In Conversation with Opher Baron: On the Making of an Online Canadian PPE Marketplace

For the second instalment of our 2020–21 speaker series, we had the pleasure of joining Dr. Opher Baron, Professor of Operations Management, from the University of Toronto’s Rotman School of Management. He shared his journey creating a Canadian marketplace for personal protective equipment (PPE) to help bridge the crucial supply chain gaps that swept across the country during the early stages of the COVID-19 pandemic.

Through this interview, we learn how the expectations of traditional PPE supply chains were fundamentally changed by the onset of COVID, shifting from a norm of relatively limited quantities and demand to a sudden, dramatic, and global increase in need. Dr. Baron delves into the way WeChat in Wuhan, China provided insight into effective PPE distribution and the ability of tech platforms to leverage the benefits of open, transparent marketplace dynamics for both large and small scale equipment procurement.

Recognizing the significant need for better access to the Canadian PPE supply chain, Dr. Baron, his colleagues, and volunteers created the COVID PPE Help platform ( The site brings together PPE suppliers and customers, increasing market transparency for both sides and facilitating the efficient distribution of PPE. Thanks to the team's tireless commitment, the platform continues to be a powerful tool used by Canadians in order to adequately provide PPE to front line workers and Canadians from coast to coast.

With a group of volunteers led by Dr. Val Kobylianskii they launched in late April 2020. This free platform effectively connects customers and suppliers of PPE. The platform now helps non-for-profit and charitable organizations to get discounted PPE and operates a group buying offer that allows small customers to purchase PPE at wholesale prices.
