No... The referendum you reference is proposed by he NDP/Greens to be conducted during the province's October 2018 municipal elections.

It is a well known fact that, typically, less than 40% of eligible voters turn out to vote during BC municipal elections...

So, if 50% + 1 vote in favour of the (sure to be self-serving) NDP/Green's proposed new electoral system model, this would mean that the  province's existing electoral system would be chucked in the garbage can- and replaced with another- based upon a "mandate" of 20% of eligible voters voting for this...

Only persons who are corrupt and entirely inappropriate for holding public office would advocate for and or support such a process!!
