For Ontario, there is no single universal start date for “hunting season” — it depends on the species and the Wildlife Management Unit (WMU) you’re in, and dates are renewed each year in the provincial hunting regulations.

Quick Scoop

  • Big-game and small-game seasons in Ontario are set by species (deer, moose, black bear, turkey, grouse, waterfowl, etc.) and by WMU, not by one province-wide opening day.
  • In recent years, many fall big‑game firearm seasons for deer in parts of Ontario have opened around mid‑October to early November , while archery for deer in some areas has opened in September.
  • Small‑game species like grouse and hare typically have early fall openings (often around September 1 in many units), giving hunters one of the earliest “starts” to the fall hunting period.
  • Spring black bear and wild turkey seasons usually open in spring (April–May) and are considered the start of the “spring hunting season” rather than the main fall season.

Because these dates change by WMU and sometimes by year , the real answer to “when does hunting season start in Ontario?” is: it starts on different days depending on what you’re hunting and where.

What this usually looks like

To give you a feel, here’s how it roughly lines up in recent Ontario schedules (these are examples, not exact legal dates):

  • Ruffed/spruce grouse & small game
    • Many WMUs: seasons running from around September 1 into winter.
* Practically, this is one of the earliest “openers” for a lot of hunters in the fall.
  • Deer (whitetail)
    • Archery seasons in some units starting mid‑to‑late September.
* Rifle/muzzleloader in many southern and central areas starting **mid‑October through early November** , then running several weeks.
  • Moose
    • Rifle seasons in some northern WMUs starting mid‑September , so in those regions, that’s one of the first big‑game openers.
  • Black bear
    • Spring season often running May–June in many hunt packages (e.g., 2026 bear hunts listed from early or mid‑May to mid‑June).
* Fall bear seasons typically start in **early September**.
  • Wild turkey
    • Spring seasons often in late April through May ; fall turkey seasons may open in October in some areas.

So “opening day” depends entirely on which of these you care about.

Why there’s no single answer

Ontario uses Wildlife Management Units, and each WMU can have its own:

  • Season opening and closing dates for each species
  • Weapon type rules (archery vs. shotgun vs. rifle)
  • Draws and tag requirements for deer, moose, and bear

The official hunting regulations summary is updated annually and lists:

  • Important dates for licence sales and draws
  • Season calendars by species and WMU
  • Bag limits and reporting deadlines (for example, deer report deadlines into January following the season).

Because of this, any one fixed “start” date you hear from friends or forums is almost always only valid for one species in one WMU for one year.

How to find your exact start date

To know when hunting season starts for you , you need three things:

  1. Your WMU number
  2. The species you plan to hunt
  3. The current year’s Ontario hunting regulations

Then:

  • Look up the most recent Ontario Hunting Regulations Summary and the open seasons regulation table; these list dates by species and WMU.
  • If you’re after deer or moose, also check the tentative and controlled hunt dates page for your WMU.
  • For spring bear or turkey, check the current-year spring season tables and any municipal or county notices (some municipalities publish local hunting date reminders).

Simple rule of thumb

  • If you’re thinking “fall hunting season” in southern/central Ontario :
    • Many hunters effectively treat September 1 (small game) or mid‑September (archery deer or moose in some WMUs) as the practical start.
  • If you’re thinking “overall hunting in the year” :
    • The first big, widely‑used openers are usually spring turkey and spring bear in April–May, depending on WMU.

TL;DR: There isn’t one fixed opening day for all of Ontario. Small game often starts around early September, some big‑game seasons begin mid‑September to early November depending on species and WMU, and spring seasons (bear, turkey) open in April–May. Always confirm the current year’s regulations for your exact WMU before heading out, because those are the only dates that count legally.
