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 Sir-John Lake.
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.

Sir-John Lake is a locality in Lachute; Argenteuil, Quebec, Canada. It is classified as a small locality. Sir-John Lake is located at 45.7167°N, 74.2833°W.
Sir-John Lake rests within the quiet reach of the Mont Green, cradled by a landscape where the air holds a lingering, sharp clarity. It lies 8.0 km north-north-east of Lachute, QC (from Lachute, QC: bearing 32°T), and is situated 10.7 km east-north-east of Brownsburg-Chatham. Beyond the immediate basin, the Rivière du Nord flows with a steady, hushed purpose about 5 km away, while the nearby Lac Sir-John sits only 1 km distant, reflecting the sky like a fallen shard of glass. The terrain here rises in modest, firm swells, defined by the ancient character of the Mont Green that anchors the horizon. As evening descends, the light catches the surface of Sir-John Lake, turning the water into a bruised plum colour that seems to hold the day’s heat long after the sun has slipped behind the trees. The history of this locality reflects a slow, deliberate growth, rooted in the hard-won clarity of the Argenteuil hills. While Parc national d'Oka stands some 33 km away as a reminder of the wider protected wilderness, the life around Sir-John Lake maintains a sense of isolation that favors the small-scale farm and the private woodlot. Local industry has historically looked to the timber and the soil, shaping a character that values resilience over rapid change. In the quiet hours, one might notice the particular, resonant stillness that defines the region, a quality that suggests the land keeps its own counsel, unbothered by the restless pacing of the world beyond the Mont Green.
Sir-John Lake s'étire dans une langueur contemplative sous la lumière changeante du crépuscule, là où les pentes du Mont Green semblent protéger les esprits de cette terre d'Argenteuil. Le paysage se déploie avec une retenue naturelle, offrant aux regards la silhouette sombre des arbres qui se mirent dans les eaux calmes du Lac Sir-John, situé à un jet de pierre. À quelques kilomètres, la Rivière du Nord trace son chemin avec une persistance tranquille, insufflant une fraîcheur vivace qui imprègne l'air, tandis que le Parc national d'Oka, plus lointain, rappelle la vastitude des horizons environnants. Les anciens sentiers forestiers rappellent les modes de vie d'autrefois, où l'agriculture façonnait le quotidien des familles avant que l'industrie ne vienne ponctuer le silence des collines. Sir-John Lake conserve cette atmosphère de quiétude minérale, une présence qui ne demande rien d'autre que d'être observée, loin de l'agitation des grands axes. Chaque souffle de vent porte la mémoire des terres labourées, invitant ceux qui s'y attardent à goûter à la texture granuleuse du sol et à la clarté des eaux dormantes, loin des artifices, dans une simplicité qui définit le caractère singulier de cette contrée québécoise.

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.
