The Office of the Superintendent of Financial Institutions is publishing final regulatory return templates for federally regulated insurers, rewriting the forms life, property-and-casualty and mortgage insurers file each year to match a global accounting standard that takes effect for reporting periods beginning in 2027. That standard, IFRS 18, introduces new presentation and disclosure requirements for financial statements, including a new statement of profit or loss structure organized into operating, investing, and financing categories, and OSFI says the redesigned returns support more consistent, comparable, and transparent regulatory reporting across the insurance sector. For finance teams that spend the back half of every year closing out annual filings, the rewrite adds a new line item to an already crowded compliance calendar, even though the underlying business is not changing shape.
A New Three-Way Split for the P&L
The change driving everything else is structural. IFRS 18 introduces three categories for the statement of profit or loss — operating, investing and financing — reshaping how the income statement itself is organized. OSFI has updated its regulatory returns templates for insurers to reflect these categories, providing a preview of the final templates, as detailed in OSFI’s instructions on IFRS 18’s impact on federally regulated insurer reporting. The rewrite is not spread evenly across the paperwork. Most changes affect the core financial return, especially the statement of profit or loss. For preparers, that concentration is arguably the more useful piece of information than the new categories themselves: it tells finance teams which of their many filings deserves the bulk of the retraining and system-mapping work before the switch, and which forms can largely wait.
Two Fiscal Calendars, Two Deadlines
The rewritten forms arrive on two different clocks, tied to each insurer’s own fiscal year-end. For insurers with a December 31 fiscal year-end, the final returns take effect on January 1, 2027. For insurers with an October 31 fiscal year-end, they take effect on November 1, 2027. OSFI’s filing instructions repeat the same split in plainer terms: Filings using the revised OSFI regulatory returns will be expected starting January 1, 2027 (for December fiscal year end filers) and November 1, 2027 (for October fiscal year end filers), as set out in OSFI’s backgrounder on the insurance regulatory returns update. Three specific forms carry the new structure: OSFI has posted updated Life Insurance Return (2027), Property and casualty (P&C) insurance return (2027) and Mortgage Insurance Return (2027) templates. The mortgage insurance update lands not long after OSFI’s recent overhaul of mortgage insurer capital rules, another 2027-dated change for that segment. The staggered effective dates also mean the sequencing matters for groups that hold more than one type of federally regulated insurer under the same roof, since a life and a mortgage insurer sitting inside the same corporate family will not necessarily be moving onto the new forms at the same moment.
What Doesn’t Change: Measurement and OSFI’s Own Analysis
None of this touches how insurers measure what is already on their books. Because IFRS 18 is a presentation and disclosure standard, it does not change how assets or liabilities are measured, and OSFI is explicit that its own supervisory work will not shift either: OSFI supervisory analysis will not change materially because of the changes to IFRS presentation. The rewrite is about where numbers sit on the page, not what they equal. That framing also shaped how OSFI built the new forms in the first place: OSFI developed the final returns based on feedback from industry participants and external auditors, giving preparers a hand in a layout their own audit committees will eventually have to sign off on. For readers trying to gauge how much this actually matters day to day, that distinction is the one worth holding onto: the rewrite is likely to land hardest on financial-reporting and controllership functions, which redraw the forms, rather than on actuarial or capital teams, whose inputs are untouched.
One Template, Judgment Left to Insurers and Their Auditors
Rather than build separate forms for each insurance line, OSFI has designed one standardized regulatory return template, which is similar across the insurance industries. The updated design reflects feedback from select industry participants and external auditors, though OSFI has not named which firms or associations took part. Where the new standard leaves room for interpretation, OSFI is handing that room back to industry rather than filling it in. Institutions retain flexibility to apply their own classification judgments, disclosure requirements, or documentation standards, and on that point OSFI will not be issuing guidance in these areas. Institutions should consult their external auditors to support consistent application of IFRS 18 — pushing the judgment calls that might once have gone to the regulator toward each insurer’s own audit relationship instead. In practice, that likely means two insurers with broadly similar transactions could still end up presenting them differently on the new statement of profit or loss, a common enough outcome whenever a principles-based accounting standard and a redesigned regulatory form land in the same reporting cycle.
A Preview, Not Yet a Filing Requirement
OSFI is careful to frame this as advance notice rather than a new filing obligation. The publication of the updated regulatory return templates provides advance preview for planning purposes. Insurers are not expected to report under the updated templates until the first fiscal period to which IFRS 18 applies based on the institution’s fiscal year end. Nothing changes on the filing side before then: the prior forms remain in use until the insurer’s implementation date. The underlying accounting standard is broader than OSFI’s own forms. IFRS 18 Presentation and Disclosure in Financial Statements is an international financial reporting standard (IFRS) that takes effect in 2027, and more precisely IFRS 18 applies to annual reporting periods beginning on or after January 1, 2027, as set out in OSFI’s guidance on when the new returns take effect — the same horizon OSFI’s own returns are now built around. The release lands in a busier stretch of OSFI insurer rulemaking that has also touched OSFI’s catastrophe bond capital credit rule and OSFI’s credit-risk management guideline for insurers. Taken together, the pattern is one of a regulator that prefers to put paperwork in front of industry well ahead of a hard deadline, then leave the harder judgment calls to insurers and their auditors to work out on their own timeline.
