==== The 1979 Mississauga train derailment ====
On November 10, 1979, a [[1979 Mississauga train derailment|derailment of a hazardous materials train]] in [[Mississauga, Ontario]], led to the evacuation of 200,000 people; there were no fatalities.<ref>{{cite web|title=Mississauga Train Derailment (1979)|url=http://www.mississauga.ca/portal/residents/localhistory?paf_gear_id=9700018&itemId=5500001|access-date=3 May 2006|work=Local history|publisher=City of Mississauga}}</ref><ref>{{cite web|title=The Mississauga Evacuation, Final Report, November 1981|url=http://cidbimena.desastres.hn/docum/crid/Diciembre2004/pdf/eng/doc4131/doc4131.htm|access-date=21 November 2006|publisher=Ministry of the Solicitor General of Ontario}}</ref> Mississauga Mayor [[Hazel McCallion]] threatened to sue Canadian Pacific for the derailment. Part of the compromise was to accept GO Transit commuter rail service along the Galt Subdivision corridor up to [[Milton, Ontario]]. Limited trains ran along the Milton line on weekdays only. Expansions to [[Cambridge, Ontario]] may be coming in the future.

In 1984, CP Rail commenced construction of the [[Mount Macdonald Tunnel]] to augment the [[Connaught Tunnel (British Columbia)|Connaught Tunnel]] under the [[Selkirk Mountains]]. The first revenue train passed through the tunnel in 1988. At 14.7&nbsp;km (nine miles), it is the longest tunnel in the Americas. During the 1980s, the [[Soo Line Railroad]], in which CP Rail still owned a controlling interest, underwent several changes. It acquired the [[Minneapolis, Northfield and Southern Railway]] in 1982. Then on February 21, 1985, the Soo Line obtained a controlling interest in the bankrupt [[Milwaukee Road]], merging it into its system on January 1, 1986. Also in 1980, Canadian Pacific bought out the controlling interests of the [[Toronto, Hamilton and Buffalo Railway]] (TH&B) from [[Conrail]] and molded it into the Canadian Pacific System, dissolving the TH&B's name from the books in 1985. In 1987, most of CPR's trackage in the [[Great Lakes]] region, including much of the original Soo Line, were spun off into a new railway, the [[Wisconsin Central Ltd.|Wisconsin Central]], which was subsequently purchased by [[Canadian National Railway|CN]]. Influenced by the [[Canada-U.S. Free Trade Agreement]] of 1989, which liberalized trade between the two nations, the CPR's expansion continued during the early 1990s: CP Rail gained full control of the Soo Line in 1990, adding the "System" to the former's name, and bought the [[Delaware and Hudson Railway]] in 1991. These two acquisitions gave CP Rail routes to the major American cities of [[Chicago]] (via the Soo Line and Milwaukee Road as part of its historically logical route) and [[New York City]] (via the D&H).<ref>[http://www.cpr.ca/en/in-your-community/living-near-the-railway/Pages/subsidiaries.aspx Canadian Pacific Subsidiaries website] {{webarchive|url=https://web.archive.org/web/20140416052959/http://www.cpr.ca/en/in-your-community/living-near-the-railway/Pages/subsidiaries.aspx |date=16 April 2014 }}.

During the 1990s, both CP Rail and CN attempted unsuccessfully to buy out the eastern assets of the other, so as to permit further rationalization. In 1996, CP Rail moved its head office from Windsor Station in Montreal to Gulf Canada Square in Calgary and changed its name back to Canadian Pacific Railway.<ref>{{Cite magazine|last=|first=|date=May 1996|title=Branchline Canada's Rail Newsmagazine|url=https://bytownrailwaysociety.ca/phocadownload/branchline/1996/1996-05.pdf |archive-url=https://web.archive.org/web/20190708223210/https://bytownrailwaysociety.ca/phocadownload/branchline/1996/1996-05.pdf |archive-date=2019-07-08 |url-status=live|access-date=27 January 2021|website=[[Bytown Railway Society]]}}</ref>

A new subsidiary company, the [[St. Lawrence and Hudson Railway]], was created to operate its money-losing lines in eastern North America, covering [[Quebec]], Southern and [[Eastern Ontario]], trackage rights to [[Chicago, Illinois]], (on [[Norfolk Southern]] lines from [[Detroit]]) as well as the [[Delaware and Hudson Railway]] in the northeastern United States. However, the new subsidiary, threatened with being sold off and free to innovate, quickly spun off money-losing track to short lines, instituted scheduled freight service, and produced an unexpected turn-around in profitability. On 1 January 2001 the StL&H was formally amalgamated with the CP Rail system.<ref>{{Cite web|url=https://www.cpr.ca/en/investors-site/Lists/FinancialReports/cp-aif-2001.pdf|title=Annual Information Form – Canadian Pacific Railway Limited|date=1 March 2002|website=Cpr/ca|access-date=2020-02-20}}{{Dead link|date=August 2021 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
