Sienna Senior Living Inc. is one of Canada's largest owners and operators of senior living communities, originally founded in 1972 as Leisureworld Senior Care Corporation. The company operates through two primary segments: Retirement and Long-Term Care (LTC). Its retirement residences, marketed under the Aspira brand, offer independent living, assisted living, and memory care services tailored to private-pay residents. The long-term care segment provides 24-hour nursing and personal care funded partially by provincial governments. With over 90 properties across Ontario, British Columbia, Saskatchewan, and Alberta, Sienna employs thousands of team members to support daily living and health monitoring for seniors. The company distinguishes itself through its hospitality-focused care model and integrated campuses that allow residents to transition between care levels.
