Our journey into contact tracing: The MyTrace/MaTrace project.

Words of thank you to all the community that helped build our project.

A global threat such as a pandemic requires everyone to do their part. As scientists with an applied inclination, we asked ourselves what our research group could do to fight the pandemic. We are indeed engaged in what is perhaps the most natural contribution from our lab, artificial intelligence for drug discovery. The problem with such an effort is that it was not going to be impactful in the short term. We may post in this venue an update on that effort in the coming future.

When we found out about the efforts from MIT’s team on SafePaths, a privacy-preserving mobile app that proposed to use GPS and Bluetooth to assist the process of contact tracing, we saw an opportunity to make a valuable contribution to help Canada come out at the other end of the pandemic curve and reactivate the economy.

We assembled a team of academics, doctors and doctors in training, entrepreneurs, software developers, and other volunteers from a wide range of backgrounds. Together we founded MyTrace/MaTrace, a nonprofit initiative to develop a Canadian mobile app for digital contract tracing. Guided by our research into technologies and approaches, we sought to develop an app that maximized the positive impact on public health while demonstrating the utmost protection of individual privacy and data security.

With the announcement today of a nation-wide contact tracing app, we are closing shop at MyTrace. We are very happy to hear of a nation-wide solution for digital exposure notification and support the widespread adoption of this app. 

We are confident that the app announced today will be a practical, effective tool in the fight against the pandemic, one that does not sacrifice our cherished Canadian values. While the infection curves are flattening, this solution will be crucial as our society reopens and as we work to prevent subsequent waves of the pandemic. 

Our journey with MyTrace was truly inspirational. It epitomized the perseverance, ingenuity, altruism, and dedication of our talented and diverse community in a time of urgency and challenge.

We wish to thank everyone who has participated in and supported us in our endeavour.
