Thanks for the replies thus far.
Reading the guide, there are a couple things that stand out.
this is from form IMM5491E
1. Section #18 it mentions that if I am a Canadian citizen living exclusively outside of Canada, I must provide proof that I intend to live in Canada once my common law receives her PR.
2. Section #20 Proof of employment. It says I need to provide a letter from my current employer stating hours of work, how long I've been working there and salary
What does #1 mean, how can I provide proof for this?
