About the Riding
Kingston's economy is anchored by three major institutional employers: Queen's University with roughly 9,350 employees, Kingston Health Sciences Centre with approximately 5,950 staff, and Canadian Forces Base Kingston with about 5,800 military and civilian personnel. Together these institutions account for a substantial share of local employment, giving Kingston a distinctive public-sector and knowledge-economy character. The Royal Military College of Canada, St. Lawrence College, and the Correctional Service of Canada also maintain a significant presence.
The city's heritage architecture, limestone buildings, and waterfront location support a vibrant tourism sector, with the Thousand Islands region to the east and Prince Edward County to the west drawing visitors year-round. The downtown core features a mix of restaurants, boutiques, and cultural institutions including the Grand Theatre and the Agnes Etherington Art Centre.
In 2021, housing affordability and the cost of living were top concerns, driven in part by rising real estate prices in a city with a constrained land base. The student population from Queen's University and St. Lawrence College shapes neighbourhood dynamics, particularly in the downtown core and Sydenham ward. Healthcare access, including emergency-room overcrowding at Kingston General Hospital, was a persistent issue.
The riding's island communities face their own set of challenges, including ferry service reliability and costs, limited infrastructure, and the effects of climate change on water levels and shoreline erosion. Kingston and the Islands has returned Liberal members to Parliament in most recent elections, reflecting a riding where education, healthcare, and institutional employment tend to shape political preferences.
