Sudbury

Sudbury covers the urban core of the City of Greater Sudbury in northeastern Ontario, a community built on the rim of a 1.85-billion-year-old impact structure that created one of the richest mineral deposits on the planet. The riding takes in the former City of Sudbury, portions of the former towns of Walden and Valley East, and extends south to the Greater Sudbury municipal boundary, where the boreal forest of the Canadian Shield presses in on every side.

Candidates

Paul Lefebvre (Liberal) — The incumbent MP, first elected in 2015. A tax lawyer by profession, Lefebvre earned his law degree from the University of Ottawa and a master's in taxation from the University of Waterloo. He also owned Le5 Communications, a francophone media company that included the radio station Le Loup and Le Voyageur newspaper. He served as Parliamentary Secretary to the Minister of Natural Resources heading into the 2019 campaign.

Beth Mairs (NDP) — A former social worker and the organizer of the Sudbury Indie Cinema Co-Op. Mairs focused her campaign on residents with household incomes under fifty thousand dollars, emphasizing inadequate housing, low wages, and the need for a stronger social safety net.

Pierre St-Amant (Conservative) — A retired major in the Canadian Armed Forces who grew up bilingual in the Eastern Townships of Quebec. St-Amant's military career included United Nations tours in the Middle East and Africa. He described himself as a fiscal conservative.

Bill Crumplin (Green Party) — A professor at Laurentian University who taught in the School of the Environment. Crumplin had moved to Sudbury from Sault Ste. Marie around 2003, and had focused on environmental studies in his academic work. He was making his third run at elected office, having previously run for the provincial Greens in Nickel Belt and as a mayoral candidate in the 2018 Greater Sudbury municipal election.

Sean Paterson ran for the People's Party, Chanel Lalonde for the Animal Protection Party, and Charlene Sylvestre and J. David Popescu ran as Independents.

About the Riding

Mining defines Sudbury. Vale and Glencore—the successors to Inco and Falconbridge—continue to operate mines, smelters, and processing facilities across the basin, and a thriving mining supply and services sector has grown into a global export industry in its own right. By 2019, commodity prices had stabilized from the lows of 2015, but the sector's cyclical nature kept economic diversification at the forefront of political debate.

Sudbury's large Franco-Ontarian community—roughly a quarter of the population reports French as a mother tongue—sustains a vibrant cultural infrastructure, including the Théâtre du Nouvel-Ontario, La Nuit sur l'étang, and Prise de parole publishing house. Laurentian University and Health Sciences North, the regional hospital serving a broad catchment across the northeast, are major employers.

The city has also become an international example of environmental recovery. A sustained regreening program launched in the 1970s to address devastation from decades of smelter emissions has planted millions of trees and restored thousands of hectares of once-barren landscape. Housing, health care access, mining-sector regulation, and francophone institutional support were the central campaign issues in a riding that had swung between the NDP and Liberals in recent elections.
