This interactive map shows the street layout and satellite imagery for Rossmount, Ontario. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture to zoom in and out.
Click ⛶ Fullscreen to expand the map to fill your screen for a larger view. To return to the normal page view, press the Escape key on your keyboard, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).

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 Rossmount.
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.

Rossmount is a locality in Northumberland, Ontario, Canada. It is classified as a village / hamlet. Rossmount is located at 44.0447°N, 78.3083°W.
Rossmount rests upon the quiet contours of Jamieson's Hill, overlooking the expansive, light-catching surface of Rice Lake. It lies 14.6 km north-west of Cobourg, ON (from Cobourg, ON: bearing 308°T), and is situated 6.6 km east-north-east of Port Hope. The land here holds a particular quality of stillness, where the low sun at dusk stretches shadows long across the fields, turning the grasses into burnished gold before the evening mist clings to the water’s edge. This terrain, defined by the steady rise of the hill, creates a vantage point that feels removed from the frantic pace of the wider world, favoring instead the slow observation of weather moving across the open basin. The history of Rossmount reflects the persistence of those who settled this specific rise of land, finding sustenance in the fertile soil that supports local agriculture. While the North Ganaraska River flows through the distance, the life of Rossmount remains centered on the immediate relationship between the residents and the surrounding countryside. Daily existence here follows the seasonal changes of the harvest and the subtle shifts in the air, with the economy rooted in the stewardship of the land and the small, deliberate actions of those who live upon it. A distinctive quietude settles over the landscape when the work of the day concludes, leaving only the sound of the wind moving through the trees that crest Jamieson's Hill.

Live weather conditions and 7-day forecasts — including hourly outlooks — are provided through Open-Meteo, while real-time local and world news feeds help keep the page current. Editorial summaries provide additional local information and context.
Detailed location data for Rossmount includes the postal code (L1A), telephone area code (226, 249, 289, 343, 365, 382, 416, 437, 519, 548, 613, 647, 705, 742, 807, 905). These are among the most commonly searched location details for any Canadian city or town.
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.
Location data for Rossmount is sourced from the Canadian Geographical Names Database (CGN), Natural Resources Canada, and verified by coordinates rather than name matching alone. GPS coordinates, province, administrative location and place type are shown in the information panel above.
