Health Canada Clinical Trial Applications (CTAs)

A Health Canada Clinical Trial Application (also called a CTA, but not to be confused with the Clinical Trial Agreement!) is required when Sponsors (individual, corporate body, institution or organization that conducts a clinical trial)are conducting clinical trials from Phases I-III of drug development. This includes trials involving marketed products where the proposed use of the product is outside the parameters of the approved Notice of Compliance (NOC) or Drug Identification Number (DIN), or one or more of the following is different:

  1. Indication(s) and clinical use;
  2. Target patient population(s);
  3. Route(s) of administration, or;
  4. Dosage regimen(s).

The CTA must be filed before the trial is to start in Canada. The Health Products and Food Branch of Health Canada must review the application and notify the Sponsor within 30 days if the application is found to be deficient, or else the Sponsor may proceed with the trial.

This includes Institutional/Investigator-initiated CTAs. There are some modifications, as outlined in the Guidance for Clinical Trial Sponsors document.  

Questions from staff concerning preparation of a CTA may be addressed to Gita Sobhi, HHS Research Pharmacist, 905.521.2100 x 73447/76019 or

Review and Signature by the appropriate institutional authority is required before submitting a CTA to Health Canada. The administrative contacts to facilitate this process are:
