In 1999, Dr. Chaim Roifman, a global expert on Primary Immunodeficiency,  Mr. Jay Lefton and Mr. John Perl established the Canadian Immunodeficiency Society (CI Society) to provide patient support, education and research into a cure for Primary Immunodeficiency.

In 2006,  Richard Thompson joined as Chief Executive Officer, additional Board members were recruited, programs were expanded and today the CI Society is a leading national organization working with health science centers and hospitals across Canada.

During 2012, the CI Society undertook a branding exercise with donors, patients, volunteers and healthcare professionals to better reflect the goals and expanded programs and services of the organization. The outcome was a new branding image, Immunodeficiency Canada, while maintaining the legal name of Canadian Immunodeficiency Society.

It continues to uphold Imagine Canada’s Ethical Fundraising and Financial Accountability Code. Immunodeficiency Canada (Canadian Immunodeficiency Society)  is a registered charity, # 87276 0897 RR0001.
