nope,,,in toronto,,montreal,,and ottawa all the staff at the cuban consulate and embassy are CUBANS..
if i was canadian though,,I would get into the embassy in havana,,,maybe its because You guys are too nice and polite(i mean this as a compliment)
if you screamed and pushed into the embassy of course you would get in(the cuban way) but they know canadians dont do that and a simple no is enough....
no matter where you are,,,if you seek info at your embassy THEY have to let you in....
another easier option is to say you did something bad or that you lost your passport
they WOULD have to let you in
