Electronic Bid Submission Deadline

An Electronic Bid Submission Deadline is the specific date and time by which a supplier must submit its bid electronically, using the procurement system or method named by the buyer. It is a fixed point in the procurement timetable. A bid that arrives after that point may be rejected or treated as non-responsive.

The deadline usually appears on the cover page or in the timetable of a solicitation, and it is tied to a required submission channel such as an electronic procurement portal. Related expressions include bid submission deadline, tender submission deadline, deadline for bid submission and closing date. In Canadian federal solicitations the same idea is most often written as the Closing Date.

How Canadian federal solicitations state the deadline

Federal documents rarely use the exact capitalized phrase, but they apply the concept firmly. A request for proposals published on CanadaBuys states that bids must be received by the date and time shown on the cover page, which it calls the Closing Date. It also states that bids received after that date are considered non-responsive and are not considered for contract award. You can see the wording in this CanadaBuys federal RFP.

An invitation to tender from Natural Resources Canada uses slightly different language. It requires bids to be submitted no later than the date and time indicated on page 1 of the bid solicitation, as shown in the NRCan invitation to tender. The wording differs, but the rule is the same: the stated date and time govern.

Dates the deadline should not be confused with

The submission deadline is a separate item from other dates in a solicitation. Keep it distinct from:

• the deadline for submitting supplier questions to the buyer;
• any contract-performance or delivery deadline; and
• the bid-validity period, which concerns how long a bid stays open for acceptance.

Meeting one of these dates does not satisfy another. A supplier that asks a question on time has not met the submission deadline, and a bid with a long validity period still has to arrive before the closing time.

Submission channels and the Ariba requirement

The deadline only counts when the bid is submitted through the channel the buyer specifies. Public Services and Procurement Canada (PSPC) tells suppliers to verify both the method and the deadline for submission in its bidding guidance. For opportunities processed through the electronic procurement solution, bids must be submitted through SAP Ariba.

PSPC also provides guidance on submitting bids electronically through the Ariba platform on its bid on opportunities page. Suppliers who plan to bid on these opportunities should read it before a live deadline is in play.

The same rule in allied procurement

Other jurisdictions treat the end of the bidding period the same way. UK guidance under the Procurement Act 2023 describes the tendering period as ending on the day by which tenders must be submitted. It sets different minimum periods depending on whether tenders are submitted electronically, as set out in the UK time periods guidance. A UK defence-related procurement attachment likewise instructs bidders to submit through the stated e-sourcing portal before the closing date and time, and warns that late bids will not be considered.

What it means for a supplier bidding on Canadian public contracts

Treat the closing date and time as absolute. Find it on the cover page or page 1 of the solicitation, confirm the submission method, and complete the bid early enough that the electronic submission is received before the deadline. Do not wait for the final minutes to upload documents or resolve access problems.

A late bid risks being declared non-responsive, which means it is not considered for award regardless of its price or technical merit. Check each solicitation for its own wording, since federal documents use terms such as Closing Date or the date and time indicated rather than one standard phrase.
