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 Longueuil.
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.

Longueuil is a town in Longueuil; Montérégie, Quebec, Canada. It is classified as a town. Longueuil is located at 45.5139°N, 73.4315°W.
Longueuil occupies a substantial expanse along the southern shore of the St. Lawrence, where the horizon meets the soft, low-lying ridges of the Les Écores. It lies 9.6 km east of Montréal, QC (from Montréal, QC: bearing 87°T), and is situated 10.2 km south of Boucherville. The air here carries a persistent moisture from the river, which at dusk turns the sky into a bruised violet, casting long, contemplative shadows across the flat terrain. Beyond the immediate urban footprint, the land opens toward the distant, preserved quietude of Parc national du Mont-Saint-Bruno, while the subtle flow of the Rivière Sabrevois traces a path through the surrounding plains. Even the light reflecting off the nearby Lac de l'Île Notre-Dame seems to hold a particular, silvered clarity, grounding Longueuil in a landscape that feels simultaneously expansive and deeply settled. The history of Longueuil remains anchored in its origins as a seigneurial estate, a legacy that has evolved into a modern center of aerospace innovation and transit. Longueuil balances these industrial ambitions with a quiet persistence, where the daily movement of commuters and the hum of local enterprise create a steady, industrious pulse. While the memory of its early settlers lingers in the older quarters, the present day is defined by the practicalities of a bustling hub that keeps its gaze fixed on the water. It is a place where the weight of the past sits lightly, allowing the inhabitants to move through their days with a focus on the immediate, tangible needs of a changing world.
Longueuil s’étire avec une patience minérale sur les rives du Saint-Laurent, là où le fleuve impose son rythme souverain aux terres basses et fertiles. Les Écores, ces escarpements naturels, dessinent une frontière protectrice qui sépare les plaines habitées des horizons plus vastes de la Montérégie. À une dizaine de kilomètres, le Parc national du Mont-Saint-Bruno dresse sa masse sombre et boisée, tandis que la Rivière Sabrevois serpente discrètement dans les terres environnantes. Vers l’ouest, le Lac de l’Île Notre-Dame capte les reflets changeants du ciel, offrant aux habitants un miroir calme sous la lumière rasante du crépuscule. L’histoire de Longueuil se lit dans ce sol alluvial, autrefois marqué par les sillons des premières seigneuries et la présence des nations autochtones qui naviguaient ces courants. Aujourd'hui, l'activité industrielle et technologique insuffle une modernité discrète à ce paysage, transformant les anciens champs en espaces de labeur et de vie. Longueuil conserve cette allure de bourgade tournée vers les eaux, où l’air garde toujours une fraîcheur venue du large, rappelant sans cesse que la terre, malgré les constructions et le mouvement des hommes, demeure soumise à la grande respiration du fleuve qui la borde.

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.
