It's less multicultural than you expected.
Only about 3% of the population isn't of Irish/English ancestry.
It's just that we're all jumbled together without minority neighbourhoods, and most immigrants tend to live in more urban neighbourhoods near the Old Town core. So, when you're downtown... that 3% looks more like 10% because, of the people who live in/visit the area, they are.
If you go out to the suburbs, which are populated mainly by economically-displaced rural Newfoundlanders, you could be waiting a long time to see anyone who wasn't Irish/English. Out there the 3% feels like 0%.
The only exception is the Muslim community, which has a mosque in the suburbs (Virginia Park) and tends to settle nearby. That community is now large enough that political candidates reach out to them. This year was our first-ever time, in all our centuries of history, that political candidates specifically reached out to Newfoundlanders who belong to a minority. Virginia Park is the dominant neighbourhood of the Virginia Waters provincial district, so if you want to win there, starting this year, you have to do some real politicking. Very exciting!
