===Pratt & Whitney Canada===
{{main|Pratt & Whitney Canada}}

Pratt & Whitney Canada (PWC), originally Canadian Pratt & Whitney Aircraft Company, and later United Aircraft of Canada, provides a large range of products, including turbofan, turboprop and turboshaft engines targeted for the regional, business, utility and military aircraft and helicopter markets. The company also designs and manufactures engines for auxiliary power units and industrial applications. Its headquarters are located in [[Longueuil]], [[Quebec]] (just outside [[Montreal]]).

Speaking to Reuters June 16, 2013, ahead of the Paris Airshow 2013, Pratt & Whitney President David Hess said he was confident that Canada would decide to stick with the F-35 program despite its recent discussions about having a new competition. If the orders did shift to another company, Pratt & Whitney could decide to move some of the industrial base work it is currently doing in Canada, Hess said. "We might reallocate the work elsewhere", he said, adding that reduced order volumes would likely trigger changes in Canada.<ref>{{cite web |url=https://www.cnbc.com/id/100818837 |title=AIRSHOW-UPDATE 2-Pratt sees deal for F-35 engines in next 30 days |date=June 16, 2013|url-status=dead |archive-url=https://web.archive.org/web/20130921060826/https://www.cnbc.com/id/100818837 |archive-date=September 21, 2013 |publisher=CNBC |access-date=October 19, 2018}}</ref>

The division admitted in July 2012 to providing engines and engine software for China's first attack helicopter, the [[CAIC Z-10|Z-10]]. This violated U.S. export laws and resulted in a multimillion-dollar fine.<ref>{{cite magazine |last=Toombs |first=Zach |title=Pentagon Contractor Caught Illegally Selling Military Technology to China|magazine=[[The Atlantic]]|url=https://www.theatlantic.com/international/archive/2012/07/pentagon-contractor-caught-illegally-selling-military-technology-to-china/259469/ |date= 6 July 2012}}</ref>
