I just sent it back with a cover letter, AND included their Alberta Healthcare cards. They do not give a list of exactly WHICH forms of ID they accept - just that it needs to be at least 2 forms of ID, and both have to have their dates of birth on it, and one has to at least have a photo.
So I figured a copy of Passport (with photo and date of birth), a copy of PR Card (also with photo and date of birth) and a birth certificate which has date of birth on it will be sufficient - 3 forms of ID..... I think it was an oversight, but puts me back in the bottom of the pile again, and another $80 wasted.
