In Winnipeg, I think it's because the southwestern part of the city and downtown are on the same side of the tracks. It's the same in Regina: downtown is south of the railway. So is Brandon. And Saskatoon. Calgary breaks this trend, but downtown there is positioned between the railway and the river, and their wealthier area on the south side of the tracks is alone a picturesque creek so that was likely a selling point. (Thunder Bay's wealthiest inner-city neighbourhood is north of a downtown core, along a creek.) In Edmonton it looks like the wealthy areas are east and west of downtown along the river (prime real estate because of views and proximity to downtown), and the railway approaches from the south.
