The neighbourhood of St. John's that this is in was lower middle class when built. BUT it is VERY close to Wesley United Church. And everything that is not either the church of England or Rome is VERY new to Newfoundland. We were a country divided between Anglicans and Catholics. There was nothing else.
Anyhow, my point is... it is close enough to the church (literally right across the street) that I suspect it was the home of clergy. I bet if I can find a list of the rectors of Wesley United Church, one of them came here from Winnipeg around 1908.
To give you an idea, just about... half a block away from this house and Wesley United, there is St. Patrick's Anglican. And the house next to that, which was build for clergy, looks like this:

While the rest of the street (excluding the Winnipeg house and that one above) looks more like this:

It might not stand out to you in the same way, but to a resident of St. John's, these homes stick out as obviously lower middle class. The slum-style roofs, the lack of bay windows, etc.
So the Winnipeg house, and that other example that I know for a fact was for clergy, are the main nice ones on this street.
