In this paper, we investigate the formation of stable voting blocs on non partisan legislative assemblies, in this case municipal councils in two Alberta cities. We find that while formal non-partisanship may well exist, that does not mean that bloc voting does not occur - quite the opposite. The formation of the blocs, rather than being explained by simple party affiliation is, however, better explained by socio-demographic background characteristics (age, gender, education, occupation, etc.) as potential proxies for interest voting and/or ideology. Implications for other non-partisan voting assemblies (municipal councils, courts, tribunals, and the like) are discussed.
