A Quebec political operator who pivoted from the legislature to lead the province's powerful construction industry regulator.
Diane Lemieux carved a path through Quebec's political landscape before stepping into a critical administrative role. Elected to the National Assembly of Quebec in the late 1990s, she served in cabinet positions, handling portfolios like culture and communications and labour. Her political career was marked by a practical, reform-minded approach. After leaving electoral politics, she leveraged her understanding of government and labour dynamics to take the helm of the Commission de la construction du Québec (CCQ) in 2015. As President and CEO, she oversees the body that regulates Quebec's massive construction industry, managing relations between unions and employers and enforcing complex training and competency standards. Her leadership at the CCQ places her at the heart of the province's economic engine, ensuring the stability of a sector fundamental to Quebec's infrastructure.
1946–1964
The largest generation in history at the time. Shaped by postwar prosperity, the Vietnam War, the sexual revolution, and Watergate. They questioned every institution their parents built — then ran them.
Diane was born in 1961, placing them squarely in the Baby Boomers. The events that shaped this generation — postwar prosperity, civil rights, Vietnam, and the counterculture — shaped the world they entered and the choices available to them.
