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 Saint-Louis.
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.

Saint-Louis is a municipality in Saint-Louis; Les Maskoutains, Quebec, Canada. It is classified as a village / hamlet. Saint-Louis is located at 45.8500°N, 72.9833°W.
Saint-Louis rests with a quiet weight against the earth, anchored by the slow, deliberate movement of the Rivière Yamaska. It lies 23.8 km south-south-east of Sorel-Tracy, QC (from Sorel-Tracy, QC: bearing 155°T), and is situated 9.3 km north of Saint-Jude. The land here holds a particular stillness, characterized by the subtle rise and fall of the Coteau de Salvail that shapes the horizons of Saint-Louis. As dusk settles, the light catches the surface of the Rivière Yamaska, turning the water into a dark, polished ribbon that mirrors the cooling sky. This terrain, defined by the proximity of the slope and the river, dictates the pace of the days, where the air feels heavy with the scent of damp soil and the seasonal shifts of the valley. Generations have looked to the fertile ground surrounding Saint-Louis to sustain the local economy, keeping the focus sharp on agricultural traditions that anchor the region. Life in Saint-Louis follows the seasonal demands of the harvest, a cycle that remains visible in the quiet industry of the barns and the orderly lines of the fields stretching toward the Coteau de Salvail. The connection to the Rivière Yamaska serves as a constant, historical pulse for the locality, providing a reliable boundary that has guided the development of the land since its earliest days. Neighbors move through the day with a focused intent, their lives shaped by the practical demands of the earth and the enduring presence of the water nearby.
Saint-Louis s'étire avec une patience tranquille sur les terres basses des Maskoutains, là où la terre semble retenir le souffle du jour qui s'éteint. Près du Coteau de Salvail, les champs s'inclinent doucement vers la Rivière Yamaska, dont le cours sinueux sculpte le paysage avec une lenteur presque minérale. Ici, la lumière du crépuscule se dépose sur les sillons agricoles comme une poussière d'or, soulignant la rigueur des labours qui ont bâti la subsistance des familles depuis les premiers défrichements. Saint-Louis vit au rythme de cette terre grasse, une étendue où le ciel, vaste et changeant, semble toucher les rangs de cultures. Les habitations se groupent avec une simplicité modeste, tournées vers le passage de l'eau qui charrie les souvenirs de la vallée. Le silence y possède une épaisseur particulière, celle des plaines qui ont appris à attendre les récoltes et les hivers. L'existence s'écoule sans fracas, portée par une mémoire collective attachée aux cycles du sol et au courant de la Rivière Yamaska, tandis que le relief discret du Coteau de Salvail protège les foyers des vents qui balayent les vastes horizons de cette portion du Québec.

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.
