Austin, the graph you are showing hides what may turn out to be ephemeral duration effects. That is turning out to be the case in the US and, now, other first world markets (not Canada's per se). I agree that negative rates can cause price distortions but I'm not wise enough to state this effect is necessarily permanent. A few smart people have told me it's not and while I cannot attribute a 100% certainty to a crash I would not be doing my DD by not taking it under active consideration.
Or stated another way, looking at even, say, 30 years of trend may not be long enough to capture the most probable range for asset price movements. That was certainly the case with Japan, my favourite whipping post. You may be right and Vancouver (and Sydney NSW) are "different", but it's not something into which I for one would devote any additional positions.
