==Deactivation and clean-up==
A controversy also developed between the United States and Canada over the cleanup of deactivated Canadian DEW Line sites. The cleanup is now underway, site by site.<ref>{{cite press release|url=https://www.canada.ca/en/news/archive/2011/01/government-canada-recognizes-successful-completion-contaminated-site-clean-up-ivvavik-national-park.html|title=Government of Canada Recognizes Successful Completion of Contaminated Site Clean-Up in Ivvavik National Park|publisher=Government of Canada|date=26 January 2011|access-date=16 February 2016}}</ref> In assessing the cleanup, new research suggests that off-road vehicles damaged vegetation and organic matter, resulting in the melting of the permafrost, a key component to the [[Hydrology|hydrological]] systems of the areas.<ref name="Lackenbauer, Whitney P 2007">Lackenbauer, Whitney P.

These aspects are claimed to have had a devastating impact on the local native subsistence economies and environment.<ref name="Lackenbauer, Whitney P 2007"/>
