A call provision added to fixed income securities that allows for early redemption by the issuer if certain conditions are favorable.
Investopedia Commentary
Also known as Canada calls, these provisions are typically found on corporate debt issues made by Canadian corporations. With a doomsday call provision, issuers are able to redeem at either par value upon maturity of the fixed income security or at a predetermined rate which is usually a benchmark +/- basis points.
