Bid Opening Explained
Learn how government bid openings work in Canada, including public and private bid openings, the rules governing them, and what happens after bids are opened.

Introduction
Bid opening is a critical step in the government procurement process. It is the moment when submitted bids are formally opened and recorded. Understanding how bid openings work helps you know what to expect and confirms the transparency of the process. This guide explains bid opening procedures in Canadian government procurement, including the differences between public and private openings, and what happens after bids are opened.

What Is Bid Opening?
Bid opening is the formal process of opening and recording bids after the closing date and time has passed. The purpose is to ensure transparency and accountability in the procurement process.
The bid opening process typically includes:
- ✓Confirming the closing date and time has passed
- ✓Opening each bid in accordance with the solicitation instructions
- ✓Recording key information from each bid
- ✓Preparing an official record of bids received
- ✓Safeguarding bid documents for evaluation[/Checklist
]
Pro Tip
Bid opening is a procedural step, not an evaluation. At this stage, bids are opened and recorded, but they are not yet scored or compared.
Public vs Private Bid Openings
There are two main types of bid openings:
**Public Bid Opening:** In a public bid opening, suppliers and other interested parties can attend to observe the process. The buyer reads out key information such as bidder names and total prices. Public openings are common for construction tenders and ITT-style procurements.
**Private Bid Opening:** In a private bid opening, only procurement officials are present. The bids are opened and recorded internally. Private openings are common for complex RFPs where price is only one factor.
- ✓Public openings: Used for ITTs and construction tenders. Suppliers can attend. Prices are announced.
- ✓Private openings: Used for RFPs and complex procurements. Only officials attend. Information remains confidential until award.[/Checklist
]
Warning
Even in public bid openings, not all information is shared. Detailed technical proposals remain confidential. Only basic information like bidder name and total price is typically read out.[/Warning
]
Rules Governing Bid Openings
Bid openings are governed by strict rules:
- ✓Timing: Bids are opened immediately after the closing date and time — no exceptions
- ✓Late bids: Late bids are almost never opened or accepted
- ✓Recording: All bids received are recorded, including those deemed non-compliant
- ✓Confidentiality: Unopened bids are kept secure before the opening
- ✓Integrity: The process must be conducted by authorized personnel following established procedures[/Checklist
] The rules are designed to ensure every supplier is treated fairly and the integrity of the process is maintained.
What Happens After Bid Opening?
After the bid opening, the procurement process continues:
1. **Compliance Check**: Each bid is reviewed for compliance with mandatory requirements.
2. **Non-Compliant Bids**: Bids that fail mandatory requirements are set aside and not evaluated further.
3. **Evaluation**: Compliant bids proceed to evaluation, where they are scored against the published criteria.
4. **Clarification**: The buyer may seek clarification from bidders on specific points (but cannot change the bid).
5. **Award Decision**: The evaluation team recommends the winning bid.
6. **Notification**: All bidders are notified of the award decision.

Pro Tip
Do not assume your bid is compliant just because it was opened. Bid opening only confirms your bid was received on time. Compliance checking happens next.
Can You Attend a Bid Opening?
Whether you can attend a bid opening depends on the solicitation:
- ✓Solicitations that specify "public bid opening": Yes, you or your representative can attend
- ✓Solicitations with "private bid opening": No, attendance is restricted to officials
- ✓Construction contracts: Typically public openings
- ✓RFP procurements: Typically private openings[/Checklist
] If you want to attend, check the solicitation documents for details on the bid opening procedure. If it is public, the time and location (or virtual meeting link) will be specified.
Summary
Bid opening is the formal process of opening and recording bids after the closing date. Public openings allow suppliers to attend and hear basic bid information. Private openings are conducted internally. After opening, bids are checked for compliance and then evaluated. Understanding the bid opening process helps you know what to expect and confirms the transparency of government procurement.
