OSFI has finalized the regulatory return changes that federally regulated insurers will use as IFRS 18 comes into force. The September 10, 2026 release gives life insurers, property and casualty insurers and mortgage insurers the final templates they can use to prepare for the new financial reporting standard.
IFRS 18 applies to annual reporting periods beginning on or after January 1, 2027. It changes how financial performance is presented and disclosed, including a new structure for the statement of profit or loss that organizes results into operating, investing and financing categories. Because federally regulated insurers report under international financial reporting standards, those changes flow into the information they submit to OSFI.
OSFI has updated its insurance regulatory returns to keep the supervisory reporting framework aligned with the new accounting presentation. The regulator says the revised templates are being published in advance for planning. Insurers should not switch early. They are expected to continue using the 2026 returns until the first fiscal period to which IFRS 18 applies based on the institution’s own fiscal year end.
That timing matters because not every insurer will cross into the new return set on the same calendar date. An insurer with a December 31 fiscal year end will reach the new framework sooner than one whose reporting cycle ends later. The transition therefore has to be mapped to the institution’s actual reporting calendar rather than treated as a single industry filing date. For insurers, the work is less about a new insurance product rule than about the plumbing of financial and regulatory reporting. Finance, actuarial and regulatory teams will need to make sure the same underlying business is classified and presented consistently across financial statements and supervisory returns. Changes to reporting categories can affect data mapping, controls, reconciliations, internal review and the explanations that accompany unusual movements.
OSFI says the revised returns are intended to support more consistent, comparable and transparent reporting across the insurance sector. That matters to supervision because common reporting structures make it easier to compare institutions and identify changes in risk. The regulator is not asking insurers to restate the economics of their business. It is changing how information is organized and reported as the accounting standard changes.
The practical value of the advance release is preparation time. Insurers can now test their reporting architecture against final templates before the first required filing period. That creates room to identify missing data fields, mapping conflicts and review bottlenecks before they become filing problems.
The change is federal. Provincial reporting obligations and other regulator specific returns remain separate unless the relevant authority adopts corresponding changes. For federally regulated insurers, however, the transition point is now concrete. IFRS 18 begins with annual reporting periods starting in 2027, and the OSFI return package has been adjusted to meet it.
