COVID-19 Resources & Updates

Clinical Trials Ontario is committed to helping advance COVID-19 research and clinical trials as quickly and effectively as possible by connecting the clinical trials community, sharing relevant information, and getting studies off the ground efficiently. On this page, you will find helpful resources, relevant news items, Health Canada approved COVID-19 studies, and a list of COVID-19 trials using CTO Stream.

CTO can help you move COVID-19 studies forward quickly

Through CTO’s programming, CTO Stream, the Trial Site Network, and QuickSTART, we can help identify collaborators across the province and assist in managing study start-up at each of these centers. Read more about how we can help you move forward, faster here.
