Abstract: | Based on work by Moon and Sayers on the assignment of ministerial portfolios in Australia, we use a new dataset on portfolio adoption across all ten Canadian provinces and the federal government from 1867–2012. This data set when analyzed shows four distinct patterns of portfolio adoption that point to key motivations behind the development of new portfolios. We show that much of the common wisdom fails to explain portfolio creation but that patterns of development may be better explained by a new typology. The work attempts to fill a gap in the understudied area of Canadian ministerial portfolios and comparative provincial politics. |
