The Lowdown on Bubblers: Safety, Law, and Best Practices

With winter approaching, protecting your waterfront property is a top priority. If you’re using or contemplating installing a bubbler system to prevent ice damage, it’s crucial to understand the legal, safety, and operational considerations involved. 

What Is a Bubbler? 

Bubblers are de-icing systems that create zones of agitated and warmer water to prevent ice from forming around waterfront structures. Properly managed, they can protect docks, seawalls, and other infrastructure from the ravages of winter. However, without careful planning, bubblers can create extensive open-water areas, posing safety hazards to unsuspecting ice users. 

Legal Implications in Ontario 

In Ontario, there are no specific laws prohibiting the use of bubblers; however, legal responsibilities are outlined under the Criminal Code of Canada (Section 263(1)), which mandates property owners to “guard the opening in the ice” to prevent accidents. This means owners must adequately warn and mark any open water areas created by bubblers to prevent injuries or fatalities. 

Accident statistics highlight the seriousness of this issue. In fact, the Ontario Office of the Chief Coroner reported that ice-related deaths have averaged approximately 30 fatalities per year over the last five years, with a significant portion occurring in residential areas where open-water zones were improperly marked or unexpected. 

Failure to implement proper safety measures can lead to serious legal consequences, including charges of criminal negligence resulting in manslaughter.  


Risk Management and Safety Tips
 

Given the potential legal consequences of improperly managed bubbler systems, it’s essential to prioritize risk management and take proactive steps to ensure safety. Here are some key considerations to minimize risks for all lake users:

  • Localize your impact: Place and angle your devices carefully to keep the open-water area as small as possible. 
  • Coordinate with neighbors: Avoid overlapping bubbler zones that create hazard zones. 
  • Use controls: Install thermostats or timers to prevent oversized open-water areas from forming. 
  • Mark hazards clearly: Place visible “Danger Open Water” signs and ensure they are accessible from all angles. 
  • Add lighting: Use amber hazard lights at night to mark the open water—avoid red lights, which can resemble snowmobile brake lights and attract risk. 
  • Monitor regularly: If you are unable to be present, arrange for someone to check the area periodically to ensure proper operation and signage. 
  • Consult professionals: Employ experienced contractors for system installation and setup. 


Understanding the risks, legal obligations, and safety measures can ensure your property remains protected while safeguarding others. Exercise good judgment and take proactive steps to prevent tragic accidents this winter.
