Determining what triggers a mandatory review under the Investment Canada Act (ICA) depends on whether a non-Canadian investor is establishing a new domestic business or acquiring control of an existing Canadian enterprise. Administered by Innovation, Science and Economic Development Canada (ISED) and the Department of Canadian Heritage, the ICA mandates two primary types of statutory filings: "net benefit" economic reviews and national security reviews. Every acquisition of control over a Canadian business by a foreign entity (and every establishment of a new Canadian business) triggers a mandatory ICA filing. Whether that filing requires a pre-closing "net benefit" approval or simply a post-closing administrative notification is determined by specific financial thresholds, investor classifications, and target sector rules.

Analyzing Mandatory Review Triggers Under the Investment Canada Act

Acquisition of Control and Financial Net Benefit Review Thresholds

A mandatory pre-closing net benefit review is triggered when a non-Canadian acquires control of a Canadian business and the transaction value meets or exceeds annually adjusted financial thresholds. Acquisition of control generally occurs upon acquiring a majority of voting shares or all/substantially all operational assets. Financial thresholds vary significantly based on the investor's country of origin and state ownership status:

  • Trade Agreement Private Investors: Higher enterprise value thresholds apply to private investors from countries with free trade agreements with Canada (such as CUSMA, CETA, or CPTPP).
  • WTO Private Investors: Private investors from World Trade Organization (WTO) member countries are subject to a statutory enterprise value threshold.
  • State-Owned Enterprises (SOEs): Acquisitions by foreign government-owned or state-influenced enterprises face much lower thresholds calculated on the book value of assets.
  • Cultural Businesses and Non-WTO Investors: Direct acquisitions of Canadian cultural businesses (such as publishing, broadcasting, film, or music) or transactions involving non-WTO investors trigger pre-closing reviews at a low book value asset threshold.

Mandatory National Security Reviews and Critical Sectors

Separate from financial net benefit reviews, the Canadian government possesses broad statutory authority to review, condition, or prohibit any foreign investment (regardless of deal size, percentage of equity acquired, or investor origin) if the investment could be injurious to national security. Under updated ICA legislative provisions and national security guidelines, national security reviews can be triggered by minority equity investments, joint ventures, or asset acquisitions. Mandatory heightened scrutiny automatically applies to transactions involving:

  • Critical minerals and supply chains (such as lithium, nickel, cobalt, and rare earth elements).
  • Sensitive technologies, artificial intelligence, quantum computing, biotechnology, and defense systems.
  • Personal data-intensive businesses holding sensitive personal information of Canadian citizens.
  • State-Owned Enterprises (SOEs) or foreign investors subject to state influence from non-aligned jurisdictions.

Administrative Notifications vs. Pre-Closing Approvals

Transactions that do not meet the financial thresholds for a mandatory pre-closing net benefit review still trigger a statutory obligation. Non-Canadian investors who establish a new business or acquire control below the review thresholds must file an administrative Notification under the ICA. Notifications can generally be submitted up to 30 days after closing, provided the transaction does not involve cultural assets or raise national security concerns. However, executing a deal subject to a mandatory pre-closing net benefit review or a national security order without prior regulatory approval constitutes an illegal closing, exposing investors to statutory court injunctions, daily financial penalties, and mandatory divestiture orders.

Structuring Cross-Border M&A, Regulatory Timelines, and Their Severe Limitations

Navigating ICA compliance requires foreign buyers and Canadian sellers to incorporate mandatory regulatory approval conditions into cross-border purchase agreements. Parties must account for formal review timelines: net benefit reviews typically require an initial 75-day statutory approval period, while national security reviews can extend transaction closing timelines by several months. Investors must be prepared to submit formal undertakings—such as commitments regarding Canadian management participation, capital expenditure, employment levels, and data localization—to secure net benefit approval from the Minister.

However, corporate leadership and cross-border dealmakers must recognize the severe limitations of legal contracts and closing conditions in insulating a transaction from regulatory intervention under the ICA. Purchase agreement representations, closing conditions, and reverse break-fee clauses cannot compel Cabinet approval or override a federal national security prohibition order. Furthermore, the Canadian government holds broad, discretionary authority to reject proposed mitigation measures or require full divestiture if an investment is deemed contrary to national security or net benefit standards. When a foreign acquisition touches sensitive Canadian sectors, critical minerals, or state-influenced capital, contractual agreements structure the commercial deal, but they can never guarantee regulatory clearance or substitute for proactive government relations and early regulatory engagement.
