Corporate Law Update in Canada: Q4 2025

Canada corporate law 2025 entered its final quarter with a notable cluster of regulatory changes, judicial decisions, and compliance updates that affect federally and provincially incorporated businesses alike. Directors, officers, and foreign investors operating in Canada need to understand these shifts to avoid liability and maintain good standing. This guide covers the principal legislative amendments, significant court rulings, updated compliance obligations, and practical implications for businesses of different sizes and structures.

The Canada Business Corporations Act (CBCA) remains the primary federal statute governing incorporated entities, and recent amendments have continued to refine its disclosure and governance requirements. The most consequential change in the current period relates to the beneficial ownership transparency regime. Under amendments to the CBCA that came into force progressively over recent years, private corporations subject to federal jurisdiction are now required to maintain a register of individuals with significant control (ISC register). Enforcement attention has sharpened, and regulators have signalled that failure to maintain an accurate, up-to-date ISC register will attract administrative penalties.

The threshold for "significant control" remains set at direct or indirect ownership or control of 25 percent or more of voting shares or shares carrying 25 percent or more of the fair market value of all issued shares. A common mistake among foreign-owned subsidiaries is treating the ISC register as a one-time filing rather than a living document. In practice, the register must be updated within 15 days of any change in the information it contains, and it must be made available to certain government authorities on request.

Amendments to the Canada Not-for-profit Corporations Act (CNCA) have also introduced clarifications around member meetings conducted by electronic means, reflecting the now-settled practice of hybrid and fully virtual general meetings. Corporations relying on these provisions should ensure their by-laws explicitly authorise electronic participation and that their technology platforms meet the statutory requirements for real-time communication.

At the provincial level, British Columbia';s Business Corporations Act and Ontario';s Business Corporations Act (OBCA) have each seen regulatory guidance updates rather than full legislative amendments in the current period. Ontario';s guidance on unanimous shareholder agreements (USAs) has been refreshed to address situations where a USA purports to restrict or remove director powers entirely, clarifying the liability consequences for shareholders who assume those powers.

The ISC register requirement is the single compliance area generating the most queries from foreign founders and multinational groups. The register must contain the full legal name, date of birth, latest known address, jurisdiction of residence for tax purposes, and the date on which the individual became or ceased to be an individual with significant control. Corporations must take reasonable steps to identify all such individuals, which in practice means sending written requests to registered shareholders and maintaining records of those requests and responses.

A non-obvious requirement is that the obligation extends to indirect control. A foreign parent holding shares through an intermediate holding company must trace the chain of ownership to identify the natural persons who ultimately exercise control. Many groups underestimate the complexity of this analysis when ownership structures involve trusts, partnerships, or nominee arrangements.

Penalties for non-compliance include fines at the corporate level and, in certain circumstances, personal liability for directors and officers who knowingly authorise or permit a contravention. The Competition Bureau and Innovation, Science and Economic Development Canada (ISED) have both indicated that enforcement resources directed at ISC register compliance are increasing.

Practical scenario one: a European private equity fund acquires a majority stake in a Canadian operating company through a Luxembourg holding vehicle. The Canadian subsidiary must identify the natural persons who control the Luxembourg entity and record them in the ISC register, even though those individuals hold no direct interest in the Canadian company. Failure to do so is a contravention regardless of the fund';s good-faith belief that the Luxembourg entity itself is the relevant party.

Practical scenario two: a founder-owned Canadian technology company undergoes a Series B financing round in which a venture capital firm acquires a 30 percent voting stake. The company must update its ISC register within 15 days of closing to reflect the new significant control holder, and must also reassess whether the founder';s percentage has dropped below the 25 percent threshold, potentially removing them from the register.

Canadian courts issued several notable decisions during the current period that clarify the scope of director and officer liability, the business judgment rule, and the duties owed to minority shareholders.

The Supreme Court of Canada';s jurisprudence on the oppression remedy under section 241 of the CBCA continues to evolve. Recent appellate decisions have reinforced that the oppression remedy is available not only to shareholders but also to creditors and other complainants who can demonstrate a reasonable expectation that was unfairly disregarded. Courts have emphasised that the reasonable expectations analysis is contextual and fact-specific, and that a complainant';s course of dealing with the corporation is highly relevant.

On director liability, the Federal Court of Appeal addressed the interaction between the CBCA';s due diligence defence and directors'; obligations under the Income Tax Act in a case involving unpaid source deductions. The court confirmed that a director seeking to rely on the due diligence defence must demonstrate both that they took positive steps to prevent the failure and that those steps were objectively reasonable in the circumstances. Passive reliance on management representations, without independent verification, does not satisfy the standard.

A significant Ontario Superior Court decision addressed the standard of care applicable to independent directors of public companies in the context of a going-private transaction. The court applied the enhanced scrutiny standard where a controlling shareholder stood on both sides of the transaction, requiring the board to demonstrate that the process was fair and that the price was within a reasonable range of fairness. The decision underscores the importance of forming a properly constituted special committee of independent directors and retaining independent financial advisors at an early stage.

Directors of federally incorporated companies should also note recent guidance from the Office of the Superintendent of Financial Institutions (OSFI) regarding climate-related financial risk disclosures for regulated entities. While OSFI';s mandate covers financial institutions rather than all CBCA corporations, the guidance signals the direction of travel for governance expectations across the broader corporate sector.

For public companies and those contemplating a public offering, the intersection of corporate law and securities regulation has produced several important developments. The Canadian Securities Administrators (CSA) have continued to refine their approach to material change reporting, insider trading policies, and the disclosure of environmental, social, and governance (ESG) matters.

The CSA';s ongoing project to introduce mandatory climate-related disclosure requirements for reporting issuers has advanced materially. The proposed rules, modelled in part on international frameworks, would require reporting issuers to disclose governance, strategy, risk management, and metrics and targets related to climate-related risks and opportunities. While the rules have not yet come into full force, boards of directors of public companies should treat the proposed framework as the operative standard for governance purposes and begin aligning their internal processes accordingly.

Insider trading and tipping prohibitions under provincial securities legislation have been the subject of renewed enforcement attention. The Ontario Securities Commission (OSC) has pursued several cases involving the misuse of material non-public information in the context of M&A transactions. A common mistake is the failure to maintain and enforce a formal insider list and a blackout policy that is sufficiently broad to cover all individuals who may come into possession of material non-public information during a transaction process.

For private companies considering a future public offering or a sale to a strategic or financial buyer, the current period';s developments highlight the importance of building disclosure-ready governance structures early. Investors and acquirers conducting due diligence will scrutinise the quality of board minutes, the existence of formal audit and compensation committees, and the robustness of related-party transaction policies.

Corporate law and employment law intersect at the level of corporate governance, particularly for companies with significant workforces in Ontario, British Columbia, and Quebec. Recent amendments to Ontario';s Employment Standards Act, 2000 (ESA) and related regulations have introduced changes to mass termination notice requirements and the treatment of remote workers for the purpose of calculating the threshold that triggers enhanced obligations.

The treatment of remote workers is a practical area where many companies have made errors. Under current Ontario guidance, remote employees whose work is directed from a single Ontario establishment may be counted toward the 50-employee threshold that triggers mass termination obligations, even if those employees are physically located outside Ontario. Companies planning workforce reductions should obtain legal advice before assuming that a geographically dispersed remote workforce reduces their statutory obligations.

At the federal level, the Canada Labour Code amendments addressing pay equity have continued their phased implementation for federally regulated employers. Employers subject to the Pay Equity Act are required to complete their pay equity plans and post them in the workplace. The Pay Equity Commissioner has indicated that enforcement activity will increase, and that employers who have not yet completed their plans are at risk of administrative monetary penalties.

Corporate directors and officers should also be aware that personal liability for certain employment-related obligations - including unpaid wages and vacation pay under the ESA - can attach to directors of Ontario corporations. The due diligence defence available in this context is narrower than many directors appreciate, and passive oversight of payroll functions is unlikely to be sufficient.

What are the consequences of failing to maintain an accurate ISC register under the CBCA?

Failure to maintain an accurate and current register of individuals with significant control is a contravention of the CBCA. The corporation itself may be subject to administrative penalties, and directors and officers who knowingly authorise or permit the contravention may face personal liability. Regulators have signalled increasing enforcement attention in this area. Beyond the direct penalties, an inaccurate ISC register can complicate due diligence in financing rounds and M&A transactions, potentially delaying or jeopardising a deal. Companies should treat the register as a live compliance document rather than a one-time filing exercise.

How long does it typically take to bring a Canadian corporation into full compliance with current beneficial ownership and governance requirements?

The timeline depends heavily on the complexity of the ownership structure and the current state of the corporation';s records. For a straightforward owner-managed company with a simple cap table, a compliance review and register update can typically be completed within a few weeks. For a multinational group with layered ownership structures, the process of tracing beneficial ownership through intermediate entities, obtaining the necessary information from foreign shareholders, and updating all relevant registers and filings can take several months. Professional fees for a comprehensive governance review vary by complexity, but companies should budget at a level commensurate with the size and structure of the group.

Should a foreign company operating in Canada use a federal CBCA corporation or a provincial corporation?

The choice between a federal and provincial corporation depends on the company';s operational footprint, regulatory profile, and long-term plans. A CBCA corporation has the right to carry on business in all provinces and territories under its federal name, subject to extra-provincial registration requirements in each province where it operates. A provincial corporation is generally simpler and less costly to maintain if the business operates primarily in one province. However, the CBCA';s beneficial ownership transparency regime and its director residency requirements - which have been modified in recent years - may make a provincial option more attractive for certain foreign-owned groups. The optimal choice requires analysis of the specific facts, including the industry, the provinces of operation, and the shareholder structure.

The current quarter';s developments in Canadian corporate law reflect a sustained regulatory focus on transparency, director accountability, and governance quality. The ISC register regime, enhanced director liability standards, and advancing ESG disclosure requirements collectively raise the compliance bar for both domestic and foreign-owned businesses. Companies that treat these obligations as administrative formalities rather than substantive governance matters face meaningful legal and reputational risk.
