Border Security: Canada's Front Line is a Canadian reality television series that aired from 2012 to 2014. The series, produced by Force Four Entertainment for National Geographic Channel Canada, is a Canadian adaptation of the Australian reality series Border Security: Australia's Front Line and depicted the work of Canada Border Services Agency officers at airports, land crossings, and international mail centres.

The CBSA described the show as an educational tool to educate audiences about its duties and activities, but the series was controversial during its airing. Critics of the show claimed it was exploitative to film people in vulnerable situations, and that persons being detained by immigration officers could not properly give informed consent to being filmed. Border Security was ultimately cancelled following a ruling by the Privacy Commissioner of Canada that the CBSA had breached the privacy rights of a Mexican construction worker by allowing his interrogation to be filmed.
