Thank you so much for your efforts to let me know your experience and what you did. I think it is better to be overly cautious rather than sorry. I am planning to make the SIN card and now I wonder if I should reconsider it. I have not read anywhere that SIN card can be considered a primary or secondary tie to Canada.I've been in a similar situation. When I landed with COPR docs, I made it clear to immigration that I was doing a soft landing, and that my move date would be later. I also provided a list of all items that I would be moving at a later date - it's important to provide such a list when you land on Oct 2022 or you may be liable for duty when you do move. My PR status became official during my soft landing and I received paper-work as such, and I provided my sister's address in Canada for mailing the PR card.
Besides that, I've gone out of my way to NOT create further ties with Canada until our official move. So, I did NOT apply for a SIN card, nor a bank account, drivers license or anything else. Not sure if I'm being overly cautious.
Also not sure what you should do about your Canadian drivers license or bank account. But surrendering/closing them would be evidence that you did not consider yourself a resident until your official move.
Reading online, now I regret that my immigration lawyer advised me to go for the Quebec Investor program. It seems so different from all the other provincial and federal program. I wish I could change it...(wishful thinking).
