Bidders' Conferences

A bidders' conference is a meeting held by a procuring organization during a competitive solicitation to explain the requirement and answer prospective suppliers' questions. It takes place after the solicitation is published and before the bid closing date, and it gives suppliers direct access to the buyer's team.

NATO describes it as an event that may be conducted during the solicitation phase, alongside responding to companies' questions about the solicitation. Canadian federal departments use the same term in individual solicitations published on CanadaBuys, where the conference can be optional.

How a bidders' conference fits into a solicitation

The term is used in competitive procurement for complex goods, services, construction, maintenance and defence-related requirements. A conference is tied to a specific solicitation, such as an invitation for bids, an invitation for international bids or a request for proposals.

It is often held together with, or separately from, a site visit. It also sits alongside the formal question-and-answer process. Information given at the conference can be issued to all potential bidders through an amendment, written answers, a presentation, a recording or a procurement notice. NATO defines a bidder as a vendor actively participating in a specific procurement by submitting a formal bid or proposal in response to a solicitation, as set out in its procurement procedure.

How NATO runs bidders' conferences

NATO's procurement process page says that during the solicitation phase NATO answers companies' questions and may also conduct a bidders' conference, depending on the opportunity. NATO's procurement manual treats site visits and bidders' conferences as procurement activities and covers them in its procedures.

A NATO Joint Warfare Centre solicitation amendment shows the practical rules. The conference let participants ask questions directly to Joint Warfare Centre personnel. The solicitation required prospective participants to provide identifying information, limited the number of representatives per bidder and made attendance costs the bidder's responsibility. The Centre also stated that a copy of the presentations and a record of the questions and answers would be published afterward for potential bidders.

Bidders' conferences in Canadian federal notices

In Canadian federal procurement, the bidders' conference is a solicitation-specific provision, not a universal mandatory step. Public Services and Procurement Canada and other departments set out the terms in each bid solicitation on CanadaBuys.

• A request for proposals for work at Prince Albert National Park states that the conference will review the scope of the requirement and answer questions. It recommends attendance by bidders intending to submit a bid.
• A CanadaBuys notice for the CCGS Vector Alongside Refit identifies an optional bidders' conference and site visit, showing how the Canadian Coast Guard uses the event for vessel work.

For complex or site-specific work, the conference may be paired with a site visit. This lets prospective suppliers inspect the work location and clarify operational or technical requirements.

What a bidders' conference means for a supplier bidding on Canadian public contracts

An optional conference does not remove your responsibility to obtain and understand the solicitation requirements. The solicitation itself controls whether attendance is required, how questions must be submitted, whether answers are binding only when incorporated by amendment and whether participation affects eligibility.

Read the solicitation for these details before planning your bid:

• The conference date, and its location or videoconference method
• The registration deadline and any attendance limits
• Security or identification requirements for attendees
• The deadline and method for submitting questions

Where the buyer recommends attendance, send someone who can ask technical questions and record the answers. Then check for an amendment that confirms what was said, and build your bid on the written solicitation.
