Haha, nice!
Mine would read something like:
Dear Canada,
Even though we've never met, I feel I know you already. This is because I love and cherish one of your sons, and daily I hear from him how wonderful you are and how much there is to be learned from you.
You're worried that if I meet you as a visitor, I may never want to leave, even if you ask me to. However, if you would consult with your neighbour to the south, you would hear only good things about my habits as a visitor, and they would even tell you that I am welcome to return to their abode to visit at any time over the next 8 years or so.
However, since you won't let me visit, we have decided to ask for me to remain permanently instead. I realise I'm one of millions, and therefore undeserving of any special attention, but it would be really nice if your employees at least acknowledged that they had received this request of ours, and didn't make us feel like beggars at the door, including your very own son.
Looking forward (in hope) to meeting you soon,
Charlie.
