Department of Finance Canada said the federal government priced $2.5 billion in Canadian-dollar green bonds.
The issuance included $1 billion in a new 30-year green bond and a $1.5 billion reopening of the 7-year green bond issued in February 2025.
Finance Canada said environmentally and socially responsible investors represented 86 per cent of buyers for the new 30-year bond, with a final order book of more than $1.9 billion.
For the reopened 7-year bond, environmentally and socially responsible investors represented 31 per cent of buyers, and the order book exceeded $3.6 billion.
The offerings increased Canada's total green bond issuance since March 2022 to $15.5 billion.
Finance Canada said this was the government's first 30-year green bond offering.
Canada's updated Green Bond Framework, released in November 2023, includes certain nuclear energy expenditures.
Green bonds do not create a tax credit for investors. Their public-finance role is to raise federal borrowing for eligible green expenditures and to provide a sovereign benchmark for Canada's sustainable-finance market.
