Maybe 1 in 100 000 application; I am a canadian and I am sponsoring my husband, he has got the PR just waiting for the passport to be picked up.., I have an immigration lawyer in Canada, and they said in their 16 years of experience with IRCC they have never heard of a Permanent Residence being given on the spot the day of the interview, so far all the advice my lawyer has given us in the last 8 months has been 100% accurate, Permanent Residence is not jus a stamp Visa on your passport, please contact IRCC, or believe what you want , I am only telling you that it is a difference between just a visa and a process of becoming a permanent resident of Canada including the counterfoil your passport which must likely isn't done in one or 2 hours.
