CBSA : Canada Border Services Agency
its random , i have the same case with 2 friends , came at the same to canada , studied the same major finished same time . i applied before them 2 months they got it before me a month and half !
even , since i came to canada i never traveled outside , not even outside quebec . my friends traveled couple times which means should be more security checking for their cases . so to conclude its random depending on the agent that treat you application . i ordered the gcms in the end of feb
