Haha, well, there's lots of landing stories in the thousand-odd pages of posts on this particular thread, but I will do a quick summary of mine, if nobody minds too much. ;D
Aside from the rocky ending to my flight, landing itself was very easy. I had my Goods Accompanying and Goods to Follow (B4/B4A) forms already completed, so getting through Customs was very quick and easy. Even if you/your spouse are only bringing personal goods, you still need to fill the B4 out ahead of time to make it easy for yourself.
Getting through Immigration was also easy, they confirm some details on your Confirmation of Permanent Residence, such as your correct name, address (to send your first PR card) and the names of your dependents (if any). Your IO might also have a quick chat with you about your residency obligation as a PR (730 days out of every rolling 5 years period). I think pretty much every sponsor here is a citizen, so the good news for us is that any time spent out of Canada traveling with our spouses still counts toward the residency obligation.
As for settling in, it is very much a day-to-day process. My husband has let me find my own way on a lot of things, mostly relating to the house and doing things around the house, for other things he has been very much a helping hand as I get used to them. Things such as finding my way around town, getting my SIN, banking, job-hunting, he has had to do a lot of hand-holding there. We have had to be patient with each other for a number of things, because I am used to having to be independent and getting things done even if by trial and error, and he is very much the take-charge type if he sees things not going the way he thinks they should. I have to remind him to back off and let me try, even more than once, and he has to remind me that he is there to help me so sometimes I need to suck it up and ask for his help. It's give and take all the way.
We live in Elliot Lake, northern ON. We celebrated our 2nd anniversary last week, will have been together 3 years come September. As for relationship advice? When you are apart, live like your spouse is right there next to you. Arrange to "do" things together, even things like going out shopping for groceries at the same time, watching the same TV programmes, whatever. When you are together in Canada, remember there's going to be "growing pains", same as in any new phase of life, and be gentle with each other. Communicate your feelings clearly, and listen while the other person does the same.
