Nagz , usualy what happen to us is even if you beg them for the visa same day they probably will tell come back tomorow at 2:30 pm, we tried but didnt work on the same day.
for info about when ur husband land in Quebec, typical regular questions, like where u will be living, planning to work?, open a business, need info session for QC , french courses,
nothing unusual , just tell him to be calm and not lose his patience, since lot of questions are just to intimidate ..
hope this helps
inshalah byousal bi salameh and hope u enjoy life here
mabrouk again
