Reasons for Judgment — McLachlin C.J. (Abella, Moldaver, Karakatsanis, Gascon, Côté and Brown JJ. concurring)
On the correct application of the legal principles to the facts found by the trial judge, it is an inescapable conclusion that the respondents aided and abetted the offence of trafficking through distribution. Their acts prevented or hindered interference with the accomplishment of a criminal act. In this way, the respondents provided assistance and encouragement to Mr. Caines in the commission of the offence of trafficking. There is a clear link between the respondents’ acts and the commission of the offence. [para. 15]
