I would like to share my experience at Rainbow bridge yesterday Aug 24. I had gone to Validate my PR procedure on Thursday (Frid,sat,sun,mon.they are not doing any landing procedure as its shows in web ),so i can avoid holidays as they said.The officers at Rainbow bridge said that they have stopped landing procedure for today because heavy rush of tourists from USA . They also said they are not doing landing as their priority any more because of tourist rush, and told me to go back and contact IRCC office . On next day i went to LANSDOWNE in 1000 Island bridge. The officers are so Nice in 5 min I got letter from usa side and once i came back to canada side it took only 10 min .They only asked me to show passport and COPR nothing else they ask .So nice people .I strongly recomend if any one has same issues from any other place they can try this location .
