Sainte-Marthe-sur-le-Lac, Quebec: History, Things to Do and Travel Guide
Sainte-Marthe-sur-le-Lac sits along the north shore of Lac des Deux Montagnes, west of Montreal and close to the Oka and Deux-Montagnes corridor. Its name tells the first travel clue: water, shoreline and lowland streets are central to how the city developed.
This is a residential lakeside community with quieter, practical appeal: local parks, a municipal beach, water views, neighbourhood services and easy access to other North Shore destinations.
How Sainte-Marthe-sur-le-Lac Started
The area began as a rural lakeside settlement tied to agriculture, parish life and the movement of people around Lac des Deux Montagnes. The Sainte-Marthe name was already attached to the local parish landscape before the modern city took shape. Quebec’s toponymy records the name and the lakefront setting that define the municipality.
For much of its early life, Sainte-Marthe-sur-le-Lac was small and partly seasonal. Families used the shoreline for cottages and summer stays, while farms and country roads still shaped the backland. Its location between the lake and the growing Montreal North Shore made it attractive as road access improved and suburban growth pushed west.
The municipality was incorporated in the twentieth century and later became a city. Growth changed the local pattern from scattered rural and seasonal properties to permanent neighbourhoods. Flooding has also shaped local memory and planning, especially along the lake edge, where water levels and shoreline protection remain part of civic life.
The city’s lake relationship has always been practical as well as scenic. The water drew seasonal residents and recreation, but it also required decisions about shore protection, drainage and public access. That tension is part of the modern city. Sainte-Marthe-sur-le-Lac is pleasant to visit when the lake is calm, yet it is also a place where residents understand that shoreline living needs planning and upkeep.
What Sainte-Marthe-sur-le-Lac Is Like Today
Sainte-Marthe-sur-le-Lac is now a compact city in the Deux-Montagnes RCM. Residential streets, schools, recreation sites, parks and shoreline access define daily life. It sits close to Route 344, commuter routes and neighbouring North Shore communities, so many visitors arrive while moving through the wider Montreal-to-Laurentides corridor.
The city feels local and lived-in. Its travel value comes from the lakefront, the municipal beach season, neighbourhood parks and its position near Oka, Deux-Montagnes and Saint-Eustache. Visitors should expect a community with civic facilities and water access, with the lake doing most of the visitor work.
Things to Do and Places Nearby
Plage municipale de la Sablière is the clearest warm-season stop. The municipal beach gives Sainte-Marthe-sur-le-Lac a direct relationship with Lac des Deux Montagnes and is the place most visitors will look for first when planning time by the water. Check municipal information before going, since access, hours and rules can change by season.
The park network is useful for a slower visit. Local green spaces and play areas support short walks, family stops and breaks from driving. They also show the city as residents use it: small-scale recreation, sports fields, paths and lake-influenced neighbourhoods.
The surrounding area adds range without taking focus away from Sainte-Marthe-sur-le-Lac. Oka is close for parkland and historic landscape, Saint-Eustache has older streets and services, and Deux-Montagnes connects the lake corridor to commuter routes. Use those places to round out a day, but keep the Sainte-Marthe stop anchored in its shoreline and parks.

Travel Notes
Summer is the easiest season for travellers because the beach and parks carry more of the experience. Spring can bring changing lake conditions, so checking municipal notices is sensible before planning shoreline time.
A simple route works well: begin with the municipal beach area, continue through nearby parks, then follow Route 344 to understand how closely the community sits between the lake and the North Shore road network. Travellers interested in local history should look for the contrast between the older lakeside pattern and the newer residential streets that grew as the area became a year-round city.
A car makes movement simple, although local walking works once you are near the beach or park areas. Sainte-Marthe-sur-le-Lac is best planned as a focused lakefront stop with enough time for a swim, a walk or a meal nearby, then a short drive through the surrounding Laurentides and North Shore communities. Beach rules, parking and water-quality notices should be checked close to departure in warm weather, especially after heavy rain or extended heat. Late-day lake views can be pleasant even when swimming is not the plan.
