Regulatory response to COVID-19
The COVID-19 pandemic has created an unprecedented demand on Canada's health care system and has led to an urgent need for access to health products.
As part of the government's broad response to the pandemic, Health Canada introduced new innovative and agile regulatory measures. These measures expedite the regulatory review of COVID-19 health products without compromising safety, efficacy and quality standards.
These measures are helping to make health products needed for COVID-19, such as investigational drugs and vaccines, available to Canadians and health care workers.
We are also working with our international partners on a coordinated and well-aligned approach to this global pandemic. This ensures that our policies and regulatory approaches are aligned and that health products are safe, effective and quickly available to Canadians. Collaboration also helps advance the development of diagnostics, treatments and vaccines that will save lives and protect the health and safety of people everywhere.
Regulating drugs and vaccines sold in Canada
Drugs, including vaccines, are regulated under the Food and Drugs Act and Regulations. They must meet the regulatory requirements for safety, efficacy and quality before they can be sold in Canada. Health Canada's regulatory process involves:
- authorizing the use of a product in a clinical trial
- reviewing data and evidence to provide a product market authorization and
- monitoring and assessing the safety and effectiveness of a product once it is on the Canadian market
We have authorized certain products to treat COVID-19 and its symptoms.
On December 9, 2020, we authorized the first vaccine in Canada for the prevention of COVID-19.

You can search the complete list of drugs and vaccines that have been authorized for treating and preventing COVID-19.
Monitoring COVID-19 variants
Genetic variations of viruses such as the one that causes COVID-19 are common. The federal government is closely monitoring the genetic variants of the virus that causes COVID-19. This includes those identified in the U.K. and South Africa as well as any potential future variants.
Health Canada is monitoring the emerging variants closely. We are working with manufacturers and international regulators to assess the impact of the new variants on the effectiveness of approved vaccines and treatments. If an issue is identified, we will work quickly with the manufacturers and public health laboratories to mitigate those risks and inform Canadians.
Potential drugs and vaccines for COVID-19
There are many potential drugs being investigated in Canada and around the world for use against COVID-19. We are closely tracking all potential drugs and vaccines in development.
Potential COVID-19 drugs currently being investigated in Canadian clinical trials include:
- antiviral drugs
- monoclonal antibodies and other drugs that address inflammation
- convalescent plasma collected from patients who have recovered from COVID-19
- medical gases

Clinical trials for drugs and vaccines
Clinical trials are the most appropriate way for Canadians to access experimental drugs or vaccines that could help treat or prevent COVID-19. During a trial, companies or sponsors collect information on the risks and benefits of a drug or vaccine. Participants must give their informed consent in order to participate.
Sponsors must apply to conduct a clinical trial in Canada. On May 3, 2021, the Minister of Health signed a second interim order (IO) for clinical trials for medical devices and drugs related to COVID-19. This new IO replaces the original signed on May 23, 2020, and continues to support the optional pathway to facilitate clinical trials in Canada that investigate and offer patient access to potential COVID-19 drugs and medical devices, while upholding strong patient safety requirements.
In addition to the interim order, Health Canada is working hard to expedite the authorization of trials for COVID-19. Applications are being reviewed faster than usual to speed up access without compromising patient safety. We are also encouraging companies, academic research centres and investigators who have products in development and pre-clinical data to contact us before they apply so we can advise them on the regulatory process.
See Health Canada's complete list of authorized clinical trials for drugs and vaccines for COVID-19. For a broader list all of authorized clinical trials, including those not related to COVID-19, please visit Health Canada's clinical trials database.
Health Canada reviews scientific evidence of a drug or vaccine, including results from clinical trials, to assess the product's safety, efficacy and quality before it can be sold in Canada. To facilitate earlier access to COVID-19 drugs or vaccines, Health Canada is prioritizing the review of these products while ensuring there is adequate evidence of safety, efficacy and quality to merit access to Canadians.
On September 16, 2020, the Minister of Health signed an interim order that introduces a temporary regulatory pathway. This will help expedite the authorization for COVID-19-related drugs and vaccines without compromising patient safety.
As of October 2020, Health Canada began receiving submissions for approval under the drug authorization Interim Order for COVID-19. Health Canada will carefully review all of the data provided. Before any new vaccine or treatment is made available to Canadians, it must be shown to be safe, effective and of high quality.
The interim order is in effect until September 16, 2021. We have introduced transition measures to ensure that COVID-19-related drugs authorized under the IO may continue to be imported and sold in Canada. These measures have been published in the Canada Gazette, Part II.
As of March 18, 2021, the review, authorization and oversight of COVID-19 drugs, including new drugs, can be conducted under the Food and Drug Regulations. Please refer to the Guidance on modified requirements for drugs for use in relation to COVID-19.
See Health Canada's complete list of applications received for COVID-19-related drugs and vaccines and their status. See also the complete list of all drugs and vaccines that have been authorized for treating COVID-19.
Special Access Program
The most appropriate way to access unproven treatments is through clinical trials. However, the Special Access Program (SAP) is also available to health care professionals who are treating seriously ill patients where conventional therapies have failed, are unsuitable or are unavailable.
The SAP authorizes a manufacturer to sell a drug on a case-by-case basis for an individual who requires access to a product that cannot otherwise be sold or distributed in Canada. Recently, the regulations for the program were modernized to better facilitate access to drugs for Canadians, including treatments for COVID-19. These regulatory changes will:
- reduce the administrative burden on health care professionals requesting access to drugs that have been authorized through the SAP and meet certain conditions
- help to reduce delays in getting a drug to a practitioner to treat their patient in a medical emergency
To access products under the SAP, health care professionals must ask Health Canada for permission and companies must agree to provide the product. We will review the evidence on the drug's safety and efficacy for use in a medical emergency. We will consider each request separately.

Addressing drug shortages
We are actively monitoring the impact of the COVID-19 pandemic on the supply of drugs in Canada. This includes identifying areas in Canada's supply chain where supply may be vulnerable and addressing those vulnerabilities before shortages develop.
We have also introduced regulatory measures to address drug shortages.
On March 30, 2020, an interim order (IO) to prevent or ease shortages of drugs, medical devices and foods for a special dietary purpose was introduced. Among other things, this IO allows companies with drug establishment licences to import foreign drugs that meet similar high quality and manufacturing standards as Canadian-approved drugs. See the list of drugs for exceptional importation and sale.
As well, on September 18, 2020, the Minister of Health approved an IO on preventing and alleviating drug shortages in relation to COVID-19. This IO provides more tools to urgently address drug shortages related to COVID-19 by authorizing the Minister of Health to:
- compel anyone (under certain conditions) who sells a drug to provide information about a shortage or potential shortage of that drug related to COVID-19
- impose or amend terms and conditions on certain drug authorizations for preventing or alleviating a drug shortage related to COVID-19
