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 Grande-Île.
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.

Grande-Île is a administrative sector in Salaberry-de-Valleyfield; Beauharnois-Salaberry, Quebec, Canada. It is classified as a small locality. Grande-Île is located at 45.2542°N, 74.1431°W.
Grande-Île stands as a quiet sentinel where the waters of the Rivière Delisle meet the expansive reach of Lac Saint-Louis. The land here carries the weight of the nearby Coteau de la Rivière La Guerre, a modest rise that defines the horizon and anchors the low-lying terrain against the persistent push of the wind. During the amber hours of late afternoon, the light clings to the surface of the river, turning the moving water into a sheet of hammered copper that reflects the enduring patience of the shore. The vegetation leans toward the currents, marking a space where the earth feels soft and receptive, held in a delicate balance between the stillness of the fields and the insistent motion of the inland tides. The history of Grande-Île finds its pulse in the practical movements of those who have long worked these fertile stretches, balancing agricultural tradition with the demands of a modern industrial corridor. While Parc national d'Oka remains a distant silhouette against the sky, the character of Grande-Île is shaped by the immediate proximity of the river and the steady, hum-filled labor of the surrounding industries. Daily life moves with a distinct clarity, defined by the sound of heavy transit and the persistent, low-frequency hum of a region that serves as a vital artery for the broader landscape. Residents move through their chores with a familiarity that suggests a deep understanding of the land, finding beauty in the stark, functional architecture of a place that prioritizes movement and utility over ornamentation.
Grande-Île s’étire avec une patience tranquille sur les rives du Lac Saint-Louis, où les eaux calmes semblent absorber les murmures de la journée. Le terrain plat, façonné par les alluvions et la proximité de la Rivière Delisle, offre un horizon dégagé qui capte les derniers rayons solaires, teintant la terre d'une lumière dorée et hésitante. À quelques encablures, le Coteau de la Rivière La Guerre rappelle les humeurs anciennes des terres agricoles, tandis que le Parc national d'Oka, bien que distant, dessine une silhouette familière dans la brume lointaine du nord. Les résidents de Grande-Île vivent au rythme lent de ces courants qui bordent leurs habitations, un voisinage humide qui dicte depuis toujours le caractère des lieux. Les activités humaines, tournées vers le maintien des rives et la gestion des terres fertiles, s'harmonisent avec le passage des saisons, sans jamais brusquer le silence qui règne entre la Rivière Delisle et les vastes étendues du Lac Saint-Louis. Chaque demeure semble guetter l'arrivée du crépuscule, ce moment précis où le ciel se confond avec l'étendue liquide, offrant aux habitants une quiétude rare dans la région de Beauharnois-Salaberry.

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.
