Official sources: change orders and extra work

How to use this list

These are official government and court sources for change orders and extra work, grouped by province and territory. ArtBuild checked each link on the date shown. Always read the current official version for your project; laws and forms change.

Your province or territory decides most of the rules: liens, holdback, prompt payment, consumer protection and the courts. Federal law adds bankruptcy and insolvency, and prompt payment on federal property.
