TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the Canada Base Map from Natural Resources Canada with Toporama contours layered over it — the CanVec topographic data behind the printed NTS sheets, and the mapping used for hiking, hunting, canoe routes and back-country travel. Relief shows shaded relief and hypsometric tints. The search box finds any Canadian town, county or landmark by name, so you are not limited to Le Grand-Boisé.
Reading the map like a paper NTS sheet. Click Grid to overlay the UTM grid, labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass — which matters in Canada, where declination runs from about 20 degrees west in Newfoundland to 20 degrees east in the Yukon.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a UTM/MGRS grid reference as well as plain latitude and longitude — the grid reference being what Canadian search and rescue work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.
Map search is available for a limited number of queries per session to manage costs. Be specific — search precisely for best results.

Le Grand-Boisé is a residential area in La Prairie; Roussillon, Quebec, Canada. It is classified as a small locality. Le Grand-Boisé is located at 45.4000°N, 73.4742°W.
Le Grand-Boisé rests as a quiet reach of land near the Le Coteau, defined by the low, steady pulse of the Rivière Saint-Jacques as it winds toward the larger expanse of the St. Lawrence. It lies 13.6 km south-south-east of Montréal, QC (from Montréal, QC: bearing 153°T), and is situated 13.1 km south-south-west of Longueuil. The terrain here holds a particular stillness, where the light at dusk catches the damp edges of the soil, turning the grasses a bruised, metallic gold before the shadows lengthen. This is a landscape of transition, where the heavy, humid air of the river valley settles early, cooling the fields and pressing against the edges of the woods. Further afield, the presence of Lac de l'Île Notre-Dame sits 12 km away, while the distant rise of Parc national du Mont-Saint-Bruno marks the horizon at 21 km, framing the local view with a subtle, distant permanence. Life in Le Grand-Boisé carries the weight of a long agricultural past, shifting now into the quiet efficiency of modern La Prairie. Generations have worked this Roussillon earth, finding a stubborn fertility in the silt deposited by the Rivière Saint-Jacques, a waterway that serves as both a drain for the fields and a memory of the early settlers who first cleared the brush. The economy here moves with the deliberate pace of those who know the land, balancing the demands of a growing region with the lingering habit of tending to one’s own patch of ground. Whether through the seasonal maintenance of property or the steady transit of people toward the St. Lawrence, Le Grand-Boisé maintains a character that values the tangible over the fleeting, grounded firmly in a geography that has seen the slow, patient clearing of the woods and the eventual return of the wild to the margins of the town.
Le Grand-Boisé déploie ses frondaisons sur les rives du Saint-Laurent, là où l'air chargé d'humidité semble suspendre le mouvement des heures. À proximité du Coteau, le terrain s'incline doucement vers la Rivière Saint-Jacques, dont les eaux calmes serpentent entre les terres cultivées et les zones résidentielles, rappelant la patience nécessaire aux anciens défricheurs de ces sols argileux. La lumière du crépuscule, déclinant sur les plaines de La Prairie, baigne Le Grand-Boisé d'une clarté dorée qui accentue la droiture des arbres et la rectitude des chemins. Au loin, le souvenir des terres plus lointaines se devine par la présence, à douze kilomètres, du Lac de l'Île Notre-Dame, tandis que le Parc national du Mont-Saint-Bruno, situé à vingt et un kilomètres, offre une silhouette bleutée aux confins de l'horizon. Les habitants vivent ici dans une intimité discrète avec le fleuve, un voisinage qui dicte, par ses marées et ses souffles, le rythme des jours. Dans ce silence particulier de la plaine, l'héritage agricole se transmute en une quiétude moderne, où le sol, autrefois tourné vers la subsistance, porte désormais les traces d'une vie quotidienne attentive aux moindres variations de la saison, entre la terre ferme et la mouvance incessante des eaux.

Search Maps opens a second, independent map. It searches OpenStreetMap for any Canadian town, county or landmark by name; offers the Canada Base Map with Toporama contours and shaded relief as base layers; overlays a labelled UTM grid so the map can be read like a printed NTS sheet; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a UTM/MGRS grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data for Le Grand-Boisé is sourced from the Canadian Geographical Names Database (CGN), Natural Resources Canada, and verified by coordinates rather than name matching alone. GPS coordinates, province, administrative location and place type are shown in the information panel above.
