Awards & Focus

Areas of Practice
  • Age Discrimination
  • Airplane Collision
  • Automobile Collision

    A motor vehicle collision can leave injured people and their families facing physical pain, emotional stress, and unexpected financial pressure. In many cases, these accidents happen because of careless or negligent driving, and the consequences can include serious or life-altering injuries.

    There are strict deadlines for filing a personal injury claim after a car accident. Waiting too long may affect your ability to pursue compensation for medical expenses, lost income, pain and suffering, and other damages. Speaking with Diamond & Diamond Personal Injury Lawyerscan help you better understand your legal options and the steps involved in the claims process.

    The outcome of a car accident claim can depend on how thoroughly the case is investigated and prepared. An attorney can review the details of the collision, gather evidence, communicate with insurance companies, and work to pursue fair compensation on your behalf.

    Car accidents can result in a wide range of injuries, from whiplash and broken bones to spinal cord injuries and traumatic brain injuries. Getting answers to your questions and learning more about your legal rights from Diamond & Diamond car accident lawyers may help make the process more manageable during a difficult time.

  • Aviation Collision
  • Aviation Liability
  • Aviation Negligence
  • Bad Faith Insurance
  • Brain Injury

    Brain injuries can affect every part of a person’s life, from physical health and cognitive function to employment and personal relationships. At Diamond & Diamond Lawyers, we take the time to understand how a traumatic brain injury has impacted you and your family so we can pursue compensation for medical treatment, rehabilitation, lost income, and ongoing care needs.

    Traumatic brain injuries can result from many types of accidents, including motor vehicle collisions, slip and falls, workplace incidents, and physical assaults. Symptoms may appear immediately or develop over time, and even what seems like a mild headache, dizziness, confusion, or memory difficulty after an accident may point to a more serious condition. A brain injury does not always involve a visible head wound or skull fracture.

    Because the effects of a brain injury can change over time, it is important to seek medical attention as soon as possible and continue monitoring symptoms closely. Family members should also watch for changes in mood, behaviour, speech, balance, or concentration that may indicate a more serious injury. Our lawyers work with injured individuals and their families to help them pursue the financial support needed for treatment, recovery, and long-term care.

  • Catastrophic Injury

    Serious accidents can cause catastrophic injuries that permanently affect a person’s health, independence, and daily life. Injuries involving the brain, spinal cord, severe burns, amputations, or permanent disability often require ongoing medical treatment, rehabilitation, and long-term care. These life-changing injuries can also place emotional and financial pressure on family members who may suddenly need to provide support and assistance.

    Beyond the physical pain, catastrophic injuries may result in lost income, reduced quality of life, and significant future expenses. Individuals and families facing these challenges may have the right to pursue compensation for medical care, rehabilitation costs, lost wages, pain and suffering, and other damages related to the accident.

    At Diamond and Diamond, we represent clients involved in catastrophic personal injury cases throughout Ontario. Our firm understands the impact these injuries can have on every aspect of a person’s life, and we work to help clients pursue fair compensation after a serious accident. Learn more about compensation related to pain and suffering claims involving family members, or contact our team of lawyers to discuss your situation.

  • Child Abuse
  • Civil Litigation
  • Class Action Litigation

    Diamond & Diamond acts for groups of individuals across Canada who have experienced similar harm or losses connected to the same defendant. A class action allows multiple claims to be advanced together, rather than requiring each person to start a separate lawsuit.

    An individual may qualify as a class member if they have been affected in a manner similar to others included in the proceeding. If the Court certifies the class action, it will approve a Class Definition that outlines who is included in the claim and who may be eligible to participate in any recovery or settlement.

    Class actions may arise from defective products, consumer protection issues, data breaches, institutional misconduct, pharmaceutical claims, environmental incidents, and other situations affecting large groups of people. Diamond & Diamond works to pursue claims on behalf of affected individuals and seek accountability from companies, organizations, and other parties alleged to have caused widespread harm.

    Taking the step to explore your legal options after experiencing sexual assault or abuse takes courage. At Diamond & Diamond, we understand that many survivors are looking for more than legal guidance — they are looking for accountability, answers, and a path forward. Our firm is committed to providing a safe, confidential, and supportive environment where your story will be treated with care, respect, and compassion.

    A civil lawsuit can give survivors an opportunity to pursue justice on their own terms, separate from the criminal justice system. In many cases, legal action may help hold both the individual abuser and the institutions that failed to prevent or address the abuse accountable for the harm caused.

    Our legal team is here to support and guide you throughout the process. We approach every case with empathy, discretion, and respect for your privacy. We will explain your options clearly, answer your questions, and work at a pace that feels right for you while keeping your safety and well-being at the forefront.

    Institutions across Canada have a responsibility to protect the people in their care. When schools, religious organizations, employers, foster care agencies, youth programs, rideshare companies, social media platforms, or other organizations fail to take reasonable steps to prevent abuse, they may be held legally accountable. Our firm represents survivors seeking to pursue claims against negligent individuals and institutions.

  • Long-Term Disability

    Living with a long-term disability can affect nearly every part of a person’s life. Along with the physical and emotional challenges that often come with a serious injury or medical condition, many people also face financial uncertainty when they are unable to return to work for an extended period of time. In some cases, a disability may prevent someone from working permanently, making access to long-term disability benefits an important source of financial support.

    Medical expenses, ongoing treatment, and everyday living costs can quickly become difficult to manage without a steady income. When a long-term disability claim is denied or benefits are unexpectedly stopped, the situation can create additional stress for individuals and their families. Understanding the claims process and responding to insurance company decisions can be complicated, especially while managing a serious health condition.

    The team at Diamond & Diamond assists clients with long-term disability matters, including denied claims and benefit terminations. Our firm works to help clients pursue the benefits they may be entitled to and navigate the legal process with clear guidance and support.

  • Malpractice
  • Mass Tort Litigation
  • Medical Liability
  • Medical Malpractice

    When a doctor, nurse, hospital, midwife or other health care provider fails to provide care that meets accepted medical standards, and that failure results in harm, you may have grounds to pursue compensation. Medical malpractice claims can involve serious injuries, delayed diagnoses, surgical errors, medication mistakes, and other forms of negligent medical care.

    Diamond and Diamond assists clients across Canada with medical malpractice matters. These cases often require careful review of medical records, consultation with medical professionals, and a thorough understanding of the legal process. Speaking with a lawyer can help you better understand your legal options and whether you may have a valid claim.
