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 La Grande-Trois.
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.

La Grande-Trois is a locality in Eeyou Istchee Baie-James; Nord-du-Québec, Quebec, Canada. It is classified as a village / hamlet. La Grande-Trois is located at 53.7311°N, 75.9792°W.
La Grande-Trois rests in the vast, quiet reach of Eeyou Istchee Baie-James, where the land holds the weight of a northern sky. It lies 107.7 km east of Radisson, QC (from Radisson, QC: bearing 93°T), and is situated 6.7 km east-north-east of Sakami. The terrain around La Grande-Trois is defined by the expansive presence of Réservoir Robert-Bourassa, its waters stretching toward the horizon with a stillness that seems to absorb the very light of the day. Nearby, the rising ground of Colline Masson provides a singular vantage point over the rugged, frost-bitten expanse of the Canadian Shield. La Grande Rivière carves its path through the bedrock, the sound of moving water acting as a constant, low-frequency pulse against the silence of the coniferous woods. During the brief, intense summer, the air carries a sharp, resinous scent of spruce, while the long winters impose a stillness so heavy it feels like a physical presence, turning the landscape into a study of pale light and deep, blue-shadowed snow. The identity of La Grande-Trois is inextricably linked to the harnessing of the northern waters, a history written in the scale of the infrastructure that dominates the horizon. This location serves as an industrial node, shaped by the demands of power generation and the logistical requirements of maintaining such a massive undertaking in the remote north. Life in La Grande-Trois follows the rigorous cycles of the hydroelectric industry, where the expertise of technicians and engineers sustains the flow of energy to the south. Despite the modern machinery, the Indigenous heritage of Eeyou Istchee Baie-James persists as the foundation of the territory, grounding the mechanical intensity of the site within a much older, more enduring sense of place. Even amidst the hum of turbines, the vastness of the surrounding wilderness ensures that the human footprint remains a small, deliberate intervention against the immense scale of the Quebec north.
La Grande-Trois s’élève avec une robustesse tranquille sur les rives de Réservoir Robert-Bourassa, là où le ciel immense du Nord-du-Québec semble descendre pour embrasser la terre. À proximité immédiate de la Colline Masson, le paysage déploie une austérité minérale que seule la lumière changeante du crépuscule parvient à adoucir. Les eaux vastes et profondes de La Grande Rivière dictent le rythme de l’existence, influençant chaque geste quotidien des habitants qui habitent ces étendues marquées par l’énergie et la force brute du territoire. La Grande-Trois observe le passage des éléments, son architecture se fondant dans un décor où le roc et le courant imposent une présence souveraine. Les traditions des peuples de Eeyou Istchee Baie-James imprègnent le quotidien de cette localité, rappelant une alliance ancienne avec un environnement sauvage qui ne se laisse jamais domestiquer tout à fait. Ici, le souffle du vent sur les rives de Réservoir Robert-Bourassa porte une mélancolie légère, presque impalpable, tandis que la Colline Masson veille sur les activités humaines, immuable sentinelle de granit. La Grande-Trois demeure un bastion de détermination, portée par le murmure persistant de La Grande Rivière qui, dans sa course ininterrompue, semble raconter l’histoire inachevée de cette contrée nordique.

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.
