To be honest, I don’t quite understand it, but…

With Duverger’s Law (i.e., in non-PR electoral systems, a trend towards a two-parties), we are running out of time to act. Canada’s 2021 effective number of parties is 2.76 - this number will decrease over time, and will eventually end Canadian democracy as we know it today.

And we know that proportional representation increases the effective number of parties beyond just 2! Just as a healthy democracy requires!
