Ontario has black bears. Not grizzlies, not polar bears -- black bears. This matters because most bear safety advice on the internet is written for grizzly country (the Rockies, Alaska), and some of that advice is wrong or counterproductive for black bears. The two species have different behaviours, different threat profiles, and demand different responses. If you're paddling or hiking in Ontario, you need to understand Ontario's bears specifically.
Black Bear Basics
Ontario's black bear population is estimated at 85,000-105,000 animals, concentrated in the boreal and Shield regions where the backcountry camping happens. You are in bear country on virtually every backcountry trip in Ontario. Most of the time, the bears avoid you more effectively than you avoid them.
Black bears are primarily motivated by food. Almost every problem encounter between bears and campers comes down to food: food left accessible, food odours on clothing or gear, cooking smells that draw a bear to investigate. A bear that has never been fed by humans (directly or through sloppy food storage) is typically wary and easily deterred. A bear that has learned to associate campsites with food -- a "campsite bear" -- is bolder, more persistent, and more dangerous.
Campsite bears are a real problem at popular backcountry sites in Algonquin Park and other heavily used areas. These bears have been rewarded for approaching campsites and are not easily scared off by noise or yelling. The solution is prevention: store food properly and don't create the next generation of campsite bears.
Food Storage: The Bear Barrel Debate
The standard food storage container for Ontario canoe trips is a 60L barrel pack. Here's the uncomfortable truth: standard barrel packs are not bear-proof. Bears can claw and chew through them if sufficiently motivated. They're excellent for keeping food dry and organized, but treating them as bear-proof containers is a mistake that leads to overnight visits from bears who know better.
Option 1: Hang your food. The traditional method. Suspend your barrel or food bag at least 3 metres off the ground, 2 metres from the nearest trunk, using a rope over a high branch. This works when done correctly, but "done correctly" is harder than it sounds -- finding a suitable tree branch at every campsite, getting a rope over it (especially in the dark), and achieving the minimum distances requires practice and sometimes luck. Many Ontario Shield campsites have sparse tree cover with branches that don't meet the height requirements.
Option 2: Bear canister. A Garcia Machine Backpacker's Cache canister is genuinely bear-proof -- the bear cannot open it, period. You can leave it on the ground away from your tent and sleep soundly. The downside: it weighs 1.3 kg empty, costs around $80, and doesn't hold as much as a barrel. For trips in high-bear-activity areas, the peace of mind is worth the weight.
Option 3: Bear-proof cooler or locker. Some established campsites, particularly in national parks, have bear-proof storage lockers. Don't count on these in Ontario's provincial park backcountry.
The practical approach for most Ontario trips: Use a barrel for your food storage container (it's waterproof and practical for canoe travel), hang it at night using a proper PCT hang or similar method, and keep a meticulously clean camp. If you're in an area with known bear activity, carry a canister instead.
Camp Hygiene
This matters more than your storage method. A perfect bear hang won't help if your cooking area reeks of bacon grease and your fleece smells like last night's dinner.
- Cook and eat at least 30 metres from your tent. Ideally, your camp has three zones: sleeping, cooking, and food storage, each separated by 30+ metres in a triangle pattern. On small Shield campsites, do the best you can.
- Don't cook in or near your tent. Ever. Don't eat in your tent. Don't store food in your tent.
- Clean cookware immediately after eating. Strain dishwater and scatter it widely, away from camp and water sources.
- Store all scented items with your food: toothpaste, sunscreen, bug spray, lip balm. Bears investigate any interesting smell.
- Change out of cooking clothes before bed if possible. At minimum, don't sleep in the shirt you fried fish in.
- Pack out all food waste, including grease. Don't burn food waste in the fire -- it smells more, not less, when burning.
Bear Encounters
Seeing a bear at a distance (more than 30 metres): You're fine. Watch it. Enjoy the wildlife sighting. Give it space. Make sure it has an escape route and isn't cornered. It will almost certainly leave on its own.
A bear approaching your campsite: This is a bear that has learned to associate campsites with food. Stand up, make yourself big, speak firmly and loudly. Bang pots together. Do not run. Do not turn your back. If the bear continues approaching, escalate your noise and assertiveness. A black bear that is food-conditioned needs to learn that this campsite isn't worth the hassle. If the bear won't leave despite sustained deterrence, move to your canoe as a last resort and paddle to a different campsite. Report the encounter to park staff.
A surprise encounter on a trail: Stop. Speak calmly so the bear knows you're human. Back away slowly. Do not run -- running triggers a chase instinct. The bear will almost always move off the trail once it identifies you as a human.
A bear that follows you or acts predatory (stalking, circling, approaching without stopping): This is extremely rare but is the most dangerous scenario. A predatory black bear is not bluffing -- it sees you as prey. Fight back with everything you have. Do not play dead (that's grizzly advice and will get you killed with a predatory black bear). Use bear spray, rocks, sticks, paddles, anything. Make as much noise as possible. This scenario is vanishingly unlikely but understanding the appropriate response matters.
Bear Spray
Bear spray (capsaicin-based deterrent) is effective against black bears and is legal to carry for wildlife protection in Ontario. Keep it accessible -- on your belt or in your PFD pocket, not buried in your pack. Make sure it's not expired (check the date before the trip). Know how to use it: safety off, aim slightly downward at the bear's face, spray in a sweeping motion, and be aware of wind direction (spraying into the wind is a bad day for you, not the bear).
Bear bangers (noise-making projectiles) are another option. They're effective for scaring bears at a distance but less useful at close range. Some paddlers carry both.
Seasonal Bear Activity
Bears emerge from dens in April-May and are hungry. Spring bears are actively foraging and may be less cautious than summer bears. Summer bears are generally well-fed (berry season) and less interested in your camp if you keep it clean. Fall bears are eating obsessively to build fat for winter -- a behaviour called hyperphagia -- and can be more persistent about investigating food sources. August through October requires extra-diligent food storage.
Bottom Line
Bear problems in Ontario backcountry are almost always human-caused. A clean camp, properly stored food, and basic awareness of your surroundings prevent the vast majority of negative encounters. The bears aren't out to get you -- they're out to eat, and your job is to make sure they're not eating your food. Do that consistently and you'll share the backcountry with bears for years without a serious incident.
