Rely on a professional malpractice attorney to make sense of your claim.
When you secure the services of a credentialed professional, you place an immense amount of trust in their specialized training, safety protocols, and industry standards. Whether you are undergoing a complex medical procedure or hiring an expert to complete structural work on your property, you rely heavily on their professional competence and duty of care.
You may have hired a professional to design your home, do your plumbing, plan your estate, or safety your vehicle. You may have required surgery or care from a medical provider. Whenever you use the services of a professional, you rely upon the professional practice of this person. If that person’s actions fall below the accepted standard of care and result in injury, financial harm, or property damage, they may be held legally liable to you for all related damages flowing from that failure.
At Fosters Law LLP, we have the experience and network of experts to give you the peace of mind in knowing whether the job was done right and whether the person responsible is in fact accountable.
What Constitutes Professional Malpractice in Ontario?
Professional malpractice – often referred to legally as professional negligence, occurs when a licensed expert fails to perform their duties in accordance with the standard of care expected of a reasonably competent peer in their field.
To establish a successful liability claim, your legal team must prove that a professional relationship existed, that the provider breached their professional standard of care, and that this breach directly caused your physical, emotional, or financial damages.
We represent clients across a broad range of professional liability claims, including:
- Medical Malpractice: Surgical errors, delayed or incorrect diagnoses, failure to obtain informed consent, or medication administration errors by doctors, nurses, dentists, or chiropractors.
- Architectural & Engineering Failures: Faulty structural blueprints, inadequate site supervision, or design errors that result in structurally compromised buildings or unsafe living conditions.
- Contractor & Trade Negligence: Substandard electrical, plumbing, or mechanical work that creates immediate safety hazards, water damage, or electrical fires.
- Estate Planning & Financial Malpractice: Negligent draftsmanship of wills, trusts, or estate plans by legal or financial advisors that leads to major asset loss or costly tax litigation.
- Automotive & Safety Certification Negligence: Mechanics or inspection stations certifying a vehicle as “safe” or roadworthy when severe, underlying safety hazards exist, leading to subsequent accidents.
The Role of the “Standard of Care”
In any professional negligence dispute, the central legal question is not simply whether an error occurred, but whether the professional’s performance fell below the accepted standard of care.
The law does not expect professionals to be absolutely perfect in every scenario. However, it does require them to exercise the same level of skill, knowledge, and caution that a typical, prudent professional in that same field would demonstrate under similar circumstances.
Proving that a professional fell below this standard is incredibly technical. It requires extensive legal analysis, detailed documentation reviews, and authoritative secondary reviews by other accredited specialists.
