You want to know a secret? Every time you hire a contractor to do some construction or renovation work on your property, you must hold back from the contractor 10% of the contract price until 45 days after the work has been completed. This retained sum is called โ€œholdbackโ€ and it is the law in Ontario pursuant to the Construction Lien Act, R.S.O.1990, c.C. 30, (the โ€œActโ€) and in most other provinces and territories with slight variations.

It is a secret because it is the rare contractor that will inform you of this obligation. However, if you do not hold back 10% of the contract price, an unpaid subcontractor or supplier can tie up the title to your property by registering a Claim for Lien that will prevent you from selling, refinancing or otherwise dealing with the property until the lien is removed. The owner of the property will not be allowed to remove the Claim for Lien from the title until they have paid that 10% portion of the contract price to the lien claimant โ€“ even if the owner has already mistakenly paid it out to the contractor. Thus, you may end up paying it twice: once to the contractor and once to a lien claimant.

The holdback obligation applies to all contracts with an owner, contractor, or subcontractor for the supply of services or materials to an improvement on the land of the owner. The building, repair, renovation, or even demolition of a barn or other farm building is an โ€œimprovementโ€ under the Act. Any renovation to your home is an โ€œimprovementโ€ โ€“ even that simple paint job in your living room. In each of these cases, the 10% holdback must be retained.
