Mastocytosis Society Canada (MSC) is a registered Canadian charity.  

MSC was created to assist patients, caregivers and health care professionals learn more about mast cell disorders and to lean on each other for support. The audience we support is quite diverse and includes:

  • newly diagnosed patients,
  • patients in search of a diagnosis,
  • caregivers of young children or elderly parents with mast cell concerns and
  • health care professionals who are trying to provide the best health care they can to their mast cell patients.

Around the world, and in Canada, there seems to be a growing number of patients being diagnosed with mast cell disorders such as Mastocytosis and Mast Cell Activation Syndrome (MCAS). Often times, these patients have never heard of this diagnosis and immediately take to researching it on-line. MSC is here to support these patients by:

  • Helping them understand the facts about mast cell disorders and the triggers and symptoms that many patients experience.
  • Helping them find a health care professional with knowledge and experience with mast cell disorders close to their location.
  • Providing them information on diagnostic testing, medications and other questions to ask their health care professionals.
  • Suggesting ways to help improve their quality of life through diet, eliminating triggers and managing their environment.
  • Creating educational curriculums for patients and health care professionals to help educate and raise awareness of mast cell disorders to speed up diagnosis and improve quality of patient’s lives.

Although MSC is mainly focused on providing support to Canadian residents, we are happy to extend that support to patients around the world who are suffering from this debilitating disease.


To live in a world where those who suffer from rare disease get the help and support they need.


Mastocytosis Society Canada is a global leader in the education and support of those who are managing mast cell disease. We are the first choice of patients, caregivers and health care professionals who are seeking knowledge and advice about Mastocytosis and Mast Cell Activation Syndrome (MCAS). We seek to improve the quality of life for all patients suffering from mast cell disease.


Respect - Every patient, caregiver and health care professional deserves our respect. We respect their opinions, their situations and their privacy.

Compassion - Every person who seeks support from MSC will receive empathy, compassion and understanding for their unique situation. We will help and support them to the very best of our ability.

Competence - We are volunteers and do not provide medical advice. However, we will seek to be as knowledgeable as possible to provide the best support we can.

Teamwork - No one is capable of doing it all, therefore we commit to working together as a team of volunteers to achieve our goals and objectives.

MSC is focused on several key initiatives to help meet our key objectives and provide the best support we can.  

  1. Medical Advisory Committee - MSC recently created a Medical Advisory Committee made up of a team of health care professionals (doctors, nurses, naturopaths, dieticians) who will leverage their knowledge and experience to help create health care protocols and assist in raising awareness of mast cell disease within the medical community.  If you are a medical professional and wish to join this committee, please contact us at
  2. Educational Programming - MSC is focused on creating programming to help educate patients, caregivers and physicians on mast cell disease.  This programming will focus on key aspects of mast cell disease including diagnosis, treatment, nutrition, etc.  This information will be delivered through a variety of mediums including brochures, website, video, web conference, etc.
  3. Canadian Physician List - MSC continues to focus on compiling a list of physicians across Canada who have knowledge and experience with mast cell disease.  If you require assistance finding a physician in your area, please email us at
  4. Fundraising and Volunteering - Achieving these initiatives requires money and volunteer support.  MSC is continually looking for opportunities to raise money through grants and personal donations.  Please contact us if you would like to volunteer your time or make a donation.
