A Liberal-Labour Lady restores British Columbia’s first female MLA and the British Empire and Commonwealth’s first female cabinet minister to history. An imperial settler, liberal-labour activist, and mainstream suffragist, Mary Ellen Smith demanded a fair deal for “deserving” British women and men in the late nineteenth and early twentieth centuries. Born in England in 1863, the daughter and wife of miners, she emigrated to Nanaimo, BC, in 1892. As she became a well-known suffragist and her husband Ralph won provincial and federal elections, the power couple strove to shift Liberal parties leftward to benefit women and workers, while still embracing global assumptions of British racial superiority and bourgeois feminism’s privileging of white women. Ralph’s 1917 death launched Mary Ellen as a candidate in a tumultuous 1918 Vancouver by-election. In the BC legislature until 1928, Smith campaigned for better wages, mothers’ and old age pensions, and greater justice, even as she endorsed anti-Asian, settler, and pro-eugenic policies. Her death in 1933 ended an experiment in extending democracy that was both brave and deeply flawed. A Liberal-Labour Lady sheds light on a Canadian suffragist undeservedly neglected by scholars and forgotten by posterity. It also illuminates a half a century of political history, first-wave feminism, immigration, and labour history set in a broad context of shifting ideas, ideologies, and strategies. Although simultaneously intrepid and flawed, Mary Ellen Smith is revealed to be a key figure in early Canada’s compromised struggle for greater justice, who helped set the contours of a modern Canada.
