Thanks for the info.
I did just realize that I can file outland from Canada (which is awesome!!)...I just want to time it right so I don't have to leave before my 6 months is up...which would be hard to figure out I think.
Yay! Didn't mean to pry but wanted to make sure you were aware you could be with your loved one and save yourself some time (assuming you are American or visa exempt if you are driving up). On the 6 months, you can file for an extension when your six months are up (if you stayed in Canada for the duration) so you don't need to be so concerned about the timing. You can't work, but you'll likely be done and have your PR before you could even get a work permit at the conclusion of inland step 1.
I guess I can just go up there as a visitor, file my application and, once I receive it, just drive back across the border and turnaround, so I can import the car and "land".
Does this seem reasonable?
Yup. Just make sure you take your B4 at that time too. And that your US insurance has Canadian cover while you are visiting. And, that you have all the proof you'll want with you as well as FBI certificates, etc when you go up there if you haven't filed your application yet.
Also, don't take the visiting part too lightly - you really do need to be visiting (no moving furniture or household goods for now...) There's a good post by GOGOGO on this that search isn't finding just now but is worth you looking for a bit later.
