I'm trying to figure out how many of the 35 mm by 45 mm pictures I need. The medical office took some there and attached it to the file but I've heard I need 9 total even though the checklist says 2 for US citizens immigrating to Canada. Can some one clarify how many I need not including the medical pictures? I tried to find it on this site but the only things I could find were from more than 5 years ago and I know this new electronic medical system is well new. So if someone could clarify since its 25$ for each set of 2 and that is a lot of money.
