I didn't do much searching (just looked at Amsterdam, really) and I think these buildings might fit in Winnipeg fairly well. If they weren't built in Amsterdam first, of course. No one likes a copycat.
IJ Toren
Viñoly
Mondriaantoren
Rembrandt Tower
Oh, only the last one is taller than CWP but you could stretch them up. They're really just ideas, I'm not saying we should transplant the buildings exactly as they are. Though they'd make amazing filler.
