outland.
go to cic website for all the forms/documents required. there is also a thread here specifically for US Outland applications.
overall cost is $1050 CDN, payable online through CIC website. Timeline for normal cases seems to range from 5-7 months. Some have taken a little longer. You are able to stay in Canada as a visitor while you wait, but you will need to disclose everything to the border guards when you cross. You will need to go inside and speak with one and it is important you have proofs of funds for supporting yourself without working, etc.
I was given a 1 year Temporary Visitor Record (TVR) when I came across. I had the application complete ready to mail and proof of funds so they knew I wouldn't work. Your spouse should accompany you to the border so the agent can speak with him/her as well.
Again, loads of info here in other threads and also at the CIC website
