La Société immobilière Marc Lemieux (SIML) is advancing its long‑term strategy for seniors’ housing with the acquisition of three retirement residences in the Québec City region. The recent transaction, valued at $51 million, adds 436 units to its growing portfolio and reinforces its commitment to safe, dignified, and community‑centred living environments for older adults.
For SIML, the announcement represents both a strategic expansion and a deepened investment in the long‑term stability of Québec’s seniors’ housing sector.
“A seniors’ residence is first and foremost a living environment where everyone should feel at home, safe, and respected, and it is with this mindset that we begin this new chapter,” said Marc Lemieux, President of SIML. “As the market continues to evolve, we aim to contribute to a stronger and more sustainable ecosystem by investing in quality residences, supporting trusted operating partners, and helping create environments where residents can live with dignity, safety, and a genuine sense of belonging.”
The three properties—Pavillon Sekoïa in Lévis, Pavillon au Cœur du Bourg in Charlesbourg, and Pavillon de Claire in Vanier—were previously operated by LOGISCO and employ about 140 people. Michel Parent, President of LOGISCO, said the decision to sell was not easy, but added, “We are confident that SIML and Groupe Patrimoine will continue to build on what has made these communities successful.”
All parties have underscored the importance of continuity and partnership throughout the operational transition, emphasizing stability for residents while ensuring the benefits of renewed long‑term investment. Groupe Patrimoine—a Québec family‑owned company with more than 30 years of experience in retirement residence management—has been entrusted with day‑to‑day operations, and will keep existing teams, services, and routines in place while taking time to understand each community’s needs; it also plans to strengthen collaboration among private, public, and community stakeholders, an approach it considers essential to long‑term quality and stability across Québec’s seniors’ housing sector.
“For us, a retirement residence is much more than a building, it’s a home where every resident deserves to be known, respected and supported,” said Nathalie Paré, President and CEO of Groupe Patrimoine. “Our role is to help our communities evolve in line with the needs and expectations of residents and their loved ones, while preserving what makes each one unique.”

Meeting a growing societal need
SIML’s portfolio expansion comes at a time when Canada’s seniors’ housing sector faces mounting pressure, as demand outpaces new developments driven by an aging population and evolving expectations around comfort, care, and community. At the same time, rising construction costs, regulatory complexity, and significant capital requirements have slowed the creation of new residences.
According to Lemieux, many existing properties require modernization to meet updated government standards and support resident well-being.
“SIML sees a very strong long-term outlook for seniors housing in Quebec and Canada,” he said. “The aging population is creating sustained demand for quality housing options that combine comfort, services, care, and community.”
Lemieux added that demographic pressures are particularly acute in Québec, where an aging population is driving additional demand for housing that balances independence with access to services. SIML sees these dynamics as “creating meaningful opportunities for committed owners that prioritize quality, stability, and ongoing modernization.”
He also emphasized the importance of collaboration: “We believe the future of the sector will depend on strong relationships between long-term investors and experienced operators who understand the realities of residents, families, employees, and local communities.”
While the addition of 436 units marks a meaningful expansion for SIML, Lemieux says the company intends to continue growing its seniors’ housing portfolio through additional acquisitions in the years ahead. Its Quebec-based portfolio currently includes nearly 2,000 units across seniors’ residences, hotels, residential properties, and a shopping centre, all supported by more than 275 employees and experienced operational partners.
As Québec’s seniors’ housing sector continues to evolve, SIML’s acquisition of Pavillon Sekoïa, Pavillon au Cœur du Bourg, and Pavillon de Claire signals confidence in the future—and SIML’s belief that long‑term ownership, paired with experienced operators, can help build resilient communities where older adults feel supported, connected, and at home.
