What do you mean by American artist, if you rap about where you come from and that is Toronto how are you American? Because you release it in the US? Dude had TV shows interviewing him at his mums home in Toronto. And all of his mixtapes were on OVO (or it's previous name ATF, all things fresh). The single with Trey Songz was distributed by Treys label, Warner. There were no big features from Canada, Kardinal Offishall was the only one, and he was on the tape. All his unknown features, producers, rnb singers and shyt were Canadian except Nickelus F. I mean on So Far Gone he had two two songs with Danish or Swedish artists, was he trying to be Scandinavian?
When you googled him, it didn't say Drake is an American rapper. It said Drake is a Canadian artist, based in Toronto, Canada. Staying in hotels in Mississippi, TX, Ga, FL and NY doesn't mean you are from there. I don't know if you followed Drake, but I did and there was no indication that he was "American", besides the rare occasion when he mentioned that his dad was from the south.
What American rapper goes out talking about "I'm trying to get that house in Toronto with pine floors" and shyt like that. Promoting your shyt on the largest market != saying that you are from that market.
