The plan has pledged at least $10 billion in new Canadian investments over the next five years
OMERS earned a 4.8 percent net investment return in the first half of 2026, adding $6.9bn to push net assets to $151.6bn as at June 30.
Public equities drove the result, with all asset classes contributing positively, according to the plan's figures for the period from January 1 to June 30.
"All asset classes contributed positively to our overall result, led by public equities," said Jonathan Simmons, OMERS chief financial and strategy officer.
Currency tailwinds added a net 1.4 percent to returns, he said.
The Ontario pension plan invested $1bn in Canadian equities over the six months and, as per its results, has committed to adding at least $10bn in new domestic investments over the next five years.
Blake Hutcheson, the plan's president and chief executive officer, said the current environment in Canada "has considerable potential," while stressing that OMERS keeps a geographically diversified portfolio to meet its long-term pension obligations.
About half of the plan's holdings remain in the United States and roughly a quarter are domestic, BNN Bloomberg reported.
Over the past decade, OMERS said, it has added more than $78bn to the plan.
The fund runs the defined-benefit plan for 665,000 members, according to OMERS, covering employees of Ontario municipalities, school boards, local boards, transit systems, electrical utilities, emergency services and children's aid societies.
Hutcheson said OMERS will keep assessing opportunities to deploy capital in line with its risk-adjusted return targets through the rest of 2026.
