Dismissing any critique as just looking through a US lens

Lemme stop you right there. I don’t «dismiss any critique.» I very specifically clarified that my pushback is against a particular Liberal narrative. I’m not here to die on some hill defending Canadian institutions.

Outside of the Liberal narrative, I don't know if we ultimately disagree in any kind of profoundly irreconcilable way. We agree on like 99% of stuff. I have zero debate about your diagnosis of the morbidities of the Canadian system.

But empirically, the claim that «we are moving closer to a structurally codified duopoly» just doesn't hold up. Yes, it is true that our multiparty system does have a narrow overton window of economic policy, but that's not a «structurally codified duopoly». You are describing elite consensus/corporate capture, not duopoly. There is no inexorable march towards a Democrats-vs-Republicans system.

The distinction matters by the way. Because if the problem is a structural duopoly, the solution is mainly electoral-system reform. (And yes, of course I support that.)

But if the problem is a narrow economic Overton window under conditions of corporate power, then PR helps but is not a solution. We also need labour power, movement infrastructure, public-interest media, anti-monopoly policy, campaign finance pressure, tenant organization, public banking, serious tax reform, and parties willing to fight capital rather than merely manage its tantrums.
