A Canadian subsidiary of a US parent discovers, mid-transaction, that a counterparty's account has been frozen under an applicable sanctions programme. Two separate legal regimes now apply simultaneously – one administered by the US Office of Foreign Assets Control (OFAC, the primary US sanctions authority under the Treasury Department) and one administered by Global Affairs Canada (GAC, the Canadian authority responsible for implementing autonomous sanctions under the applicable Canadian framework). The question is not merely whether the account is frozen. The question is what each regime requires next, who must act, by when, and what the consequences of inaction look like across both jurisdictions.
Frozen-account management under OFAC and Canada's autonomous sanctions regime share a common objective – immobilising assets connected to designated persons – but diverge significantly on reporting timelines, licensing architecture, record-keeping obligations, and the extraterritorial reach that each authority claims. OFAC's regime operates through a strict property-blocking model with a short statutory reporting window; Canada's regime imposes disclosure obligations calibrated differently and relies on a distinct licensing pathway. Understanding both simultaneously is the core challenge for cross-border businesses caught between the two. As of May 2026, both regimes remain actively enforced, and the divergences described in this analysis reflect the positions currently in force.
This analysis maps the key divergences across six dimensions: the legal foundation and administering authority; the property-blocking and disclosure mechanics; the licensing routes available under each regime; reporting and record-keeping obligations; enforcement posture and penalty exposure; and the practical steps a cross-border business should take when accounts are frozen under both regimes at once.
Who administers each regime, and what is the legal foundation?
OFAC administers US economic sanctions under authority derived primarily from the International Emergency Economic Powers Act (IEEPA), and in some programmes from the Trading with the Enemy Act (TWEA). Designations produce immediate legal effect upon publication: any property of a designated person in US jurisdiction, or held by a US person, is blocked from the moment of listing. No further judicial order is required. The blocking obligation runs to all US persons, wherever located, and to all transactions processed through the US financial system – regardless of where the parties are domiciled.
Canada's autonomous sanctions regime operates under the Special Economic Measures Act (SEMA) and, for terrorism-related designations, the Criminal Code and the Regulations Implementing the United Nations Resolutions on the Suppression of Terrorism. GAC administers the SEMA-based programmes. The legal mechanism is broadly similar – a designated person's assets are frozen and dealings prohibited – but the authority that triggers the obligation, the scope of persons bound, and the administrative machinery for relief all differ from the OFAC model.
One structural divergence matters immediately: OFAC's extraterritorial reach is broader in practice. A non-US bank processing a US-dollar payment through a US correspondent is fully exposed to OFAC jurisdiction even if it has no US presence. Canada's regime binds persons in Canada and Canadians abroad, but does not assert the same correspondent-banking leverage. For a cross-border business with operations in both jurisdictions, the OFAC thread is therefore the more pervasive compliance risk – though GAC enforcement has intensified in recent years and cannot be treated as a secondary concern.
In our cross-border practice, we regularly advise clients whose first assumption is that a Canadian entity sitting outside direct OFAC jurisdiction can freely manage a frozen account. That assumption is wrong in two directions: first, the US parent's own blocking obligation may run to the subsidiary's actions; second, OFAC's secondary-sanctions risk can reach non-US persons transacting in circumstances that touch the US financial system.
How does the property-blocking mechanism work under each regime?
Under OFAC, blocking is automatic and total. A US person – or any person transacting through the US financial system – who identifies property of a designated person must freeze it immediately and report the blocked property to OFAC within 10 business days of the blocking event. That 10-business-day window is one of the most operationally demanding elements of the regime: internal escalation, legal review, and the OFAC report itself must all occur within it.
The breadth of "property" under OFAC is deliberately wide. It covers accounts, receivables, contractual rights, and in some programmes intellectual property. The 50 percent rule (OFAC's rule treating entities owned 50 percent or more by designated persons as themselves blocked) means that a counterparty's account may be frozen even if the counterparty is not itself on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). Aggregated indirect ownership across multiple designated persons triggers the same result. Screening at the account level is insufficient if ownership screening has not been run to the beneficial-owner layer.
Canada's blocking mechanism under SEMA operates similarly in concept – dealings with a designated person's property are prohibited – but the mechanics of what constitutes "dealing" and the administrative pathway for managing frozen property differ. GAC's guidance clarifies that holding frozen property is not itself a prohibited dealing, but any transfer, conversion, or discharge requires authorisation. The absence of an explicit 10-business-day reporting clock equivalent under SEMA (the obligation to disclose exists but is framed differently) creates a structural divergence that compliance programmes must address explicitly. Practitioners advising on SEMA matters note that the disclosure timeline under the applicable Canadian regulations is framed as a prompt obligation but without the same numerical prescription that OFAC uses.
What does this divergence mean operationally? A US-person financial institution freezing an account must report to OFAC within 10 business days. Its Canadian affiliate, subject to SEMA, must disclose to the Commissioner of the Royal Canadian Mounted Police (or another prescribed authority, depending on the regulation in force) but under a differently worded timeline. Running both disclosure processes in parallel, without conflating their requirements, is where cross-border businesses most frequently create compliance risk.
What licensing routes are available, and how do they compare?
OFAC issues both general licences (standing authorisations permitting a defined category of transactions without a separate application) and specific licences (case-by-case authorisations for an otherwise prohibited transaction). General licences are the first place to look: they cover a range of humanitarian, personal, and wind-down scenarios, and a transaction falling squarely within a general licence requires no application. Specific licences, where general licence coverage is unavailable, require a formal written application. OFAC does not publish processing times as binding commitments; in our experience, timelines vary significantly by programme and by the complexity of the facts presented.
Canada's SEMA-based regime offers a ministerial permit mechanism – a specific authorisation issued by the Minister of Foreign Affairs. The permit is the functional equivalent of an OFAC specific licence, but the procedural pathway, the criteria applied, and the supporting documentation expected reflect GAC's own administrative practice rather than OFAC's. There is no Canadian equivalent of the OFAC general-licence architecture: each Canadian authorisation is case-specific. That asymmetry has a practical consequence: a transaction that a US person can complete under an OFAC general licence without any filing may still require a formal permit application in Canada before the Canadian entity can act.
For businesses holding frozen accounts under both regimes, the licensing risk is cumulative. An OFAC specific licence to release or manage blocked property does not constitute authorisation under SEMA. Equally, a Canadian ministerial permit does not satisfy the US blocking obligation. Cross-border businesses that obtain relief in one jurisdiction and assume it extends to the other create enforcement exposure on both sides.
The position above covers the standard case. Your facts – the counterparty's nationality, the currency of the account, the location of the institution, and the specific programme in play – change the analysis significantly.

How do reporting and record-keeping obligations differ?
OFAC requires an annual report on all blocked property held. This is separate from the initial 10-business-day blocking report. The annual report must be filed each year that property remains blocked, creating a continuing administrative obligation that persists for the duration of the freeze. Record-keeping under OFAC's general framework requires that records be maintained for five years from the date of the transaction – or, for blocked property, for the period of the blocking plus five years. These are specific, enforceable obligations with documentary requirements that enforcement actions scrutinise closely.
Canada's record-keeping obligations under SEMA and the implementing regulations require that records relating to compliance with a prohibition or with a permit be maintained for a prescribed period, but the specific duration and format requirements differ from OFAC's five-year standard. GAC's administrative guidance does not replicate OFAC's annual-reporting requirement for blocked property in the same way. A business that builds its record-keeping programme around OFAC's annual cycle and applies it to Canadian requirements risks both under-compliance on the GAC side (if the Canadian obligation demands more in specific respects) and administrative duplication where the requirements differ.
There is a further divergence in the treatment of voluntary self-disclosure (VSD – the practice of proactively reporting an apparent violation to the regulator before enforcement action commences). OFAC has a well-developed VSD framework in which a timely and complete VSD is treated as a significant mitigating factor in penalty calculations. Canada's enforcement approach under SEMA is less publicly documented in terms of VSD credit, though GAC does consider cooperation as a mitigating factor. Cross-border businesses facing a dual-regime compliance failure should assess VSD timing and content separately for each authority, because the optimal disclosure strategy in one jurisdiction may not translate directly to the other.
What is the enforcement posture and penalty exposure under each regime?
OFAC's civil penalty exposure is significant. The maximum civil penalty per violation under IEEPA-based programmes is the greater of a prescribed statutory dollar ceiling (adjusted periodically for inflation) or twice the value of the transaction at issue. Criminal penalties, available for wilful violations, carry additional exposure. OFAC's published enforcement framework distinguishes egregious from non-egregious cases, and the penalty for an egregious, non-disclosed violation is substantially higher than for a self-disclosed, non-egregious one. Because the penalty basis is per-transaction, a series of payments through a frozen account – each treated as a separate violation – can aggregate to a very large number quickly.
Canada's penalty exposure under SEMA includes criminal prosecution (where knowledge and intent are relevant) and administrative measures. GAC does not publish a comparable civil-enforcement matrix to OFAC's. In our experience, SEMA enforcement actions have historically focused on egregious and deliberate violations rather than on technical administrative failures, but the enforcement environment has tightened and the assumption that a technical breach will be treated leniently is increasingly unsafe.
One enforcement dynamic that cross-border businesses must hold separately is OFAC's approach to non-US persons. OFAC can pursue enforcement against non-US entities when their conduct has a nexus to US jurisdiction – typically through US-dollar clearing, US correspondent relationships, or the involvement of a US person in the transaction. A Canadian entity that causes a US bank to process a payment to a frozen account, even if the Canadian entity is not itself a US person, may generate OFAC exposure for the US correspondent and secondary risk for itself. This extraterritorial enforcement posture has no precise equivalent in GAC's approach under SEMA.
If a transaction has already been flagged – or if a preliminary review suggests a compliance failure may have occurred under either regime – an early analysis of VSD options can preserve choices that narrow as enforcement timelines develop.

Where are the common risk points, and what myths should businesses discard?
The most persistent myth we encounter in cross-border mandates is that a compliance programme built around OFAC standards is "good enough" for Canada. It is not. The two regimes bind different classes of persons, use different disclosure timelines, operate entirely separate licensing pathways, and are enforced by distinct authorities with different published frameworks. A firm that screens only against the SDN List and assumes that SEMA designations will always replicate OFAC listings will miss Canadian-specific designations. The two lists are not identical, and GAC has at times moved on listings independently of OFAC.
A second risk point is the ownership-and-control test. OFAC's 50 percent rule is mechanical: aggregated direct and indirect ownership reaching or exceeding 50 percent by one or more blocked persons produces a blocked entity, regardless of control. Canada's SEMA framework prohibits dealings with property owned or controlled by a designated person, and the concept of control under the applicable Canadian regulations introduces a factual analysis that can capture entities not caught by OFAC's purely arithmetic test. The reverse is also possible: an entity blocked under OFAC's 50 percent rule may not meet the Canadian control threshold in a specific factual scenario. Running both tests on every counterparty is not duplicative; it is required.
A third risk is over-reliance on wind-down periods. OFAC's general licences for certain programmes include authorised wind-down periods that permit specific categories of activity in the period immediately following a new designation or a blocking event. Canada's permit mechanism does not include an equivalent standing wind-down authorisation. A business that relies on an OFAC wind-down general licence to continue operating an account – without separately obtaining Canadian authorisation – will be in breach of SEMA for the Canadian portion of any activity conducted in reliance on that general licence.
In a recent matter, a financial-services group with entities in both jurisdictions identified, through an internal screening review, that a corporate account had been maintained in breach of both OFAC and SEMA obligations for several months following a designation. We assessed the apparent violations under each regime separately, advised on the VSD framework applicable to each authority, prepared the disclosure materials, and managed the queries that followed from both sides. The divergent evidentiary and procedural requirements of the two processes underlined precisely why a single-regime response to a dual-regime failure is structurally inadequate.
What should a cross-border business do when accounts are frozen under both regimes?
The first action is triage: confirm which regime's blocking obligation triggered first, map the overlap, and determine whether any general licence or other standing authorisation covers any portion of the required activity. Under OFAC, the 10-business-day reporting clock starts immediately; that clock governs the pace of everything else in the initial phase.
The second action is a full ownership trace. Both OFAC's 50 percent rule and Canada's ownership-and-control test require a beneficial-owner analysis that goes beyond the first layer of the corporate structure. Incomplete ownership mapping at this stage creates the risk of a subsequent violation if dealings with an entity later confirmed as caught by the applicable test are not immediately frozen.
Third, run the licensing analysis in parallel for each regime. Identify whether an OFAC general licence covers the immediate need. If not, assess the OFAC specific-licence route. Separately, assess whether a SEMA ministerial permit is required for the Canadian entity and, if so, what the applicable criteria and documentation standard is. Do not assume that relief obtained under one regime satisfies the other.
Fourth, assess the VSD position under each regime independently. The OFAC VSD framework is well-established; the Canadian equivalent requires a careful reading of GAC's enforcement posture and the specific programme in play. Timing matters: a late VSD is worth less than a prompt one under both regimes, and the two authorities are unlikely to have aligned timelines for what counts as prompt.
Fifth, design the ongoing record-keeping structure for the frozen-account period. Under OFAC, records must be maintained for the blocking period plus five years. The Canadian obligation must be confirmed against the applicable regulations for the specific programme. An integrated record-keeping protocol that satisfies both is more efficient than two parallel systems built to each authority's minimum standard.
We regularly advise compliance teams and in-house counsel on exactly this sequencing. The mechanics are knowable; the risk lies in treating the two regimes as interchangeable when they are not.

Frequently asked questions on frozen-account management: OFAC and Canada compared
Where do the regimes diverge on frozen-account management?
The most operationally significant divergences are the reporting timeline (OFAC's 10-business-day initial report has no direct Canadian numerical equivalent), the licensing architecture (OFAC operates general licences and specific licences; Canada relies on case-specific ministerial permits only), and the ownership test (OFAC's purely arithmetic 50 percent rule versus Canada's ownership-and-control analysis). The two regimes also differ in their annual reporting requirements for blocked property and in their published VSD frameworks. Neither regime's authorisation satisfies the other's blocking obligation.
Which regime is stricter on frozen-account management?
OFAC is stricter on the pace of initial disclosure – its 10-business-day clock and its annual blocked-property reporting cycle impose defined, enforceable deadlines that Canada's regime does not replicate in precisely the same form. OFAC's civil penalty exposure per transaction is also more transparently documented and, in egregious cases, very large. Canada's SEMA enforcement has historically been less frequent but has intensified; the assumption that it is the lighter-touch regime should not be carried into compliance planning. The correct framing is that each regime is strict on its own terms, and the risks are cumulative for a cross-border business subject to both.
What should a cross-border business do about frozen-account management?
The immediate priority under OFAC is to comply with the 10-business-day reporting requirement while simultaneously running the ownership analysis. For the Canadian obligation, confirm the applicable disclosure timeline under the specific SEMA programme in force. Assess licensing options – OFAC general licence first, then specific licence; Canadian ministerial permit on a parallel track. Evaluate the VSD position under each regime separately. Build record-keeping to satisfy both the OFAC five-year standard and the applicable Canadian requirement. Involve experienced sanctions counsel early: the cost of an unnecessary delay is measured in enforcement exposure and shrinking procedural options.
