COVID-19 and CTO Stream

During this period of the COVID-19 pandemic and corresponding state of emergency, CTO remains committed to ensuring that all research personnel and CTO Qualified REBs will have continued access to CTO Stream and all helpdesk related support.

All investigators and research teams should contact their institutions to determine if study activities can continue or if your existing study requires modifications as a result of the potential impact of COVID-19. Before submitting a new study, it is highly recommended that you speak with your institution to ensure this is advisable. At this time certain CTO Qualified REBs have informed us that they are still accepting and reviewing new studies. If your institution approves the submission of a new study, we advise you contact CTO directly before submission.

At this time all CTO Qualified REBs are still accepting and reviewing annual renewals for all active studies. Please ensure you submit the appropriate continuing review forms as per the required deadlines.

If you have any questions please contact CTO at If you have any questions about CTO Stream or require technical support please submit a helpdesk ticket at
