In some ridings maybe. But a big problem in ridings out west is that NDP/Green candidates change every cycle meaning that many people are effectively voting based on the party leadership.

Avi Lewis leadership will hopefully attract stronger candidates that also have the conviction to stick around for multiple election cycles.

The other thing is there's next to zero provincial/federal cooperation for NDP/Green/ LPC... but culturally the CPC supports the provincial conservative parties.

The "3rd Party Argument" is an American discussion bleeding north that has little to do with the Canadian political context. Hence why I considering a timewasting generalization.
