The insurance service result at Canada’s largest private mortgage default insurer has softened across consecutive quarters of 2026, even as overall net income edged higher. That divergence, investment returns improving while the underwriting result weakens, is the signal that matters most to insurance professionals tracking the claims trajectory of the country’s federally regulated default insurance market.
Sagen MI Canada Inc. (TSX: MIC.PR.A) reported Q3 2026 net income of $123 million on November 5, 2026, up $3 million year-on-year. The result was driven primarily by higher investment income and lower operating expenses, partially offset by a weaker insurance service result – the measure of premiums earned against claims and acquisition costs that reflects how the insured book is actually performing – and higher insurance finance expense.
Editor’s note: The press release cites $108 million in its opening line and $123 million in its financial results section. The $123 million figure is consistent with a $3 million year-on-year improvement from Q3 2025’s confirmed result of $119 million, as filed on SEDAR+ (Canada’s securities filing database). Readers should consult the full financial statements on SEDAR+ for a complete breakdown by reporting line.
The directional signal has been building across the year. As covered in our reporting on Sagen’s Q1 and Q2 2026 results, both earlier quarters showed the same pattern – a lower insurance service result and higher insurance finance expense, partially offset by stronger investment income.
The Q3 2026 press release does not disclose loss ratio, claims paid, or delinquency ratio data; those details are in the full Management’s Discussion & Analysis filed on SEDAR+. What can be said from the confirmed record is that the insurance service result, which captures premiums earned against claims and acquisition costs, has weakened across three consecutive quarters while investment returns have supported the headline net income figure.
Mortgage default insurance, the coverage that protects lenders against borrower default on high-ratio mortgages (those with a down payment below 20%), has historically carried loss ratios well below property and casualty lines. What is shifting is the direction, not yet the level.

Canada Mortgage and Housing Corporation’s (CMHC) Fall 2026 Residential Mortgage Industry Report, released October 27, 2026, provides the claims risk context. Ontario’s 90-day-plus mortgage delinquency rate reached 0.32% in the second quarter of 2026 and is forecast to continue rising through mid-2027.
“Canada is not facing a broad mortgage crisis. Financial pressure is becoming more concentrated in specific regions of the country and is appearing first in other debts, before mortgages. The mortgage system is adjusting, but these early warning signs, particularly in parts of Ontario, need to be monitored closely,” said Aled ab Iorwerth, deputy chief economist at CMHC, on October 27, 2026.
CMHC projects Ontario will record the sharpest and most sustained delinquency increase through mid-2027, led by the Greater Toronto and Hamilton Area (GTHA) and Southwestern Ontario, where U.S. tariff exposure and weaker labour market conditions are compounding the pressure. Alberta has continued to improve, while British Columbia is showing moderate upward arrears movement.
For a mortgage default insurer, rising regional delinquencies represent the upstream indicator for claims. When arrears climb in markets that account for a significant share of the insured portfolio, claims provisioning and loss ratio assumptions need to reflect that, which is precisely what the softening insurance service result signals.
The scale of exposure in the insured market has also grown. Federal mortgage rule changes announced by the Department of Finance Canada in September 2024 – effective December 15, 2024 – raised the insured purchase price ceiling from $1 million to $1.5 million and extended 30-year amortizations to all first-time buyers and buyers of new builds. CMHC’s Spring 2026 report noted that insured mortgage activity increased relative to uninsured lending as a direct result of those eligibility changes.
A growing insured book in markets where arrears are rising concentrates more claims exposure inside the default insurance system, in the same geographic regions – Ontario and British Columbia – where delinquency is forecast to remain elevated through mid-2027.
The Office of the Superintendent of Financial Institutions (OSFI), the prudential regulator of federally regulated mortgage insurers including Sagen, confirmed in its January 2026 quarterly release that it is consolidating existing credit risk guidance for mortgage lending into a single, principles-based framework, to replace Guideline B-20. OSFI confirmed that existing debt service expectations will continue applying alongside loan-to-income limits on uninsured mortgage portfolios during the transition.
For mortgage default insurers, the capital framework is provided by the Mortgage Insurer Capital Adequacy Test (MICAT), OSFI’s risk-based framework for assessing whether federally regulated mortgage insurers hold sufficient capital to withstand unexpected losses and financial stress. The regulatory minimum MICAT ratio is 100%, while OSFI has established a supervisory target of 150%.
