Standing offers

A standing offer is an offer from a potential supplier that allows Canada to purchase goods and/or services, at pre-arranged prices, under set terms and conditions, when and if required. It is not a contract until the government issues a “call-up” against the standing offer.

Supply arrangements

A supply arrangement allows departments and agencies to award contracts and solicit bids from a pool of pre-qualified suppliers for specific requirements. Many supply arrangements include ceiling prices that allow departments to negotiate the price downward, based on the requirement.
