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 Castonguay.
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.

Castonguay is a residential area in Amqui; La Matapédia, Quebec, Canada. It is classified as a small locality. Castonguay is located at 48.4542°N, 67.4350°W.
Castonguay rests in a hollow of stillness, defined by the persistent, cold vitality of the Rivière Matapédia as it carves through the quietude of the land. Near the Cap Pioui, the earth rises in sharp, sudden relief, casting long shadows that swallow the sun well before the hour of twilight fully descends. Only a kilometer away, the surface of Lac Castonguay reflects the sky with a mirror-like clarity, holding the stillness of the surrounding woods in its deep, dark water. The air here carries the scent of damp moss and pine, a cool breath that seems to cling to the valley floor, grounding the landscape in a heavy, ancient peace. The life of Castonguay finds its pulse in the seasonal movements of the water and the land, where the economy has long looked toward the timber and the currents of the river for its sustenance. Men and women here understand the weight of the winters and the brief, brilliant rush of spring, a cycle that shapes the character of those who remain close to the earth. Eighteen kilometers to the south, the Réserve faunique des Rivières-Matapédia-et-Patapédia marks the boundary of the wild, a vast expanse that keeps the spirit of the backcountry close to the doorstep of every home. In the evenings, the light catches the tops of the trees with a pale, amber glow, marking the transition from the labor of the day to the quiet, domestic warmth of the hearth.
Castonguay s'étire avec une patience minérale sur les rives de la Rivière Matapédia, là où le courant semble ralentir pour observer le passage du jour. À quelques pas du Cap Pioui, la lumière déclinante accroche les reliefs avec une douceur presque liquide, révélant la texture brute des terres qui ont vu naître une lignée de travailleurs acharnés, façonnés par la rigueur du climat et la proximité des forêts. Le Lac Castonguay, situé à une brève distance, conserve dans ses eaux sombres le silence des matins brumeux, tandis que l'horizon se referme sur les silhouettes familières de la Réserve faunique des Rivières-Matapédia-et-Patapédia, étendant son influence sauvage à dix-huit kilomètres de là. Castonguay respire au rythme d'une économie liée à la terre et à l'exploitation forestière, une activité silencieuse qui marque les visages et les mains de ceux qui habitent ces parages. Les vents, chargés d'une humidité venue des terres hautes, traversent les champs avec une régularité apaisante, rappelant que la vie ici obéit aux lois anciennes du sol et de l'eau. Chaque demeure, isolée par la vaste étendue, semble veiller sur le passage des heures dans une quiétude parfaite, loin de l'agitation des grands axes, conservant intacte la dignité des gestes simples et la fierté d'une existence humble, tournée vers la pérennité de ce paysage.
