Part (a) — bid bonds compared with performance bonds. Both instruments are surety bonds, and it is worth being precise about what that means before comparing them, because the point is regularly lost. A surety bond is not insurance. Insurance is a two-party contract in which the insurer pools and absorbs the insured's losses and expects, on average, to pay claims out of premium. A bond is a three-party instrument — principal (the contractor), obligee (the owner) and surety — in which the surety guarantees the principal's obligations to the obligee, expects no losses at all because it underwrites the contractor's capacity rather than a statistical risk, and retains a right of indemnity against the principal for anything it does pay. The premium is therefore better understood as a fee for the extension of credit and for the underwriting judgement behind it, and a contractor's bonding capacity is a statement about its balance sheet, its track record and its management depth.

The bid bond attaches to the tendering phase. It guarantees that if the contractor's bid is accepted within the stipulated irrevocable period, the contractor will enter into the contract at the price bid and will furnish whatever further security the tender documents require. Its penal sum is a fraction of the bid, in Canada conventionally ten per cent, and the surety's exposure is limited to the owner's damages from the default — in practice the difference between the defaulting bid and the next acceptable one, capped at the penal sum. It has a short life, expiring when the contract is signed or when the irrevocable period lapses, and its practical function is twofold: it makes the tender price genuinely irrevocable and so protects the integrity of the bidding process, and, because the surety will only issue it after underwriting, it pre-screens bidders for financial capacity before the owner ever opens the envelopes. Under Canadian tendering law — the Contract A / Contract B analysis established in Ron Engineering and refined in M.J.B. Enterprises and Double N Earthmovers — submission of a compliant bid forms a preliminary contract, and the bid bond is the security for the bidder's obligations under it.

The performance bond attaches to the construction phase and is a different animal in scope, size and duration. It guarantees the contractor's performance of the construction contract itself, so its penal sum is a percentage of the contract price — fifty per cent is the Canadian norm on public work, with one hundred per cent used where the owner wants full coverage — and it stays in force through the work and typically through the warranty period. On a declared default the surety's options are broader than simply writing a cheque: it may finance the existing contractor to completion, tender the remaining work to a replacement contractor and pay the excess cost, take over and complete the work itself, or pay the owner its ascertained damages up to the penal sum. Those options are precisely why owners value the instrument — the surety brings completion capability, not merely money. In Canada the performance bond is almost always issued alongside a labour and material payment bond, usually also at fifty per cent, which protects subcontractors and suppliers rather than the owner and is the reason a general contractor's default does not automatically cascade down the supply chain.

The essential differences can be stated compactly. They cover different phases (tender versus construction) and different obligations (entering into the contract versus performing it). Their penal sums differ in both base and magnitude — a fraction of the bid price versus a large fraction of the contract price — so a performance bond is an order of magnitude larger in exposure. They differ in duration, days or weeks against years. They differ in the surety's remedy, damages capped at the penal sum in one case against a menu that includes completing the work in the other. And they differ in what triggers them: refusal to execute the contract, against a formally declared default under the construction contract, which under CCDC 221/222 requires notice and a cure opportunity. What they share is the three-party structure, the surety's indemnity against the contractor, and the underwriting that makes the contractor's bondability a real constraint on how much work it can carry at once.

Part (b) — the purpose and mechanics of construction liens. A construction lien — called a builders lien in British Columbia and most western provinces, a construction lien in Ontario, and a legal hypothec in Quebec — is a statutory charge against the improved land in favour of anyone who supplies work or material to the improvement. Its purpose is to solve a structural problem in the construction supply chain: a subcontractor or supplier has no contract with the owner, and so at common law would have no claim against the owner or the land, yet its labour and material have permanently increased the value of that land. The legislature's answer is to give the unpaid claimant security in the very asset its work has enhanced, so that payment risk does not simply fall on the party furthest from the money. A second, equally important purpose is prophylactic: because a registered lien clouds title and blocks both financing draws and sale, the mere existence of the remedy pushes payment down the chain far more often than it is actually exercised.

The mechanics rest on two connected devices. The first is the lien itself. A claimant who supplies work or material to an improvement acquires the right on commencing that supply, and perfects it by registering a claim of lien in the land title office against the affected parcel within the statutory period — in British Columbia, forty-five days from the issue of a certificate of completion for the relevant contract or subcontract, or from substantial performance, abandonment or termination of the head contract, whichever comes first. Ontario's period is sixty days under its modernised statute, and the periods vary province to province, which is why the first question on any lien problem is which province's Act governs. The lien attaches to the owner's interest in the land and, on a leasehold or a Crown project where the land itself cannot be liened, to the holdback funds instead. Registration alone does not preserve the claim indefinitely: the claimant must commence an action to enforce the lien and register a certificate of pending litigation within a further statutory period — one year in British Columbia — or the lien expires. The owner or contractor can clear title without conceding the claim by paying the amount into court or posting a lien bond, which substitutes a fund for the land as security and lets the project financing proceed.

The second device is the statutory holdback, and it is what makes the scheme workable rather than ruinous for owners. The payer must retain a fixed percentage of the value of the work — ten per cent in British Columbia and in most Canadian jurisdictions — in a separate holdback account, and must keep retaining it from every progress payment until the lien period has expired without a claim being filed. The holdback is a fund against which lien claims are satisfied, and the crucial consequence is that an owner who has properly retained and preserved the holdback has a limit on its exposure: it cannot generally be made to pay twice for the same work, and its liability to unpaid claimants down the chain is confined to the holdback plus any amount still owing to the contractor. An owner who pays out the holdback early loses that protection entirely. The statutes reinforce all of this with a trust regime — funds received on account of the price of the work are impressed with a trust in favour of those who supplied it, and a director or officer who diverts them can be personally liable — and, in British Columbia, with a shoring-up mechanism whereby the lien of a subcontractor is limited to what is owed up the chain. For an engineer administering a contract the practical rules follow directly: certify accurately, verify that the holdback is being retained in the correct account, obtain statutory declarations from the contractor confirming that subtrades have been paid before releasing progress payments, run a title search before releasing the holdback, and never release it before the lien period has run.
