Thank you! PA just landed yesterday, went so smoothly less than 10 minutes with the immigration officer and 5 minutes for customs. The IO didn't ask any questions, incredibly friendly, just handed the CoPR documents and done. As others have said, just organize the B4 forms and your self-made lists, they love it when its organized. And voila, welcome to Canada.
Now border crossing left for the dependents, looking forward to a day of shopping in the States.
Hope good news can follow for others, it's a hell of a journey but that's life.
