This interactive map shows the street layout and satellite imagery for Treadwell, 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 Treadwell.
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.

It lies 31.8 km west of Hawkesbury, ON (from Hawkesbury, ON: bearing 268°T), and is situated 8.1 km south-west of Montebello. The air here holds a particular clarity, especially at dusk when the fading light catches the stillness of Lac Georges, located about 3 km away, turning the water into a dark mirror for the sky. The terrain transitions with a subtle grace toward the South Nation River, which runs about 5 km away, its movement marking a slow, steady pulse against the earth. Within a 10 km radius, the natural landscape opens to include the expanse of Parc national de Plaisance, while the distant, rushing energy of Chutes du Portage, situated about 8 km away, offers a reminder of the water’s persistent work across the geology of the region. The history of Treadwell reflects a long association with the agricultural rhythms of the surrounding soil, where the labor of generations has defined the local identity. Economic life in Treadwell continues to draw from these deep roots, favoring a pace that prioritizes the seasonal shifts of the harvest and the maintenance of the homestead. The character of the people is marked by a deliberate focus on the land, a trait that persists despite the changing demands of the modern world. Life in Treadwell maintains a modest, steady equilibrium, where the proximity to the natural landmarks provides both a boundary and a sanctuary for those who call the place home.

Detailed location data for Treadwell includes the postal code (K4K), 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 Treadwell 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.
