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

Chelmsford is a compact rural community in Sudbury, Ontario, Canada. It is classified as a town. Chelmsford is located at 46.5786°N, 81.1969°W.
Chelmsford rests upon the broad, fertile floor of a basin that holds the quiet weight of the northern shield. It lies 9.7 km west of Grand Sudbury, ON (from Grand Sudbury, ON: bearing 271°T), and is situated 9.7 km west of Greater Sudbury. The land here is defined by a low, persistent horizon, shadowed by the presence of Blueberry Hill which rises to catch the long, slanted light of late afternoon. Beyond the immediate fields, the Vermilion River carves a deliberate path through the earth, marking the land roughly 6 km away, while the expanse of Whitewater Lake sits 7 km distant, reflecting the cooling sky. Further afield, the rush of High Falls drops into the stillness 14 km from the centre, and the sheltered woods of Windy Lake Provincial Park offer a sanctuary 20 km out, grounding Chelmsford in a geography of deep, shadowed water and stone. The history of Chelmsford carries the persistent grit of agricultural roots and the industrial pulse of the surrounding region, where the work of generations has shaped the economy of the valley. Life in Chelmsford moves with the steady, predictable turning of the seasons, a cycle felt in the way the air thins and sharpens as winter approaches. The community maintains a distinct identity, one that values the endurance of its people and the quiet resilience required to thrive in this particular northern landscape. Whether through local gatherings or the quiet maintenance of the land, the inhabitants of Chelmsford sustain a connection to their surroundings that is as practical as it is profound, finding beauty in the stark, honest clarity of the northern light.

Detailed location data for Chelmsford includes the postal code (P3N), 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 Chelmsford 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.
