This article presents evidence concerning women's representation in Canada's provincial legislative assemblies over a 20-year period (1975–1994). Data from 3,755 elections and over 11,000 candidates are analyzed to inspect trends in representation. The authors find there has been a gradual increase in both female candidates and legislators. The New Democratic party has clearly been the leader in putting women on the ballot and into legislatures at the provincial level. In addition, hypotheses are tested to see if there are differences across provinces in parties' willingness to nominate and elect women, and whether women are more likely to be nominated primarily in districts where a party does not expect to win. The study finds that the Atlantic provinces lagged behind the rest of Canada as representation increased markedly everywhere else in the late 1980s and the 1990s. There is also evidence that the major parties nominated female challengers in ridings that were inferior to the ridings where the party's male challengers ran in the mid- to late-1970s. By the mid-1980s, however, evidence that women were treated as sacrificial lambs had disappeared.
