Hotzones in view
Where the animal you picked is most likely to be, based on cover, food, water, mapped deer yards and moose areas, terrain, roads, time of year, harvest history and your own sightings.
Activity forecast
Find hotzones or tap "Use map centre" to see the next 7 days.
Kept on this device. Export GPX now and then as a backup. It opens in Garmin, onX and Gaia too.
Offline areas
For places with no signal. Pick what to save; you'll see roughly how big it is first.
The map on screen (12 to 45 km across) with every layer you have on, at full detail, plus what hotzones, camps and paths need.
Land, roads, closures, cuts, Ontario air photo and hotzone data for the whole unit.
Land and WMU lines, forest roads and Ontario air photo for the whole province. Hotzones need a WMU or on-screen save. More provinces as we add them.
True North Nav Outdoors
Hunt planning for Ontario: where you can hunt, when it's open, where the animals likely are, and how to get there.
Before you head out
This is a planning aid, not the law. Seasons were copied from Ontario's 2026 tables, which Ontario calls tentative. Check the Hunting Regulations Summary.
Hotzones are predictions. They point at likely ground to scout. They don't see animals.
Green isn't a free pass. Crown land can be under lease, licence or mining claim, posted, or behind private land, and townships have firearm bylaws. Yellow covers everything not mapped as Crown land, so assume you need permission there.
Crown land camping: free for Canadian residents, up to 21 days on one site per year. Most non-residents of Canada need a permit north of the French and Mattawa rivers.
How hotzones are worked out
The map is cut into squares about 250 m across. Each square gets points for what the animal you picked wants at that time of year, then the best squares in the area show as hotzones.
- Cover and food: forest, fields and edges, wetlands, lakes and shorelines (Ontario's maps plus OpenStreetMap).
- Young regrowth: cutovers from satellite forest-loss maps (4–20 years old is prime browse) and burns from Ontario's fire records.
- Ontario biologists' maps: deer yards, moose aquatic feeding, rutting and wintering areas, travel corridors, mast stands.
- Pressure and terrain: distance from roads, slope, benches.
- Time of year: moose rut, late-fall browse and so on each weigh things differently.
- Harvest numbers by WMU when that file is loaded.
- Your own history: markers for harvests, spots you've hunted, stands, sign and cameras, plus your sightings, pull hotzones toward them. Add them with Add → Marker, or import old GPS waypoints.
Scores are relative to the area you're looking at. It can't see beaver floods, fresh cuts newer than the satellite map, or where other hunters park, so your own markers matter most.

Ontario Hunting Regulations Summary · Deer and moose season dates
Gets the newest version of the app and its prediction model, the latest season dates and rules file, fresh land, roads, WMU, wildlife-area and habitat data from Ontario, the newest satellite cutover year, and new map squares. Then it re-runs your last hotzones or trip plan on the fresh data. Your saved spots, routes and camps stay. Ontario publishes regulation changes on ontario.ca as web pages, so the season file is updated by hand when they change. Check the links below too.
