How to bid on tender opportunities

Once you have registered your business and found a tender opportunity that interests you, you can start the bidding process. Each tender notice will clearly indicate the delivery method you must use to submit a bid.

The CanadaBuys tendering service displays tender notices from:

  • Public Services and Procurement Canada (PSPC)
  • other Government of Canada departments and agencies
  • the broader Canadian public sector
  • the NATO Support and Procurement Agency

The Organization column of the table on the Tender opportunities page will indicate which organization has posted the tender notice.

Opportunities from Public Services and Procurement Canada

PSPC uses SAP Ariba to post tender notices on behalf of other federal departments and agencies and Crown corporations. To bid on a tender opportunity posted in SAP Ariba, check out these how-to guides to help you through the process:

Tender opportunities from the following organizations from across the Canadian public sector are included on CanadaBuys:

  • Provincial and territorial governments
  • Municipalities
  • Publicly funded academic institutions
  • Schools
  • Hospitals
  • Crown corporations

The bidding details of a tender notice will include a link to the organization’s website, where you will find detailed instructions on how to bid.

Opportunities from the NATO Support and Procurement Agency

CanadaBuys also posts tender notices from the NATO Support and Procurement Agency (NSPA). To find them, use the "NATO – North Atlantic Treaty Organization" filter on the CanadaBuys Tender opportunities page.
