Our programs help you conduct more trials, more efficiently

More efficient

Clinical Trials Ontario provides a more streamlined and efficient process to get clinical trials started. Through our flagship program CTO Stream, all participating sites undergo a single ethics review rather than separately applying to local research ethics boards. There is just one application across the province, one consent form.

More centralized

The CTO system enables sponsors to drive and manage a trial at their own pace, providing centralized control and accessibility to trial data.

More cost effective

Through CTO Stream, there are cost savings with five or more Ontario sites. All invoices come through a central body with no contracts required (unless specified). You pay a flat fee through a single invoice, at a very competitive price, and there are no additional fees for continuing reviews or most amendments.


90% per cent of additional sites in CTO Stream gain research ethics approval in less than one month, with nearly half of those gaining approval in less than one week. This means that ethics review for a rescue site can be completed in as little as one month.

Our latest program, QuickSTART, further accelerates start-up times by using automated nudges and notifications to bring sponsoring companies and sites on the same page with respect to budgets and contracts.

Fully supported

CTO’s Industry Concierge Service is helping industry conduct trials in Ontario by providing companies with the contacts and tool they need to get their trial off the ground.
