Tired of procurement pain? Our AI-powered platform automates the painful parts of identifying, qualifying, and responding to Canadian opportunities so you can focus on what you do best: delivering quality goods and services to government.
Buyandsell.gc.ca
The Government of Canada's official electronic tendering service where federal contracting opportunities are posted and where suppliers can search, view, and download solicitation documents for open competitions.
Buyandsell.gc.ca is the Government of Canada's official electronic tendering service—the digital marketplace where federal contracting opportunities live and breathe. If you're trying to do business with federal departments or you're a procurement officer managing competitions, this is your daily workspace. According to the Supply Manual Section 2.2, this is where suppliers search, view, and download solicitation documents for open competitions across all federal entities.
How It Works
The platform serves two distinct audiences. For suppliers, it's a searchable database of active tenders, historical contracts, and current standing offers and supply arrangements. You can filter by commodity code, department, or value threshold to find opportunities that match your capabilities. When PSPC or DND posts a Request for Proposal, it appears here—usually within hours of approval.
Here's the thing: federal procurement officers use a separate layer of functionality. The Standing Offers and Supply Arrangements Application (SOSA App) is exclusively available to government users for searching and managing these instruments. Staffing up a project at SSC or Treasury Board and need to source professional services quickly? The SOSA App lets you identify which standing offers apply and who the qualified suppliers are. This matters for low dollar value procurements—those under $25,000 for goods and $40,000 for services—where you're required to use existing vehicles rather than running a full competition.
The platform also maintains historical data. Contracts awarded last quarter? Archived here. That supply arrangement PSPC established for cloud services three years ago? Still searchable. This creates transparency but also gives competitors insight into who's winning what—and at what price points. You'll find procurement professionals mining this data to benchmark their own solicitations or identify potential bidders for upcoming work.
Key Considerations
Mandatory usage for specific commodities: Certain goods and services can only be procured through standing offers and supply arrangements listed on the platform. You can't just go direct to a supplier, even if you have a relationship. The system enforces this through departmental compliance reviews.
Document version control matters: Amendments to solicitations get posted as separate files. Downloaded the original RFP two weeks ago but missed Amendment 003? Your proposal might be non-compliant. Check the document list before every submission.
Historical contract data has limitations: While you can see award values and suppliers, you won't always get the full picture of negotiations, options exercised, or task authorizations under standing offers. The posted value is often just the initial commitment.
Access levels differ significantly: What suppliers see versus what federal users access through the SOSA App are fundamentally different experiences. Don't assume a supplier can navigate the same way you do internally.
