Vancouver urban area (urban area includes Surrey, Burnaby, Richmond etc) is 2.5 million. Your 700K is likely only the city of Vancouver itself, not the whole urban area.
Without the "as an aspiring painter", the future dictator who lived in Vienna could also have been Stalin or Tito. They even lived there at the same time and regularly frequented the famous coffeehouse Cafe Central, together with Trotzky, Freud and others. To imagine they might have sat there playing chess and sipping coffee together...
Guessed Vancouver - but its urban population is less than 700k, so much lower than Vienna at about 1.9 million!
