OK this is so confusing but let's do it 
I'm filling the form of "Statutory Declaration of Common-Law Union (IMM 5409)" and the thing is, that I'm from Czech Republic (Country 1), my girlfriend from Belgium (Country 2) and we are signing this document in Germany (Country 3). Of course, we are signing it for Canada (Country 4)
How do we fill the application's countries? I'm asking only about first 8 fields.
Thank you!
