This interactive map shows the street layout and satellite imagery for Cotnam Island, 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).
Drag the map to pan to any area of Ontario or beyond. Switch to Satellite view to see high-resolution aerial photography of Cotnam Island and surrounding areas, including streets, buildings, parks and waterways.
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 Cotnam Island.
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.

Cotnam Island is a locality in Renfrew, Ontario, Canada. It is classified as a village / hamlet. Cotnam Island is located at 45.7989°N, 77.0319°W.
Cotnam Island sits low and persistent against the sprawling expanse of Lower Allumette Lake, a sliver of earth defined by the patient weight of the nearby Meath Hill. It lies 6.6 km east-south-east of Pembroke, ON (from Pembroke, ON: bearing 111°T), and is situated 15.6 km west-north-west of Beachburg. The land here holds the silence of the Canadian Shield, where the light at dusk bruises the water into a deep, bruised violet, catching the reeds in a sharp, metallic glint. To the west, the horizon feels pulled toward the presence of Westmeath Provincial Park, while the air carries a crisp, thin clarity that suggests the proximity of the Indian River, winding its way through the quiet brush some 7 km away. The ground itself is stubborn and thick, clinging to the water’s edge with a tenacity that makes the island appear as if it might drift away, yet it remains anchored, a singular point of resistance in the slow, glacial movement of the surrounding basin. The history of Cotnam Island lingers in the seasonal shifts of the local economy, where the land and the water dictate the pulse of human activity far more than any clock. While the thunderous energy of the Chutes de la Rivière Noire lies 16 km distant, the island keeps a more muted, industrious pace, rooted in the legacy of those who first read the currents of these waterways. Life here turns on the practicalities of the season, from the maintenance of shoreline access to the quiet observation of the ice as it thickens or breaks. There is a distinct, solitary dignity to the way the days pass, marked by the call of birds and the shifting shadows of the clouds against the slope of the land, providing a sense of permanence that outlasts the brief, flickering hum of modern transit.

Coordinates: 45.798889, -77.031944. 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 Cotnam Island includes the postal code (K8B), 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 Cotnam Island 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.
