Where is River Creek? Did you mean False Creek? It was all industrial until the 90s and is now one of the most desirable areas in Canada. The north side (Pacific and Davie) is the epicentre.
One brownfield still in development that no one else will probably mention is in my avatar, the Pier/Shipyards in North Vancouver (Lonsdale ave and Esplanade). Easily accessible from downtown by public transit. If you go on Fridays during the summer it looks like this

Plus a nice view back towards downtown

The area is older than Vancouver itself - formerly known as Moodyville. Still has active shipbuilding yards and tugboat ports beside it.
Gastown (Water St) is the historical area downtown and very trendy right now. Check out the Woodwards complex (West Hastings St and Abbott).
Also the Olympic Village on Southeast False Creek (Athletes Way and Manitoba) changed an industrial area to beautiful mid-rise neighbourhood in under three years.
In general we don't have much brownfield development though because port land is still very viable.
