i read long time ago that you should dress as if you are going to a job interview. This gives the impression that the person can adapt to job interviews in Canada. This was one person's opinion based on what his IO told him (i think). I don't think there is any standard dress code but be safe and go as if you are going for an interview.
hi, interesting question and I would like to agree with rupesh.Would u plz like to reveal what were the reasons in ur view for which u were called for an interview as it could help many.Good luck
