Contract dispute resolution (OPO ADR)

When a federal contract in performance goes sideways — a disagreement over what the terms mean or how they apply — either party can ask the Office of the Procurement Ombud (OPO) to help resolve it, at no cost, without going to court. This is dispute resolution for existing contracts, not bid challenges.

What it is

Per the CanadaBuys Supply Manual (section 8.140.1) and OPO's own service pages, the Office provides alternative dispute resolution (ADR) for disputes relating to the interpretation or application of the terms and conditions of a federal contract. Any one party — the supplier or the government organization — can request it, and both parties must agree to participate because the process is voluntary. Services are offered by OPO's trained, certified facilitators and mediators, at no charge to the parties (parties may bear miscellaneous costs like travel if a session runs outside OPO's office). The mandate rests on the Procurement Ombudsman Regulations.

How the process runs

OPO offers two formats: facilitation, an informal process where a neutral certified mediator relays between the parties so each understands the other's views, and mediation, a more formal guided discussion aimed at a mutually acceptable solution. The requester submits a written request with a brief summary of the issues, a copy of the contract, and the names of the parties. OPO then has ten working days to determine whether the request falls within its ADR mandate and invite the other party; the other party has ten working days to respond; if both agree, OPO issues a proposal covering logistics and issues, and runs the session. A settlement produces a legally binding document drafted by OPO. Discussions are without prejudice, participation can end at any time, and if a party declines, the session does not proceed — though OPO may still offer informal facilitation case by case.

What it means for vendors

ADR is the low-friction route when performance disputes stall: no filing fees, a neutral setting, and a process built to preserve the business relationship rather than end it. It doesn't strip your legal options — participation is voluntary and nothing said in the session prejudices later proceedings. But scope matters: OPO ADR covers contract-term disputes, not procurement fairness complaints about how a competition was run (those belong with the contracting authority, the Tribunal, or OPO's separate complaint review). For a bid-side challenge, see the CITT bid challenge process.

Common questions

Who can request OPO ADR?

A party to the contract: a Canadian supplier, an international supplier with a place of business in Canada, or a federal organization listed in Schedules I, I.1 or II of the Financial Administration Act, per the Procurement Ombudsman Regulations.

Is a mediated settlement enforceable?

Yes — if the parties reach agreement, all parties sign a legally binding document drafted by OPO. If they don't, the mediator records progress and next steps, and the parties are free to pursue other remedies.

What if the department refuses to participate?

The ADR session will not take place — the process is voluntary for both sides. OPO informs the parties, answers questions, and may in some cases offer informal facilitation or continue among the parties that accepted.
