Maintenance & Warranty Bonds for Canadian Construction
Guarantee long-term quality and defect-free execution beyond handover. ContractBonding.ca helps Canadian contractors secure maintenance and warranty bonds that satisfy stringent owner specifications.
Protecting Project Quality After Substantial Performance
In Canada, the conclusion of physical construction marks the beginning of the warranty period. While a Performance Bond guarantees that a facility is built according to plans, a Maintenance Bond (often referred to as a Warranty Bond) guarantees that it performs as intended and remains free of workmanship or material defects.
If latent defects emerge during the bonded warranty term—such as roof membrane failure, foundation settlement, or mechanical malfunction—the contractor is legally required to perform corrective repairs. If the contractor is unable or fails to do so, the Surety steps in to fund the repairs up to the penal sum of the bond.
Holding established bonding capacity allows general and mechanical contractors to furnish required warranty securities without encumbering bank borrowing facilities or withholding substantial cash reserves.
