My guess is the developer behind the high-rise proposal is the same guy who was behind Place Dubrovnik or whatever that condo tower was to be called on Assiniboine ave.
Some of you Winnipeg SSP'ers might recall a condo proposal from a year or two ago to build a new tower along the Assiniboine at the Dubrovnik restaurant site.
It would make sense that the developer would seek out a river lot. Almost every major residential tower in our city is along the river or within a short walking distance from it.
Outside of the Exchange, the waterfront is probably the only part of the downtown suburbanites would ever consider moving to.
