Quick Answer
CBSA examines international mail and courier shipments at postal examination facilities across Canada. Officers use X-ray technology, physical examination, and detection tools to identify prohibited goods, undeclared commercial items, and contraband concealed in mail. The volume of international mail entering Canada is enormous — millions of items per year — and risk-based targeting determines which items receive closer examination.
Most people picture CBSA officers at an airport booth or a land border crossing. But a significant stream of CBSA enforcement happens in postal examination facilities — large processing centres where officers screen the millions of international mail items and courier packages that enter Canada every year. This is a distinct and specialized area of CBSA’s operational work.
Why Mail Examination Matters
International mail is a major vector for smuggling. Narcotics, firearms, counterfeit goods, undeclared commercial shipments, and other prohibited items regularly arrive concealed in packages. The growth of international e-commerce — particularly direct shipping from overseas retailers — has dramatically increased the volume of mail requiring customs examination.
CBSA’s postal operations sit at the intersection of customs enforcement and Canada Post’s mail processing network. The relationship requires CBSA to operate within postal facilities while maintaining its independent examination authority.
Where CBSA Postal Examination Occurs
CBSA operates postal examination centres at or adjacent to major mail processing facilities. Key locations include:
- International Mail Processing Centre, Mississauga (Toronto) — The largest international mail gateway in Canada
- International Mail Processing Centre, Vancouver — Pacific region gateway
- International Mail Processing Centre, Montréal — Eastern Canada gateway
- Additional facilities in Ottawa, Calgary, Edmonton, and Halifax
Courier examination also takes place at bonded courier examination warehouses near major airports, where companies like FedEx, DHL, and UPS bring international shipments for CBSA clearance.
What Postal Officers Do
Officers working in mail examination:
Risk-based targeting — Not every package is opened. Officers use advance electronic data (where available), X-ray imaging, and risk profiles to identify packages most likely to contain contraband or undeclared goods. Packages from certain countries of origin, with certain weight and size profiles, or with inconsistent declaration information are flagged for closer examination.
X-ray examination — Industrial X-ray machines provide images of package contents. Officers trained in X-ray interpretation identify suspicious shapes, densities, or concealments. Drugs, weapons, and currency have distinctive imaging profiles.
Physical examination — Flagged packages are opened under CBSA’s authority and the contents examined. Officers document what they find, collect evidence, and take appropriate enforcement action.
Seizure and investigation — Packages containing prohibited goods are seized. Depending on the nature and quantity of the contraband, the matter may be referred to the RCMP for criminal investigation. The intended recipient may be contacted, monitored, or arrested.
Assessment of duties and taxes — Non-contraband packages that are undervalued or misrepresented for customs purposes are assessed for applicable duties and taxes. Penalties may be applied.
Detecting Fentanyl and Other Drugs by Mail
Mail-based drug trafficking — particularly fentanyl and other synthetic opioids arriving from overseas — is a significant enforcement priority. Postal officers receive specific training on:
- Recognizing packaging methods and concealment techniques used to disguise drug shipments
- Safe handling protocols for packages suspected of containing fentanyl (due to the extreme potency hazard even from skin contact)
- Coordination with RCMP and Canada Border Services Agency intelligence for systematic interdiction
Working in Postal Operations vs. Frontline Ports
Postal operations offer a different work environment from airport or land border postings. The work is:
- Less physically demanding than enforcement at a primary inspection booth
- More technically focused — X-ray interpretation, document analysis, chemical detection equipment
- High volume — Processing hundreds of packages per shift rather than individual traveller interactions
- Substantial detection impact — Postal seizures of drugs and contraband are significant components of CBSA’s overall enforcement statistics
Many officers find postal operations deeply satisfying because the detection work is tangible — you are physically finding the contraband rather than inferring it from traveller behaviour.

Frequently Asked Questions
Can CBSA open any international mail package?
Yes. Under the Customs Act, all goods imported into Canada — including mail — are subject to CBSA examination. Canada Post Act provisions govern the process, but CBSA has the authority to open and examine mail for customs purposes.
Do postal examination officers carry firearms?
CBSA postal examination facilities are generally not armed in the same way as frontline ports. The risk profile of the work is different — officers are not directly encountering potentially violent travellers. However, officers remain designated peace officers.
What happens if a drug package is addressed to my home?
If CBSA seizes a package addressed to you containing prohibited goods, you may be contacted by CBSA or RCMP investigators. Controlled deliveries — where investigators deliver the package while monitoring for the recipient — are a common enforcement technique.
How does CBSA handle the volume of international parcels?
Risk-based targeting and advance electronic data allow CBSA to focus examination resources on higher-risk shipments. The vast majority of international mail passes through without examination. The targeting algorithms and intelligence databases are continuously refined.
