Construction tenders in Canada: what to check before you bid
Construction and maintenance tenders reward careful reading. Small details such as bid security, an addendum or a missed site visit can disqualify a bid that was otherwise competitive.
Reviewed October 2026 against the official sources listed below. Independent guide, not affiliated with the Government of Canada. Rules and programs change, so confirm details in the official notice.
What these notices usually contain
- A description of the work, the location and the contract term.
- Mandatory requirements, often including insurance, licences and relevant experience.
- Bid security or bonding requirements, which are common in construction. Read exactly what the notice asks for and when.
- A site visit or information session, sometimes mandatory, with a fixed date.
- Instructions for questions and for addenda that change the documents.
Before you commit time
- Confirm you can meet every mandatory requirement and the schedule.
- Check whether the bid must be priced as a lump sum or by unit.
- Check bonding and insurance capacity with your broker well before the closing date.
- Read the health and safety and security conditions.
- Note the closing time and time zone, and plan to submit early.
Track the moving parts
Most missed opportunities come from dates and paperwork, not pricing. Keep the site-visit date, the question deadline, each addendum and the closing time in one place for every notice you pursue.
