When a federal department believes only one supplier can meet their needs, they can't just hand over a contract quietly. The Advance Contract Award Notice Response Period is that mandatory 15-day window where they post their intention publicly and wait to see if anyone else steps up to challenge the sole-source decision. Think of it as the government's way of saying "we think only Supplier X can do this—prove us wrong."
How It Works
According to the Supply Manual Chapter 3.3, the process starts when a contracting authority posts an ACAN on the government electronic tendering service. The notice includes details about what they need and why they believe only one supplier can deliver. Then the clock starts ticking.
Fifteen calendar days. Not business days—calendar days, which matters when you're racing against a deadline that might include weekends and holidays.
During this period, other suppliers can submit a Statement of Capabilities demonstrating they can actually meet the requirement. Here's the thing: if even one valid statement comes in that meets the posted criteria, the whole sole-source approach collapses. The contracting authority must then move to a competitive bidding process. But if the 15 days pass without a qualifying challenge? The Treasury Board Contracting Policy section 12.3.2 is clear—the resulting contract is deemed competitive, even though only one supplier was ever seriously considered.
In practice, this mechanism serves a dual purpose. It satisfies transparency requirements while giving departments access to higher contracting limits normally reserved for competitive processes. PSPC and other departments use ACANs regularly for everything from specialized IT services to unique scientific equipment where genuine alternatives may not exist. The response period protects market access without forcing artificial competition where it doesn't make sense.
Key Considerations
- Calendar days means calendar days. Suppliers have complained about ACANs posted just before long weekends, giving them less practical time to respond. If you're monitoring these notices, plan accordingly.
- Your Statement of Capabilities needs to address every requirement. Contracting authorities aren't required to negotiate or seek clarification. If your submission doesn't clearly demonstrate you can meet what's in the ACAN, it won't trigger a competitive process.
- The 15-day minimum is exactly that—a minimum. Departments can extend the period, though they rarely do. Some complex requirements might warrant asking for more time before the posting period ends.
- No response doesn't mean no one was watching. Even ACANs that proceed to contract get scrutinized in Procurement Ombudsman reviews and procurement practice audits. Departments at DND and SSC have faced questions about whether their sole-source justifications truly held up.

If you're tracking opportunities in your sector, set up alerts for ACANs and move fast when they appear. Fifteen days goes by faster than you think, especially when you're gathering evidence that you can deliver.
