Federal, provincial and territorial roles: legislative and regulatory frameworks
Federal, provincial and territorial levels of government have roles to play in the treatment of substance use disorder and the delivery of a safer supply of controlled substances. In general, the relevant legislative and regulatory frameworks relate to controlled substances and health care service delivery.
Controlled Substances (Drugs)
The Government of Canada administers the Controlled Drugs and Substances Act (CDSA), which establishes a framework for the control of drugs that can result in harm to health or society when:
- misused
- diverted to an illegal market
These drugs are also referred to as “controlled substances.” They include opioids like fentanyl and morphine, and other substances such as methamphetamine.
Under the CDSA, activities with controlled substances are generally prohibited, unless specifically allowed through regulations or by the issuance of an exemption. For example, regulations at the federal level allow for:
- the production and sale of approved prescription drugs containing controlled substances
- the use of such drugs in patient care
Certain other activities with controlled substances are also allowed subject to exemptions from the CDSA. For example, overdose prevention services such as supervised consumption sites must first be authorized through an exemption issued by Health Canada.
All prescription drugs are also subject to the Food and Drugs Act. Before any drug product is authorized for sale in Canada, it must first be reviewed by Health Canada scientists to assess its safety, efficacy and quality.
Health care service delivery
Provincial and territorial governments have most of the responsibility for delivering health and other social services.
Provincial and territorial ministries of health are also responsible for the regulation of health care providers within their respective jurisdictions. In each province and territory, regulatory colleges are responsible for ensuring that regulated health care professionals provide health care services in a safe, professional and ethical manner.
Each province and territory also administers a publicly funded drug plan, which provides coverage to its eligible population based on:
- reimbursed costs
- a unique plan design
- list of approved drugs (formulary)
Formulary lists include thousands of approved drugs (including some that contain controlled substances), and other related health products.
At the federal level, the Government of Canada:
- provides financial support to provinces and territories subject to criteria and conditions set out in the Canada Health Act
- delivers health care services for certain groups of people, such as:
- First Nations people living on reserves
- Inuit
- serving members of the Canadian Armed Forces
- eligible veterans
- inmates in federal penitentiaries
- some groups of refugee claimants
The Non-Insured Health Benefits (NIHB) program is administered by Indigenous Services Canada. It provides eligible First Nations and Inuit clients with coverage for a range of health benefits not covered through:
- other social programs
- private insurance plans
- provincial and territorial health insurance

- dentists
- veterinarians
- nurse practitioners*
- midwives*
- podiatrists*
* subject to federal regulations and the laws and regulations of the province or territory.

Provincial and Territorial: In all provinces and territories medical doctors, dentists and veterinarians can prescribe controlled substances.
For * other health professionals listed, the authorities vary between provinces and territories.
2. Do I have to physically see a practitioner or can they prescribe verbally or electronically?
Federal: You will still need to consult with a practitioner regardless of how the consultation occurs, such as in person or using video.
In addition, during the pandemic, practitioners can issue verbal prescriptions to pharmacists for controlled substances.
Provincial and Territorial: All provincial and territorial regulators have standards and/or policies in place for practitioners who use telemedicine or virtual care.
In addition, provinces and territories have policies in place to ensure the secure transmission of prescriptions while respecting the patients’ right to select their pharmacy.
If a prescription is faxed or electronically sent to a pharmacy, no copy should be provided to the patient to ensure there is no duplication.
3. Who can deliver/transport controlled substances to patients?
Federal: Either through authorities under the Controlled Drugs and Substances Act (CDSA) or through exemptions that were issued, many different health professionals can transport and deliver patient medication. This includes:
- practitioners
- pharmacists
- employees of a hospital
- nurses*
* pursuant to an exemption
In addition, during the COVID-19 pandemic, this has been broadened through an exemption, to include any individual and is not limited to health professionals.
The use of courier services is a common business practice that is also considered acceptable.
Provincial and Territorial: Each jurisdiction or pharmacy may use different methods of delivery and transport. Please contact your local pharmacy for more information.
4. Can a family member or someone else pick up my prescription containing controlled substances for me at the pharmacy?
Federal: Yes, under federal regulations there are provisions that allow you to have someone acting as your agent or mandatary pick up your prescription on your behalf.
Provincial and Territorial: Yes, most provinces and territories have policies and requirements related to having someone pick up a prescription for you. There may be additional measures that are required, such as:
- specifying the person in advance
- showing official identification to be recorded at time of pick up
5. Do patients have to come into the pharmacy to pick up their prescription if it is a drug with controlled substances?
Federal: No, a controlled substance prescription may be delivered to you, or picked up by someone else you designate. Please see questions 3 & 4.
Provincial and Territorial: Please see questions 3 & 4.
6. Can a patient get medications delivered to them?
Federal: Yes. Prescriptions can be delivered to a patient that is self-isolating in their home or elsewhere. Please see questions 3 & 4.
Provincial and Territorial: Yes, there are provincial and territorial policies and guidelines regarding delivery. Care should be taken to ensure that the medication is delivered to the appropriate person.
7. Can I pick up my existing prescription from a different pharmacy?
Federal: Under normal circumstances, you must obtain your medication from the pharmacy that has the prescription on file.
During the pandemic, there is an exception to allow your prescription to be transferred to another pharmacy in the same province or territory*, if this is needed.
* prescriptions with benzodiazepines or other targeted substances such as midazolam or lorazepam can be transferred to another province or territory.
Once a pharmacy has prepared your prescription, you should obtain it from that pharmacy by pick-up or delivery. See questions 3, 4, 5 and 6.
Provincial and Territorial: Please contact your local pharmacy for more information.
8. Are there restrictions on the amount of carries (take home doses) that pharmacists can provide patients?
Federal: The number of carries is not limited under federal regulations.
Provincial and Territorial: There may be provincial or territorial guidelines or policies that practitioners and pharmacists must follow regarding carries.
9. Who can witness opioid agonist treatment (OAT)?
Federal: Witnessing of OAT is not a federal requirement
Provincial and Territorial: There may be provincial/territorial guidelines, policies or scope of practice restrictions about who can witness OAT.
10. How much medication should I obtain at a time?
Federal: Pharmacists will dispense the appropriate amount of medication according to the prescription.
Stockpiling drugs can lead to shortages: Canadians are urged to buy only the amount of medication that they need.
It is important to follow public health guidelines to ensure appropriate access to medications.
Provincial and Territorial: Some provinces and territories have restricted the amount of medication that a pharmacist can dispense during the pandemic to help protect against drug shortages.
Please contact your local pharmacy for more information.
11. Will I be able to switch formulations if my usual formulation is not available?
Federal: The CDSA and its regulations do not contain rules that specifically address this.

- interchanging with a brand name or generic alternative
- using another strength of the drug that is available
- changing the formulation, if available
- determining whether the drug is available at another pharmacy
12. Are there going to be drug shortages in Canada?
Federal: Supply and demand of certain drugs may be affected by the COVID-19 pandemic. Health Canada continues to work closely with industry and provincial and territorial governments to monitor the supply chain to identify and address any components that may be impacted as a result of the COVID-19 pandemic.
On March 30, 2020, the federal government introduced measures to make it easier to import critical drugs, medical devices, and foods for special dietary purposes. These measures will help prevent or alleviate the effects of shortages directly or indirectly related to the COVID-19 pandemic.
Provincial and Territorial: Provincial and territorial governments are:
- collecting information on drug shortages within their jurisdiction
- working with each other, with Health Canada, and with drug supply chain stakeholders to anticipate, mitigate and prevent shortages
Health care providers will look at all options to ensure access to appropriate medication. This may include:
- interchanging with a brand name or generic alternative
- using another strength of the drug that is available
- changing the formulation, if available
- determining whether the drug is available at another pharmacy
- obtaining a verbal prescription, if necessary, to identify an alternate medication with similar effects
