Sanctions screening vs. PEP screening: what is the difference?
Sanctions screening checks whether a customer appears on a list a government or body has ordered you not to do business with, a strict prohibition. PEP screening checks whether a customer holds, or is closely connected to, a prominent public position, which is not a prohibition but a trigger for enhanced due diligence. Both are mandatory for Canadian reporting entities, both run through the same AML screening workflow, and both produce false positives for different reasons. This guide breaks down what each actually checks, where they overlap, and how they are handled together in practice.
Sanctions screening and PEP screening are both mandatory checks for Canadian reporting entities, but they answer different questions. Sanctions screening asks: is this person or entity someone the law prohibits you from dealing with? PEP screening asks: does this person hold, or have a close relationship to someone who holds, a position of public trust that raises their corruption or bribery risk? Confusing the two leads to the wrong response when a match surfaces, since one calls for refusal and the other calls for closer scrutiny.
What sanctions screening checks
Sanctions screening matches a customer or transaction against lists issued under Canadian and international sanctions regimes, including the lists that flow from ministerial directives under the PCMLTFA. A confirmed match is strict-liability territory: the regulated entity is legally barred from proceeding, and the obligation is to screen, detect, and act, not to weigh the match against other factors. Because the consequence of a missed match is severe, sanctions screening tends to run with tighter, more conservative thresholds than PEP screening, which produces its own share of false positives from common names and transliteration variants.
What PEP screening checks
PEP screening identifies politically exposed persons, heads of international organisations, and their family members and close associates, at onboarding and through ongoing list refreshes. Unlike a sanctions hit, a PEP match does not prohibit the relationship. It triggers enhanced due diligence: senior management approval, a source-of-funds inquiry, and more frequent ongoing monitoring. PEP status is also inherently tiered, since a former minor municipal official and a sitting head of state both qualify as PEPs but carry very different risk, and a well-built program reflects that tiering rather than treating every PEP hit identically.
Where they overlap and where they diverge
| Dimension | Sanctions screening | PEP screening |
|---|---|---|
| What a match means | Prohibited relationship, in most cases | Elevated risk requiring enhanced measures |
| Response to a confirmed hit | Refuse or exit the relationship, and report as required | Apply enhanced due diligence and closer monitoring |
| Legal basis in Canada | Sanctions regimes and ministerial directives under the PCMLTFA | PCMLTFA enhanced due diligence requirements |
| Ongoing requirement | Continuous re-screening against refreshed lists | Continuous re-screening plus periodic re-assessment of risk tier |
| Common false-positive driver | Transliteration variants of listed names | Homonyms, since PEP registers recur common names more often |
Why most programs treat them as one workflow
In practice, sanctions and PEP screening, along with adverse-media screening, run through the same technical process: real-time matching at onboarding, continuous re-screening afterward, and a disposition recorded on every alert. What differs is the response logic layered on top, refusal for a confirmed sanctions hit, enhanced due diligence for a confirmed PEP hit, so a well-designed screening program routes the two differently downstream even while running them through shared matching and entity-resolution logic. Adverse media typically sits alongside both, since a negative-news finding can affect either a sanctions investigation or a PEP risk rating.
How BriteBase handles both together
BriteBase screens every customer against sanctions, PEP, and adverse-media lists through one entity-resolution engine, so the near-duplicate matches that plague PEP screening in particular are cleared with the same logic that resolves sanctions homonyms. Each hit still carries the specific rationale and response its type demands: a sanctions match routes to refusal and reporting, a PEP match routes to enhanced due diligence, and both produce the recorded disposition a FINTRAC examiner would expect to see. The full detail on how each list is handled is on the screening software page, terms are defined in the AML and KYC glossary, and the product sits on the AML screening solution page.
FAQ
Is a PEP hit the same as a sanctions hit?
No. A sanctions hit means you are legally prohibited from proceeding with the relationship. A PEP hit does not bar the relationship, it triggers enhanced due diligence, including senior approval, a source-of-funds inquiry, and closer ongoing monitoring.
Are Canadian reporting entities required to run both?
Yes. Sanctions screening and PEP screening are both mandatory components of a Canadian AML compliance program under the PCMLTFA, and adverse-media screening is increasingly expected as part of a risk-based program alongside them.
Why does PEP screening generate more false positives than sanctions screening?
PEP registers recur common names more often than sanctions lists do, since political and public-sector roles exist in far greater numbers than sanctioned individuals or entities, so a common name is statistically more likely to collide with a PEP entry than a sanctions listing.
Do sanctions and PEP status need to be re-checked after onboarding?
Yes. Both lists change after onboarding, so both require continuous re-screening. A PEP relationship also needs its risk tier periodically reassessed, since a person's public role and the associated risk can change over time even without a new list match.
Can sanctions and PEP screening run through the same tool?
Yes, and most programs run them together, along with adverse-media screening, through one matching and entity-resolution process. What differs is the response applied downstream once a hit is confirmed, not the underlying screening technology.
