The Ontario Teachers' Pension Plan recorded a 9.2% net return in the first six months of 2026, driven almost entirely by gains in its international private equity book. AIMCo, which manages roughly $210.7 billion for Alberta public-sector employees as of June 30, 2026, posted similar figures after restructuring its private credit allocation and shifting capital toward toll-road contracts and renewable energy projects in jurisdictions with stable regulatory frameworks.

Those returns translated into solvency ratios, the measure of a fund's ability to meet obligations if it wound up today, that now sit between 110% and 115% for most large defined benefit plans in both provinces. That is the highest aggregate level recorded since OSFI began tracking provincial pension performance under the current methodology.

Why the surplus appeared now

The move from barely funded to comfortably overfunded happened in two stages. Public equities rallied through the first quarter, particularly in the technology and energy sectors where Canadian funds have concentrated exposure. Toll-road contracts indexed to inflation and long-term power purchase agreements locked in before rate hikes in 2025 returned high single digits on average.

The second factor was interest-rate stability. Pension liabilities are discounted using bond yields, and when yields rise, liabilities fall. The Bank of Canada held its policy rate at 2.25% through mid-2026, keeping Canadian government bond yields in a range that reduced the present value of future payouts without crushing the equity portfolios meant to fund them. Funds that had hedged their liability exposure using interest-rate swaps saw those positions pay off as yields stopped climbing.

The allocation shift that made the difference

AIMCo's turnaround is the clearer case study. After 2024's internal governance overhaul, the fund reduced its weighting in Canadian commercial real estate, which continues to face vacancy pressure in downtown Calgary and Edmonton office towers, and moved capital into regulated utilities and renewable energy projects in the U.S. and Europe. By the end of Q2 2026, toll-road contracts, airport concessions, and power purchase agreements represented 14% of AIMCo's portfolio, up from 9% two years prior.

Ontario funds, particularly OTPP and OMERS, have maintained higher weightings in toll roads and airport concessions for longer, treating these assets as the fixed-income backbone the bond market no longer reliably provides. When traditional bonds yield 3.5% and a 30-year highway lease delivers 6%, the math is straightforward.

What the surplus creates

Surplus always splits two ways. Employers see an opportunity to pause contributions and redirect cash to operations. Retirees see an opportunity to raise cost-of-living adjustments that have lagged inflation for three years. Both groups have legitimate claims, and the governance structures of most Canadian defined benefit plans give both a vote.

Several Ontario plans are already consulting on COLA increases for 2027, with proposals ranging from 1.8% to 2.5% depending on the fund's long-term liability projections. Alberta's public-sector unions have asked AIMCo's board to consider accelerating inflation indexation for members who retired before 2020, when inflation was still below 2% and COLA provisions were minimal.

The risk is that both sides win. Contribution holidays reduce the cash buffer available if markets reverse in the second half of the year. Higher payouts lock in obligations that cannot be undone if private equity valuations compress or if the commercial real estate drag worsens. A 115% solvency ratio in June does not guarantee 115% in December, particularly when a significant portion of that figure reflects unrealized gains in illiquid assets.

Funds are solvent today because equities performed and rates cooperated. Neither is a law of nature.
