Vancouver real estate prices jumped 20% in 2015 -- a $200k gain on a $1M house. If pricing trends continue along that trajectory then Vancouver real estate still looks like a great investment even if you just eat the entire tax.
Still, I'm impressed by how quickly Vancouver is moving forward with these measures (going into effect Jan 1st!). They're sorely needed, and it's great that they don't have to sit in limbo for years before being enacted.
