-1.2754039 |work=[[CBC News]] |date=September 3, 2014 |access-date=June 12, 2015 |archive-date=July 3, 2015 |archive-url=https://web.archive.org/web/20150703033039/http://www.cbc.ca/news/canada/toronto/rob-ford-unveils-subway-heavy-transit-plan-1.2754039 |url-status=live}}</ref> [[John Tory]], who won the election, did not include anything on the Sheppard corridor in his maps; instead, he favoured [[SmartTrack]], a proposal to enhance [[GO Transit]] rail service with the city of Toronto.

====Doug Ford era====
In April 2019, Doug Ford, who had since become [[premier of Ontario]] after the [[2018 Ontario general election|2018 provincial election]], unveiled a new transportation plan for Toronto, including the new [[Ontario Line]]<!--Don't give this line a number (tentatively 3) until official sources confirm it with refs added--> to replace the proposed [[Relief Line (Toronto)|Relief Line]], an extension of Line 1 to [[Richmond Hill, Ontario|Richmond Hill]], a northeastward extension of Line 2 with new stations to replace [[Line 3 Scarborough]], a westward extension of Line 5 Eglinton to [[Toronto Pearson International Airport]] in [[Mississauga]] and an extension of Line 4 Sheppard east to [[McCowan Road]], where it would intersect with the Line 2 extension about {{convert|1|km}} north of Scarborough Town Centre. However, money was not set aside in the government's budget for the Line 4 extension.<ref name="Global-2019-04-11">{{cite news |work=Global News |first=Nick |last=Westoll |date=April 11, 2019 |title=Ontario budget 2019: No money for Sheppard line extension, new bridges on Toronto relief line |url=https://globalnews.ca/news/5157545/ontario-budget-says-no-money-for-sheppard-subway-line/ |access-date=August 15, 2019 |archive-date=August 15, 2019 |archive-url=https://web.archive.org/web/20190815165611/https://globalnews.ca/news/5157545/ontario-budget-says-no-money-for-sheppard-subway-line/ |url-status=live}}</ref> During the [[2022 Ontario general election|2022 provincial election]], Doug Ford campaigned for the eastward extension of Line 4 to Scarborough to intersect with the Line 2 extension, as well as for other subway extensions in Toronto.
