Ontario Cottage Country Is Meant for Relaxation—But Safety Should Always Come First

For many Ontarians, nothing says summer quite like heading to the cottage. Whether it's a family retreat in Muskoka, a weekend on Lake Huron, a fishing trip in the Kawarthas or a quiet getaway closer to home, Ontario's lakes and cottages are part of our way of life. Whether we own them or rent them, we love them!

Unfortunately, cottage properties also present unique hazards.

Every summer, emergency responders attend serious incidents involving drowning, diving injuries, falls from docks, ATV crashes, boating collisions, campfire burns and accidents involving poorly maintained decks or stairways. Many of these incidents are entirely preventable.

At Deutschmann de Koning Personal Injury Law, we've spent decades helping people whose lives were changed by serious injuries. While accidents can happen anywhere, property owners have legal responsibilities to take reasonable steps to keep visitors safe.

Understanding those responsibilities can help prevent injuries—and may become critically important if an accident occurs.

What Is Ontario's Occupiers' Liability Act?

Many people believe they can't be held responsible if someone is injured on their property.

That's simply not true.

Under Ontario's Occupiers' Liability Act, anyone who owns, occupies or controls a property generally has a legal duty to take reasonable care to ensure visitors are reasonably safe while on the premises.

An "occupier" may include:

• Cottage owners
• Seasonal property owners
• Airbnb or vacation rental hosts
• Property managers
• Anyone responsible for maintaining the property

This doesn't mean property owners must eliminate every possible risk.

However, they are expected to identify foreseeable hazards and take reasonable steps to reduce them.

Waterfront Safety Begins Before Anyone Enters the Water

Water is often the biggest attraction at the cottage.

It's also the greatest source of danger.

• Children should always be actively supervised around water.
• Strong swimmers should never swim alone.
• Everyone should know where life jackets, rescue equipment and emergency phones are located.
• Many drowning incidents occur only a short distance from shore.

Drownings are often silent and happen far more quickly than most people realize.

Every Boat Needs Life Jackets—Every Passenger Should Wear One

Canadian law requires approved life jackets or personal flotation devices (PFDs) for everyone aboard a pleasure craft.

Unfortunately, many victims were wearing no life jacket at all when they entered the water.

Having life jackets stored beneath a seat offers little protection during a sudden collision or unexpected fall overboard.

The safest approach is simple:

Wear your life jacket—don't just carry it.

This is especially important for:

• Children
• Weak swimmers
• Older adults
• Anyone boating after dark
• People fishing from smaller boats
• Paddleboarders
• Canoeists
• Kayakers

Docks Can Become Dangerous

Docks are often where families gather.

They're also where many serious injuries occur.

Common hazards include:

• Slippery algae-covered surfaces
• Loose or damaged boards
• Missing handrails
• Poor lighting
• Rotting structures
• Electrical hazards from improperly installed wiring

Running on docks, diving into unfamiliar water and horseplay dramatically increase the risk of catastrophic injury.

Never Dive Into Unknown Water

One of the most devastating cottage injuries occurs when someone dives into shallow water.

A split second can result in:

• Spinal cord injuries
• Paralysis
• Traumatic brain injuries
• Permanent disability

Even lakes you've visited for years can change.

• Water levels fluctuate.
• Rocks shift.
• Sandbars move.
• Never assume yesterday's safe diving spot is still safe today.
• When in doubt—enter feet first.

Campfires Bring People Together—But They Can Also Cause Serious Burns

Campfires are part of the cottage experience.

They also demand respect.

Parents should ensure children:

• Stay a safe distance away.
• Never throw combustible materials into fires.
• Avoid loose clothing.
• Never play near burning wood.
• Understand that ashes can remain dangerously hot long after flames disappear.

Always extinguish fires completely before leaving them unattended.

ATVs and Off-Road Vehicles Require Responsible Operation

Many cottages have access to trails and recreational vehicles.

Unfortunately, ATV collisions frequently result in serious injuries.

Safe operation includes:

• Wearing approved helmets.
• Following manufacturer recommendations.
• Avoiding excessive speed.
• Never driving while impaired.
• Carrying only the recommended number of passengers.
• Supervising young riders appropriately.

Uneven terrain, unfamiliar trails and overconfidence often contribute to preventable crashes.

Decks, Stairs and Railings Need Regular Inspection

Cottage properties endure harsh Ontario winters.

Snow, moisture and freeze-thaw cycles can weaken structures over time.

Owners should regularly inspect:

• Deck boards.
• Railings.
• Stairs.
• Handrails.
• Walkways.
• Lighting.
• Loose stones.
• Tree roots creating trip hazards.

Routine maintenance can prevent serious falls.

Alcohol and Summer Recreation

Whether it's boating, swimming, ATV riding or simply walking along uneven shoreline, alcohol significantly increases the risk of injury.

Impaired judgment leads people to:

• Swim farther.
• Dive into unsafe water.
• Operate boats.
• Drive recreational vehicles.
• Take unnecessary risks.

Many serious cottage accidents involve alcohol.

The safest choice is moderation—or avoiding alcohol entirely during higher-risk activities.

Don't Forget About Dogs

Many families bring pets to the cottage.

Even well-trained dogs can become protective or anxious in unfamiliar environments.

Owners should:

• Supervise interactions with children.
• Keep vaccinations current.
• Prevent dogs from roaming freely.
• Recognize signs of stress.

Dog bite injuries can cause permanent physical and emotional trauma, particularly in children.

Renting Out Your Cottage? Your Responsibilities Don't End

Short-term vacation rentals have become increasingly popular across Ontario.

Whether renting through Airbnb, VRBO or privately, owners continue to have legal responsibilities.

Guests should expect reasonably safe premises.

That includes:

• Secure docks.
• Secure railings
• Functional smoke alarms.
• Safe electrical systems.
• Stable decks and stairs.
• Clear walkways.
• Proper maintenance.

Failing to address known hazards could expose owners to liability if someone is injured.

What Should You Do After a Cottage Injury?

If a serious accident occurs:

1. Call 911 if emergency medical assistance is required.
2. Seek immediate medical attention.
3. Report the incident to the property owner.
4. Photograph the area where the injury occurred.
5. Obtain witness information.
6. Preserve damaged equipment if relevant.
7. Keep medical records and receipts.
8. Contact an experienced Ontario personal injury lawyer before discussing settlements.

Early investigation often preserves evidence that may later disappear.

When Does a Cottage Accident Become a Legal Matter?

Not every injury results from negligence.

However, legal responsibility may exist when injuries result from:

• Unsafe docks.
• Poor property maintenance.
• Defective stairs or railings.
• Inadequate lighting.
• Dangerous electrical systems.
• Failure to repair known hazards.
• Negligent supervision.
• Unsafe recreational equipment.
• Boating negligence.
• Dog attacks.

Each case depends on its unique circumstances.

An experienced personal injury lawyer can determine whether another party may be legally responsible.
