Occupiers' Liability on Halloween: What Canadian Law Expects of a Walkway on October 31

Strip away the statute numbers and every Canadian province asks the same question. Did the person in control of the property take the care a reasonable person would take, given everything they knew, to keep visitors reasonably safe?

Note the word "reasonably." It appears twice in most versions of the rule, and it matters both times.

One standard, written many times

Ontario's version is typical. Under section 3(1) of the Occupiers' Liability Act, an occupier must take "such care as in all the circumstances of the case is reasonable to see that persons entering on the premises ... are reasonably safe while on the premises." The duty applies whether the danger comes from the condition of the property (a heaved paving stone) or from something you are doing on it (a fog machine pumping across the steps).

"Occupier" is broader than "owner." The statutes cover anyone in physical possession of the property or anyone with responsibility for and control over its condition, the activities on it, or who may enter. There can be more than one occupier at the same time, which becomes important for renters and condo owners later in this guide.

The standard is not perfection. Courts and defence lawyers repeat the same phrases: occupiers are not insurers, they are not expected to remove every possibility of danger, and an ice-free property is not the test. Reasonably safe is the test.

Why October 31 changes the circumstances, not the rule

Nova Scotia's statute is the clearest on what "circumstances" means, because it spells the factors out. Section 4(3) of the Nova Scotia Occupiers' Liability Act tells a court to consider what the occupier knew or ought to have known about the likelihood of people being on the property, how they came to enter, their age, their ability to appreciate a danger, any effort to warn them, and whether the risk is one an occupier could reasonably be expected to guard against.

Read that list with Halloween in mind and it reads almost like a description of the night. You know people are coming. They come by invitation. Many are young. Some are wearing masks that cut peripheral vision and costumes that drag on the ground. It is dark. A loose step you would step over without thinking on a Tuesday afternoon is a different hazard for a six-year-old in a cape at 7 p.m.

The other provinces do not list the factors, but courts weigh the same considerations under the general "all the circumstances" wording. The rule does not change on October 31. The facts the rule is applied to do.

Every province lands in roughly the same practical place, but by three different legal routes. Six provinces have an occupiers' liability statute. New Brunswick abolished the category entirely and uses general negligence. Saskatchewan and Newfoundland and Labrador still rely on the common law. Quebec applies its Civil Code.

The right-hand column barely changes from row to row, and that is the point. Different routes, same destination.

Ontario: the 60-day snow and ice notice

Ontario added one procedural rule that matters if October 31 turns cold. Since January 29, 2021, section 6.1 of the Occupiers' Liability Act bars a lawsuit for injury caused by snow or ice unless written notice, including the date, time and location, is served personally or by registered mail on the occupier or their snow-removal contractor within 60 days.

Two limits are worth knowing. The rule covers snow and ice only, not wet leaves or a dark step. And a judge can excuse late notice where there is a reasonable excuse and the defendant has not been prejudiced, so the 60 days is not an absolute wall. For a homeowner, the practical meaning is simple. A registered letter about a fall is the start of a claim. Send it to your insurer the day it arrives.

Alberta: the province that kept the categories

Alberta is the one province where the trespasser distinction the American articles talk about is still written into the statute. Lawful visitors are owed a "common duty of care." Adult trespassers are owed very little: no liability unless the injury comes from wilful or reckless conduct.

Children are treated differently. Under section 13 of the Alberta Occupiers' Liability Act, if you know or have reason to know a child trespasser is on your property and that something there creates a danger of death or serious bodily harm, you owe that child reasonable care. The test for "reason to know" includes facts from which a reasonable person would infer that the presence of a child "is so probable" that you should act as if one is there. On Halloween night, that is not a hard inference to draw.

Alberta also says a warning, "without more," does not discharge the duty unless it is enough to make a visitor reasonably safe. A "watch your step" sign beside a broken stair is not a repair.

Manitoba and the other statute provinces

Manitoba's 2021 amendment draws a line that maps neatly onto Halloween pranks. Under the current Manitoba Occupiers' Liability Act, a person 12 or older who enters without permission intending to commit a criminal act is owed only a minimal duty: you may not deliberately create a danger to harm them or act with reckless disregard of their presence. Younger children, and anyone who is simply there to trick-or-treat, are owed the full duty.

British Columbia's Occupiers Liability Act similarly deems a trespasser who is committing or intending a criminal act to have accepted all risks. It is also explicit that the duty extends to the "conduct of third parties on the premises," which is worth keeping in mind on a crowded porch.

Prince Edward Island's statute uses wording that mirrors Ontario's, as reproduced in a Miller Thomson case digest quoting section 3.

New Brunswick, Saskatchewan, Newfoundland and Labrador

New Brunswick took the opposite route. Section 2 of its Law Reform Act states plainly that "the law of occupier's liability is abolished," and these cases are decided under ordinary negligence. The question a court asks is functionally the same: was the care reasonable?

Saskatchewan and Newfoundland and Labrador have no occupiers' liability statute, as an adjuster's guide from Dolden Wallace Folick notes, and rely on common-law negligence and common-law occupier rules. These are the only provinces where the older invitee and licensee vocabulary still has real life. Saskatchewan's law reform commission has recommended a statute, but none is in force.

Quebec: the Civil Code's general rule

Quebec has no occupier-specific law. Falls on residential property fall under the general fault rule in article 1457 of the Civil Code: every person must "abide by the rules of conduct incumbent on him, according to the circumstances, usage or law, so as not to cause injury to another." The same article adds that a person can, in certain cases, be bound to repair injury caused "by the act of things in his custody," which is a natural fit for a decoration that falls or a prop that tips.

"According to the circumstances" does the same work in Quebec that "in all the circumstances" does elsewhere.

Halloween runs on an unwritten etiquette that most Canadians learned as children. Light on, come on up. Light off, keep walking. That etiquette turns out to have more official backing than most people realize.

Lights on means come in

Health Canada's Halloween guidance tells households to remove objects around the outside of the house that could cause children to trip, and to "turn on your outdoor lights to increase visibility and let trick-or-treaters know they can visit." It tells parents that children should only visit homes with outside lights on.

So a single switch does two jobs. It is the most effective safety step you can take, and it is a public, government-endorsed signal of invitation. Pumpkins on the steps, decorations on the lawn and an open door all send the same message.

That invitation is also backed by the general law of access. Ontario's Trespass to Property Act creates a presumption that "access for lawful purposes to the door of a building on premises by a means apparently provided and used for the purpose of access is not prohibited." In plain terms, the path to your front door is presumed open for lawful visitors. That is why the walkway, steps and porch are where the duty concentrates. They are the route you have provided.

Lights off means not tonight

The flip side matters just as much. If you are not handing out candy, the clearest thing you can do is turn off the exterior lights, leave the porch undecorated and, if you like, put a simple note on the door. That does not erase your duty to someone who comes up the walk anyway. Alberta's statute is explicit that a warning alone does not discharge the duty, and the other provinces reach the same place through "all the circumstances." What it does is reduce the number of people who come, which is the most reliable way to reduce risk.
