I've actually been wondering where they would switch the names from Fort York to Bremner. Thanks for the information.
I definitely get where you're coming from about the great river effect, but I live just north of the railway tracks and it's a real inexplicable psychological barrier. I will happily walk twice as far north into the city as I will walk south across the tracks. A walk up to Queen is pleasant while the walk down to Bremner, half the distance, is an ordeal. It doesn't really make sense, but other people who come to visit me have said the exact same thing and it's even more extreme for them than it is for me. Maybe as the whole area is built out, it will feel like more a part of the city.
