    The closing date listed on CanadaBuys is not fixed and serves primarily for administrative purposes, allowing adequate time for all procurement stages to be completed and adjustments to be made as needed throughout the agile solicitation process. However, it is imperative for bidders to understand that certain 'closing dates' are critical and must be strictly adhered to in order to be part of the evaluation process. These critical stages include, the Prequalification Closing Date (Stage 4), Demo Registration Limit date (Stage 7), and Challenge-Based Solicitation (CBS) Closing Date (Stage 8), each playing a pivotal role in the evaluation of bids. Bidders are encouraged to regularly visit the CanadaBuys website, where deadlines and documents will be updated as the procurement process progresses.

    After the prequalification stage, communication will be limited exclusively to those who have successfully prequalified, and further details will no longer be shared publicly on CanadaBuys.
