@izzythepush,
I reply, "The US," and give them time to figure me out.
The only dicey time I ever had while doing some periodic work in Montreal was when a US home team playing a Canadian team, booed the Canadian anthem.
In contrast to a game where during the US Anthem, the power went off and the Canadian home audience sang the US anthem a cappella.
I love Canada and I would love to be able to live Montreal as opposed to Texas.
All the lyrics of "Oh Canada" I know is: oh Canada. I do recognize the tune and can hum it. I can sorta read French, I'm well past speaking it. I liked Moncton, too.
