duty of care laws

TL;DR

  • Duty of care is a key part of negligence law in Ontario and must be proven to recover compensation in a personal injury case.
  • A claim requires four elements: duty of care, breach of that duty, causation, and damages.
  • Duty of care means someone must act as a reasonable and prudent person would in the same situation.
  • You must prove the breach directly caused your injuries or losses.
  • Common liable parties include drivers, doctors, and property owners who fail to act responsibly and cause harm.

 

To recover compensation for your injuries in an Ontario injury case, your case will hinge on the legal concept of negligence. In other words, you must prove that the person that injured you owed you a duty of care and violated it. Only then will you have viable grounds for recovering damages.

General Negligence

Duty of care laws, also known as negligence laws, is the basic underpinning of personal injury lawsuits in Ontario. In order to recover damages, you will need to meet each of the elements of negligence:

  • Duty of Care
  • Breach of Duty
  • Causation
  • Damages

Duty of Care Definition

The legal obligation or duty of care one person maintains to another depends in large part on the fiduciary nature of the relationship between the two parties. Professional relationships, such as between a lawyer and client, or employer and employee, demand heightened diligence. These relationships establish a scope of responsibility that often involves statutory compliance. For example, two motorists owe a significantly different duty to each other compared to a doctor and a patient. The motorist is expected to take basic precautions for safety. The professional must maintain professional competence and supervision, and advise or warn the client or patient.

Generally speaking, however, duty of care laws requires a defendant (or wrongdoer) in an accident or injury case to adhere to a reasonable duty of careful conduct. The plaintiff must prove that the defendant committed a breach of that duty. This negligent breach must be the proximate and direct causation link of the harm or loss suffered by the plaintiff. The court must examine, determine, and evaluate the foreseeability test.

Whether or not a defendant acted reasonably is also subjective. Special duties may be imposed by contractual terms or tortious principles. Ontario courts consider the duty owed to be “the standard of careful conduct that would be expected of an ordinary, reasonable, and prudent person in the same circumstances.” The court will assess risk assessment and preventive measures to determine if the duty was sufficient to prevent the foreseeable injury. If liability is established, the court will compensate the damages and loss. The defendant must mitigate the loss.

Breach and Causation

It is not enough to prove to the court that there was a duty of law of care owed to you by the defendant. You must also show that the duty was breached and that the breach caused your damages. While similar, these theories are not entirely intertwined. A breach of duty of care can be anything from ignoring traffic laws to leaving a spilled drunk unattended on the floor.

Causation requires that the breach of the duty directly led to your injuries. It is not enough for duty to breached if there is no causal link between the breach and the damages you have suffered.

Damages

Finally, damages are a critical element of negligence. Even if someone breaches a duty to you, there is no right to recover if you have not been damaged. For example, it is obviously a breach of a duty to drive safely for another driver to run a red light and strike your car. But if the impact was so insignificant that you were not injured, you could not successfully bring an injury claim. In the end, all four elements must be met for a case to move forward.

Liable Parties Under Ontario Duty of Care Laws

It should come as no surprise that any party could potentially be liable in the right situation. We all owe duty of care to each other in various situations, and sometimes those duties are breached. Some of the most common instances of liability under duty of law of care include:

Drivers – There are a wide range of duties owed to others when you get behind the wheel of a car. Those duties of care extend to other drivers, roadside property owners, your own passengers, and pedestrians. Drivers that fail to follow the rules of the road are frequently liable in personal injury cases.

Doctors – Medical injuries happen every day. When they happen due to the negligent care of a medical professional, monetary recovery may be possible.

Property Owners – May property owners fail to notify their guests of natural hazards or clean up dangerous conditions in a timely manner. In Ontario, these property owners are likely in breach of their duty of care to anyone hurt under these conditions.

If you have any other questions regarding Ontario duty of care laws, an experienced personal injury lawyer can assess your situation and determine if you have a case.

I had a very positive experience working with David, Alex, and their team throughout my settlement process. Alex was professional, responsive, and helpful in guiding me through the preparation and administrative aspects of the case. Communication was smooth, and the process was handled efficiently from start to finish. David’s experience and professionalism were especially evident during the settlement stage. He took the time to explain matters clearly, answered my questions thoroughly, and worked hard to advocate for my interests throughout the process. I am grateful for their assistance and support, and I am very satisfied with the outcome. I would confidently recommend their firm to anyone seeking legal representation.

⭐⭐⭐⭐⭐ — Himelfarb Proszanski (HimPro) I came to HimPro after being wrongfully cut off my Long Term Disability benefits by Sun Life Financial — one of the most stressful and overwhelming experiences of my life. From the moment I signed my retainer, I felt like I actually had people in my corner. David Himelfarb is the real deal. His experience and strategic clarity gave me confidence at every stage. He told me the truth — even when it was hard to hear — and that honesty is what helped me make good decisions, including accepting the mediation outcome. He never oversold anything and he never let me down. Mena Brar was absolutely exceptional. She handled my documentation with professionalism, patience, and precision. I had an enormous amount of paperwork and she kept everything organized and on track. She genuinely cared about the outcome and it showed in every interaction. Selene — incredible communication and follow-through. Always responsive, always on point. She made sure I was never left in the dark. This team went up against a major insurance company and a complicated situation that they made easy they delivered. If you're dealing with a disability claim denial in Ontario, don't wait — call HimPro. I'm grateful to all three of them. — Ellis St. Croix

Dear David, I just wanted to take a moment to say thank you — sincerely, and from the deepest part of my heart. When I came to you, I was worn down. The longest year of fighting a system that seemed designed to make people quit had taken everything out of me. I had the truth on my side, but I didn't know if that would ever be enough. You made it enough! You took my case, you believed in it, and over the course of a year you saw it through to the end with a level of care and skill that I will never forget. It has been a long year — but the right kind of long. The kind where you know the work being done matters. The settlement we reached means I can finally breathe again. I can clear the slate, rebuild, and step into something new and re invent myself — a life I can actually look forward to. That door would not have opened without you, and I want you to know that I understood that every single step of the way. You are genuinely exceptional at what you do. But more than that, you handled everything with integrity, with patience, and with real human decency. In my experience, that combination is rare. I was lucky to have you in my corner!! Thank you so very much, David. From the bottom of my heart — truly. With deep gratitude and respect, Ellis St. Croix

HIMPRO recently represented me for an insurance claim. They are a great firm, and more importantly, genuinely good people. I highly recommend them. From the beginning, they handled my case professionally and compassionately. Mena was amazing, her attention to detail and understanding made the process so much better. David and Silene also worked on my file and they were both honest, and highly knowledgeable lawyers. I felt fully informed and I was able to trust their judgement completely. My case was resolved in a very reasonable time given my circumstances. In my opinion, you will not be able to find a better group of people to handle your legal issues.
