Replace this archaic institution with a citizens’ senate
While calling for unicameralism would be a mistake – it would reduce the government’s legitimacy due to lack of oversight – the more radical proposal of “abolition” leaves the path clearer toward true structural change that moves beyond tinkering at the edges (such as elected senators).
Why not replace the archaic institution with a citizens’ senate – a rotating group of randomly selected citizens that serve as a house of review? The random group could be stratified, to ensure representativeness of sex, age, race, socio-economic status and regional diversity, matching the makeup of Canadian society.
Granted that this is only an op-ed piece, but I have to admit I am rather amazed that the idea of a sortitionally-selected federal legislature is making it so rapidly into the mainstream.
