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 Mission-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.

Mission-Saint-Louis is a locality in Carleton-sur-Mer; Avignon, Quebec, Canada. It is classified as a village / hamlet. Mission-Saint-Louis is located at 48.1758°N, 66.2597°W.
Mission-Saint-Louis rests quietly along the shore of the St. Lawrence, where the land rises toward the prominence of La Butte and the Ruisseau Samuel cuts a persistent path through the terrain. It lies 14.9 km north-east of Baie-des-Hérons, QC (from Baie-des-Hérons, QC: bearing 35°T), and is situated 14.9 km north-east of Heron Bay. The air here carries a sharp, saline clarity, a crispness that lingers even as the afternoon light softens into the pale, bruised purples of a maritime dusk. Beyond the immediate coastal reach, the landscape shifts toward the interior, where the stillness of Lac Gallant sits four kilometers inland, and the dramatic descent of Chutes de Brébeuf reveals itself ten kilometers away. The horizon feels vast and open, anchored by the geological weight of the earth and the constant, rhythmic pulse of the tides that shape the shoreline of Mission-Saint-Louis. Daily life in Mission-Saint-Louis remains closely aligned with the seasonal turns of the coast, reflecting a history rooted in the hard-won traditions of the Gaspé Peninsula. While the regional economy has long looked toward the water and the timbered slopes, the presence of Parc national de Miguasha just eleven kilometers away serves as a reminder of the ancient, fossilized life preserved within these cliffs. The people here move with the deliberate focus of those who understand the temperamental nature of the St. Lawrence, balancing the demands of modern work with a deep, inherited respect for the surrounding topography. Whether tending to the small parcels of land near the Ruisseau Samuel or navigating the coastal roads, the residents maintain a quiet tenacity that matches the rugged, enduring character of their environment.
Mission-Saint-Louis se déploie avec une grâce tranquille sur les rives du Saint-Laurent, là où l’air marin imprègne le sol de sa fraîcheur iodée. Près de La Butte, le terrain s’incline doucement vers les eaux limpides du Ruisseau Samuel, dont le murmure accompagne le rythme des jours dans cette portion de Carleton-sur-Mer. Le paysage se décline en une succession de douceurs géographiques, marquées par la proximité du Lac Gallant qui repose à quatre kilomètres de là, comme un miroir posé sur les terres intérieures. Plus loin, la topographie s’anime davantage avec les Chutes de Brébeuf, situées à dix kilomètres, et le Parc national de Miguasha, distant d’environ onze kilomètres, qui rappellent les strates anciennes de la terre. Le quotidien à Mission-Saint-Louis s'étire dans une atmosphère empreinte d'une simplicité laborieuse, fidèle aux traditions agricoles et maritimes qui ont façonné cette contrée. Au crépuscule, lorsque la lumière décline sur le Saint-Laurent, le calme s'installe sur les rives, révélant une beauté austère et familière. Mission-Saint-Louis demeure un espace de sérénité, où la géographie impose sa propre mesure aux gestes des habitants, entre la rigueur du climat et le mouvement perpétuel des marées qui baignent les côtes.

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.
