What is the Buy Canadian Policy? A plain-language explainer

If you sell to the federal government, you have probably heard the phrase "Buy Canadian" a lot lately. It is not just a slogan. Since December 2025, it is a real set of rules that change how some federal contracts are scored and who can bid on them. This guide explains what the policy actually says, who it affects right now, and what is still to come.

What the Buy Canadian Policy actually is

The Buy Canadian Policy is a federal government rule that gives Canadian-based suppliers an advantage when their bids are scored on certain contracts. It does not ban foreign suppliers outright. Instead, it changes the scoring so that being a Canadian supplier, or offering Canadian-made goods, earns extra points or better standing during evaluation.

Think of it as a thumb on the scale, not a locked door. A foreign supplier can usually still bid. But a Canadian competitor with a similar price and quality will often come out ahead once the Canadian advantage is applied.

The policy grew out of two pressures hitting Canadian businesses at once. Trade disputes and tariffs have made it harder for some Canadian firms to sell into other markets, squeezing their revenue. At the same time, the federal government wanted procurement dollars to do more to support jobs and manufacturing at home. The result is a policy that steers federal buying power toward Canadian suppliers where the rules allow it.

Who the policy applies to right now

The Buy Canadian Policy is being rolled out in stages, not all at once. As of mid-2026, it applies to what the government calls strategic sectors — industries considered important to national economic or security interests, such as defence, critical minerals, steel, aluminum, and advanced manufacturing.

Here is the part that matters most for small business owners: the policy currently only applies to large contracts. A dollar threshold decides which contracts are covered.

Milestone	Contract value threshold	Status
December 2025 launch	$25 million or more, strategic sectors	In effect
Mid-2026 expansion	$5 million or more, strategic sectors	Rolling out
Small Business Procurement Program	Proportional requirements, smaller contracts	Rolling out through 2026
Reciprocal procurement rules	Most non-defence federal contracts	Starting spring 2026

If your business bids on smaller federal contracts today, the strategic-sector rules may not touch you directly yet. But the threshold is coming down, and a separate small business stream is being built alongside it. Both are worth watching even if neither applies to you this month. You can track which live opportunities carry Buy Canadian conditions through live tender search, where notices are flagged as they are published.

Canadian content rules: what "Canadian-made" actually means

Alongside the scoring advantage, some large projects now carry Canadian content rules. These are minimum-percentage requirements for how much of a product must be made, processed, or sourced in Canada before it counts as Canadian for procurement purposes.

Right now, these rules focus on three materials: steel, aluminum, and wood, used on large infrastructure and construction projects. If you supply or install building materials, this is the part of the policy that will hit your bids first, not the general scoring advantage.

Canadian content rules can get technical fast. A product assembled in Canada from imported parts might not qualify. A product processed abroad from Canadian raw materials might not qualify either. The exact test depends on the contract and the material. If your business works with steel, aluminum, or wood on public projects, it is worth reading what "Canadian content" requirements actually mean under the new Buy Canadian rules before you price your next bid, so you are not caught out by a requirement buried in the technical specifications.

The Small Business Procurement Program

The strategic-sector rules mostly affect large contracts and large suppliers. To make sure small businesses are not left out, the government is rolling out a Small Business Procurement Program through 2026.

This program works on proportional requirements. Instead of asking every supplier to meet the same fixed Canadian-content percentage regardless of size, requirements can scale to fit smaller businesses and smaller contracts. The goal is to open a path for small and medium firms that would struggle to meet the same rules built for a multinational contractor.

Two other pieces are launching alongside it:

• A shared "Tell Us Once" attestation system. An attestation is a formal statement you sign confirming certain facts about your business, such as where your goods are made. "Tell Us Once" means you submit that information a single time and reuse it across multiple bids, instead of re-declaring it on every tender.
• Plain-language tender summaries, which give a short, jargon-free overview of what a contract needs before you dig into the full technical documents.

Both changes are designed to cut the paperwork burden that keeps smaller firms from bidding in the first place.

Reciprocal procurement: a bigger change coming in spring 2026

Separate from the Canadian-content rules, reciprocal procurement rules are set to start in spring 2026. "Reciprocal" means the access works both ways: Canada opens its contracts to a country's suppliers only if that country opens its contracts to Canadian suppliers in return.

In practice, this restricts most non-defence federal contracts to Canadian suppliers and suppliers from trusted-partner countries — nations that give Canadian firms similar access to their own government contracts. Suppliers from countries that do not offer that reciprocal access may find themselves excluded from bidding altogether on affected contracts, not just scored lower.

This is a bigger shift than the scoring advantage in the original Buy Canadian Policy, because it can rule bidders out entirely rather than just ranking them behind Canadian competitors. If your supply chain depends on components or subcontractors from outside Canada, it is worth understanding this change well before spring 2026. A closer look is available in reciprocal procurement explained — what it means for suppliers in 2026.

What this means for your bid strategy

None of these rules matter unless you translate them into decisions about which tenders to chase and how to price your bids. A few practical starting points:

• Check the contract value against the thresholds. A $3 million contract today sits below the strategic-sector rule, but that will not last through 2026 as the threshold drops.
• Know your supply chain. If your materials or subcontractors come from outside Canada, work out now whether that exposes you under the Canadian content rules or the coming reciprocal rules.
• Watch for the small business stream. If your firm is small, the proportional requirements under the Small Business Procurement Program may be easier to meet than the general rules.
• Read the fine print on every notice. Buy Canadian conditions are being written into individual tender documents, not just a general policy statement, so the details vary by contract.

You can browse live opportunities filtered by sector and province through opportunity landing pages by category and province, and check who is buying through buyer and agency profiles before you commit time to a bid.

A policy still taking shape

The Buy Canadian Policy is not finished. Thresholds are still dropping, the small business stream is still rolling out, and reciprocal procurement rules have not yet taken effect. Provinces are also removing barriers to trade between each other, which is a related but separate shift worth watching if you sell across provincial lines.

The businesses that come out ahead will be the ones that check the rules on every contract rather than assuming they know how the policy applies.
