Canadia is the proper spelling for a country where the people call themselves "Canadians". If the country's name was spelled "Canada," then the people there would call themselves "Canadans." Since they call themselves "Canadians", it's only reasonable to spell the name of their country "Canadia." After all, people from Germany don't call themselves "Germanians" do they?
For those of you who went to public school in the U.S. and haven't heard of Canadia before, it's a small, third-world country just north of the United States. Once you learn to understand their peculiar dialect of English, it's not too hard to converse with Canadian natives.
Canadia is a poor and sparsely-populated country where up to 98% of the citizens are alcoholics. Most Canadian citizens have government jobs where they are paid to say "Eh?" all day long.
