Our Group

The McPeak-Sirois Group for Clinical Research in Breast Cancer is a charitable organization bringing together public health organisations in Quebec. It was launched in 2015 by Susan McPeak, survivor and Charles Sirois, a renowned entrepreneur and caregiver to his wife. In just a few years, the McPeak-Sirois Group has become one of the most important breast cancer clinical research consortiums in Canada.

Our Mission

Our mission is to fight breast cancer more effectively by increasing patients’ access and participation to clinical trials in the various regions of Quebec.

Our Vision

Our vision is to bring together the main players in breast cancer clinical research to make research that cares accessible to as many patients as possible.

Our Co-founders’ Commitment

« In August 2001, I was diagnosed with breast cancer and had a 40% chance to live my next five years. I was fortunate to be offered to participate in a clinical trial that would give me access to state-of-the-art treatment. All these years later, I am very grateful to have had access to this experimental treatment to which I attribute my survival.

My husband Charles supported me throughout this fight, and together we decided to get involved in offering the best care available to the greatest possible number of breast cancer patients in Quebec. Our vision was that the fight against breast cancer would require increasing access and participation in innovative research trials.

This is how, in October 2015, the McPeak-Sirois Group for Clinical Research in Breast Cancer was launched, a private initiative bringing together public institutions, an achievement we are particularly proud of. »
