Since 1985, La Mosaique has positioned itself at the heart of its Longueuil community, and the volunteer center’s thrift boutique is one of the clearest expressions of that long-running mission. Operating as a centre d’action benevole, or volunteer action center, out of 1650 Avenue de l’Eglise, the organization coordinates volunteers across health support, companionship and accompaniment services, aid for low-income residents, social integration programs, and ecological or self-funding initiatives, with the retail boutique feeding directly into that last category. Selling secondhand clothing and household goods lets the organization generate revenue that supports its broader social programming while giving Longueuil residents an affordable place to shop.
The boutique itself keeps a steady weekly schedule, open Tuesday through Saturday from 10 a.m. to 5 p.m., separate from the organization’s administrative office hours of Monday through Thursday from 9 a.m. to noon and 1 to 4:30 p.m., and Friday mornings from 9 a.m. to noon. That distinction matters for anyone planning a visit: the shop welcomes browsers and donors on a near-daily basis even when the front office keeps a lighter, more limited schedule. Beyond retail, the boutique also serves as one of several entry points for community members interested in volunteering, with openings that have included warehouse and stockroom roles alongside customer-facing shifts.
What sets La Mosaique apart from a typical secondhand shop is its institutional backing. The organization is a member of the Federation des centres d’action benevole du Quebec, the provincial network that coordinates volunteer centers across Quebec, which places its Longueuil boutique within a much larger movement of community-based volunteer organizations rather than as a standalone thrift operation. That affiliation also means the shop’s profits are channeled toward a genuinely broad set of services rather than a single cause: health-related support for isolated or vulnerable residents, accompaniment for people navigating difficult life transitions, direct aid for those with limited income, and programs aimed at social integration for newcomers or people re-entering community life after a period of isolation.
La Mosaique also periodically hosts benefit concerts and cultural events, extending its community role beyond retail and direct services into local cultural life, a detail that reflects an organization trying to weave together as many threads of community support as its name suggests. For Longueuil residents, that combination, an accessible thrift boutique paired with health, social, and cultural programming under one volunteer-driven umbrella, gives the shop a different character than a purely transactional secondhand store.
Anyone interested in shopping, donating, or volunteering can reach the organization at 450-465-1803 or by email at info@lamosaique.qc.ca, or visit the boutique directly during its Tuesday-to-Saturday hours at the Avenue de l’Eglise location. In short, La Mosaique’s thrift boutique is a Longueuil fixture that has helped fund four decades of community volunteer work, making every purchase there a small contribution to a much wider network of local social support.
