Operation Reassurance (OpRe) is an initiative of the Canadian Armed Forces (CAF) which dates from 2014, when NATO partners "agreed upon and began to enact a series of military measures on 16 April 2014",[1] in response to the February 2014 annexation of Crimea by the Russian Federation. The initial financial commitment was agreed to at a meeting of the Harper Cabinet the next day.[1][2] As of 25 March 2022 it funds the deployment of approximately 1,375 CAF members.[1]
