What CCDC documents are and who publishes them
The point of CCDC documents is consistency. Owners, contractors, consultants, and sureties across Canada all know what a CCDC 2 contract or a CCDC 221 bond actually says, because the wording is standard. That standardization is why a surety in Halifax will issue a bond on a project in Calgary without having to read a custom form, and why a contractor moving from BC to Ontario sees the same contract structure on both ends.
The CCDC contract forms carry a CCDC copyright seal on each original. Public-sector tenders typically specify that bonds and contracts must be issued on original sealed CCDC documents, not photocopies or substitute wording. Most contractors purchase blank originals through Construction Association document outlets across Canada.
You will encounter CCDC documents at three points in a Canadian construction project:
- At bid time, when you submit a CCDC 220 bid bond with your tender.
- At contract award, when the base contract (usually CCDC 2 for stipulated price work) is executed, along with CCDC 221 performance and CCDC 222 payment bonds.
- During execution, when CCDC supporting documents (statutory declarations, change orders, ready-for-takeover forms) flow between owner, contractor, and consultant.
The CCDC document directory at a glance
The full CCDC catalogue runs to dozens of contracts, guides, and forms. The ones a Canadian SMB contractor actually deals with day to day are below, grouped by what they are for.
| Form | Name | When to use |
|---|---|---|
| Pricing models | ||
CCDC 2 | Stipulated Price Contract | Lump-sum, fixed price. The default for well-defined scopes. Current edition CCDC 2-2020. |
CCDC 3 | Cost Plus Contract | Reimburse actual costs plus a fee. Used when scope is uncertain or fast-track. |
CCDC 4 | Unit Price Contract | Fixed unit rates on uncertain quantities. Common for excavation and civil work. |
| Project delivery methods | ||
CCDC 5A | Construction Management Contract for Services | Agency CM. The Owner contracts trades directly; the CM advises. |
CCDC 5B | Construction Management Contract for Services and Construction | CM-at-risk. The CM contracts the trades and delivers the Work. |
CCDC 14 | Design-Build Stipulated Price Contract | Single Design-Builder responsible for both design and construction. |
| Trade and specialty | ||
CCDC 17 | Stipulated Price Contract Between Owner and Trade Contractor for CM Projects | Trade contract used under CCDC 5A when the Owner contracts the trades directly. |
CCDC 18 | Civil Works Contract | Civil infrastructure work (highways, utilities, site servicing). |
| Bond forms | ||
CCDC 220 | Bid Bond | Submitted with the bid. Guarantees the bidder enters into the contract if it wins. |
CCDC 221 | Performance Bond | Issued at contract award. Guarantees the contractor completes the Work. |
CCDC 222 | Labour and Material Payment Bond | Issued at contract award. Guarantees the contractor pays subs and material suppliers. |
Beyond these, the CCDC publishes statutory declaration forms (CCDC 9A and 9B), bidding guides, and an Integrated Project Delivery (IPD) contract (CCDC 30) for collaborative multi-party arrangements. For an SMB contractor, the table above covers more than 95 percent of what shows up in real tenders.
CCDC 2: the workhorse Stipulated Price Contract
CCDC 2 is the contract most Canadian construction work runs on. It is a lump-sum, fixed-price agreement between an Owner and a single prime Contractor for the construction of the Work. The current edition is CCDC 2-2020, which replaced CCDC 2-2008. If a tender references CCDC 2 without specifying an edition, assume the current one and confirm in writing if the answer matters.
What CCDC 2 does:
- Locks the price. The Contract Price is fixed at award. Variations to the Work happen through formal Change Orders, not informal scope creep.
- Sets the timeline. Includes Substantial Performance, Total Performance, and warranty period definitions used by every Canadian construction lien act.
- Defines roles. Owner, Contractor, and Consultant (architect or engineer) each have prescribed duties.
- Standardizes risk allocation. Differing site conditions, delays, payment, insurance, and indemnity all have prescribed treatments. The Supplementary Conditions issued with the tender modify these for the specific project.
When a Canadian tender notice says "the contract will be on CCDC 2," that is shorthand for "you are bidding a lump-sum job under the standard Canadian fixed-price contract." If you are construction-bidding, this is the form you need to be most comfortable with.
CCDC 3 and CCDC 4: when fixed price does not fit
Two pricing models exist for the cases where a stipulated price is not feasible.
CCDC 3 (Cost Plus Contract). The Owner reimburses the Contractor for actual costs plus a fee, which can be a fixed amount or a percentage of cost. CCDC 3 is used when the scope is genuinely uncertain at contract signing, when the Owner wants to start work before design is complete, or in emergency situations. The downside is cost-control risk for the Owner; the upside is speed and flexibility.
CCDC 4 (Unit Price Contract). The Contractor bids fixed unit rates (per cubic metre, per linear foot, per tonne) on items whose final quantities are uncertain. Common in civil and earthworks where the design is solid but the dig is not, in road repair, and in utility work. The Contractor takes rate risk; the Owner takes quantity risk. Final contract value is unit rates times measured quantities.
The Owner's choice between CCDC 2, 3, and 4 is usually settled before bidding. As a bidder, your job is to read the tender, see which form applies, and price accordingly.
CCDC 5A vs CCDC 5B: agency vs at-risk Construction Management
Construction Management (CM) sits beside the prime-contractor model as an alternative project delivery method. The Owner hires a Construction Manager early, often before design is finished, to advise on constructibility, scheduling, and budget. The CM then either coordinates trades or delivers the Work. CCDC publishes two CM contracts, and which one applies to a project changes the risk allocation entirely.
| CCDC 5A | CCDC 5B | |
|---|---|---|
| What it covers | Services only (advisory and oversight) | Services plus the construction Work itself |
| Who contracts the trades | The Owner contracts trades directly | The Construction Manager contracts trades |
| CM's role | Agent of the Owner. Advises, administers, oversees. | Principal. Delivers the Work, hires and manages trades. |
| Who carries construction risk | Owner (CM is not at risk for performance) | Construction Manager (at-risk model) |
| Trade contract used | CCDC 17 (Owner-to-Trade) for each trade | The CM's own subcontract forms |
| Best for | Owners who want hands-on control with expert support | Owners who want to transfer construction risk to a single party |
The short version: 5A is agency CM. 5B is CM-at-risk. Under 5A, if a trade defaults or the schedule slips, the consequences land on the Owner. Under 5B, the Construction Manager is on the hook, the same way a prime contractor would be on a CCDC 2 job.
For trade contractors, this distinction has a direct effect. On a 5A project, you may end up contracting directly with the Owner on a CCDC 17 form. On a 5B project, you are subcontracted to the Construction Manager on their subcontract paper. Same crew, same work, different counterparty and different payment terms.
CCDC 14, 17, and 18: Design-Build, trade contracts, and civil works
Three more forms round out the contract family most SMB contractors will see.
CCDC 14 (Design-Build Stipulated Price Contract). One contract, one entity responsible for both designing and building. The Design-Builder typically holds the architect or engineer in-house or under sub. Used when the Owner wants single-point accountability and is willing to give up some design control. Common on federal and provincial transportation projects, larger institutional builds, and Owner-led P3-adjacent work.
CCDC 17 (Trade Contract for CM Projects). The trade-level contract paired with CCDC 5A. The Owner contracts a trade directly on CCDC 17 for a fixed price for that trade's scope of work, with the Construction Manager (under 5A) administering the contract on the Owner's behalf. If you are a specialty trade bidding under a 5A delivery model, this is the form you sign.
CCDC 18 (Civil Works Contract). A purpose-built contract for civil construction (highways, bridges, utilities, site servicing). Differs from CCDC 2 in details that matter for civil work: how risk is allocated for differing site conditions, how unit-price elements interact with stipulated-price elements, and how progress is measured on long-linear projects. If you are bidding road or utility work, expect CCDC 18 rather than CCDC 2 in many cases.

CCDC 220, 221, 222: the bond forms
The three CCDC bond forms run in sequence on a typical construction project.
CCDC 220 (Bid Bond) goes in with your bid. Typically 10 percent of bid value. If you win and refuse to sign, the surety pays the Owner the difference to the next-lowest bidder, up to the bond limit. If you lose, the bond is released within the bid validity period.
CCDC 221 (Performance Bond) is issued at contract award. Typically 50 percent of contract value. If you default mid-project, the surety can complete the work, hire a substitute, or pay the Owner up to the bond face value.
CCDC 222 (Labour and Material Payment Bond) is also issued at contract award, typically 50 percent of contract value, and runs in parallel with the performance bond. It gives subcontractors and material suppliers a direct claim against the surety if you fail to pay them.
Most Canadian public-sector construction tenders above $100,000 require all three. The bonds are issued on the specific CCDC forms; substitute forms even with substantially identical wording are sometimes rejected as non-compliant. We cover the full mechanics, premium ranges, and how to establish a surety facility in the dedicated guide on bid bonds vs performance bonds.
Supplementary Conditions: where buyers actually change the deal
A CCDC contract is the base text. It is intentionally not negotiable in its core wording. Owners customize the deal through Supplementary Conditions, a separate document that overrides or amends specific CCDC clauses for that project. Every federal department issues its own standard Supplementary Conditions, and so does every Crown corporation and most provincial agencies.
This is where bidders get caught. The base CCDC 2 says one thing about delay damages, or insurance, or termination, and the Supplementary Conditions in the tender package say something different. The Supplementary Conditions win on any conflict. Read them.
A working compliance review for a Canadian construction tender includes:
- Confirm the base CCDC form (which version of CCDC 2, 14, 5A, 5B, etc.).
- Open the Supplementary Conditions and read every modification. Mark anything that materially changes risk allocation, payment timing, or your obligations.
- Add each material change to your compliance matrix as its own row. (Our free compliance matrix template has a slot for exactly this; the Type column lets you tag "Supplementary Condition" alongside Mandatory and Rated.)
- Price the difference. Supplementary Conditions can shift hundreds of thousands of dollars of risk onto a bidder. That is a price input, not a footnote.
The contractors who win consistently are not the ones who memorize the CCDC text. They are the ones who read the Supplementary Conditions every single time and price what is actually being asked for. For the broader compliance read on any tender, our guide to mandatory vs desirable criteria covers the language patterns that signal pass/fail items. For the full construction-bidding sequence in which CCDC forms are step 7, see the construction pillar guide. And before committing real hours to any bid, run it through the 5-question bid/no-bid framework.
