This article focusses on a key component of the federal government's debt-management program, Government of Canada marketable bonds. It first provides a broad overview of the characteristics of these bonds and then discusses the workings of the domestic market, from the formulation of a debt-management strategy to the primary issuance of the bonds, the delivery and payment process, and transactions in the secondary market. Recent developments that have enhanced the overall efficiency of the market are also examined. This article is part of a series that describes and analyses features of the Canadian financial sector.
