I brought them during my landing but the CBSA officer only asked for the landing paper and passport. The two families in front of me had to show bank statements, parents job offer, and kids school enrollment letter thou. And then different applicants, the two females on another line were missing a single document and were stuck there for at least half an hour.
Thanks this was helpful
It maybe better to come prepared than being sorry. Pretty much you are helping them to help yourself! Good luck...
