Tilly Rolston (February 23, 1887 – October 12, 1953) was a Canadian politician.
Initially elected to the British Columbia provincial legislature as a Conservative, she crossed the floor and joined W.A.C. Bennett in the British Columbia Social Credit Party before the watershed election in 1952.
She was the second woman to be a cabinet minister in British Columbia, and the first woman in Canada to have a portfolio. In her role as Minister of Education, she introduced a new method of school finance that came to be known as the "Rolston Formula".[1] She was also instrumental in introducing what was effectively a sex-education program into the school curriculum.[2]
She was defeated in the 1953 election by Liberal leader Arthur Laing.
