Who We Are

Annette Lefebvre Avocats is in a unique position to serve your needs given our combined medical and legal expertise.
As a former I.C.U. nurse, Annette Lefebvre has dedicated her law practice of over 30 years to exclusively representing patients and their families in medical malpractice and personal injury lawsuits. As part of the team since 2012, Melissa Lonn brings her social work and science experience to advocate for our clients, all of whom are seeking recourses against doctors, nurses, hospitals and property owners.

Our Approach

All of our clients are individuals with unique stories of injuries suffered as a result of negligence. We listen, and we take the time to carefully piece together the puzzle so that we can provide concrete answers of what can be done.

Our team works closely with each client not only to attain financial compensation, but also to ensure that those responsible for the negligence are held accountable so that errors with devastating effects do not reoccur.

Our Approach
Our Expertise

Our Expertise

With our combined medical and legal knowledge, we are able to sift through complex, voluminous medical records with ease and determine whether or not you have a winnable case. Finding the right expert is key to the success of your case.

Over the years, we have assembled a vast team of leading experts in every area of medicine who help us evaluate the issue of fault and the extent of your injury. Other experts such as engineers, architects, occupational therapists and actuaries may be necessary to determine whether premises are faulty, whether you are able to return to work and the amount of money required to compensate your damages (pain, suffering, permanent impairment and financial loss).
This expertise is essential to building a strong and persuasive case. Our team will take care of everything!


At Annette Lefebvre Avocats we do not want your financial situation to be the reason why you decide not to seek legal counsel. That is why we work on a Contingency Fee basis – this means our professional fees are paid as a percentage of the total amount we recover for you in a settlement or at trial. This fee is only billed at the end of your case when we obtain the funds.

Medical Malpractice

Your doctor, hospital and C.L.S.C. have a duty to act with prudence and diligence in delivering health care.

Personal Injury

Property owners have a duty to act with prudence and diligence and ensure their property is safe.

Birth Injury

Birth trauma pertains to injuries sustained by newborns during pregnancy, labor, delivery, or the immediate post-delivery period.

Spinal Cord Injury

A sudden, severe impact to the vertebrae, discs, ligaments, or spinal cord itself is a common cause of spinal cord injury.

Product Liability

Manufacturers have a duty to ensure that consumers are not injured by unsafe or defective products.


The severity of your permanent incapacity will dictate the amount of compensation you can recover.
