When a creditor seeks to enforce a personal guarantee, they must navigate a structured legal process that requires them to establish certain foundational elements before any court will order the guarantor to pay. Understanding this process matters enormously for business owners, sole proprietors, and non-profit operators who have signed guarantees, because knowing what a creditor must prove—and where their proof might fall short—can mean the difference between facing full liability and successfully defending against an enforcement action. Equally important, understanding the enforcement process helps those who hold guarantees from others appreciate what steps they must take to recover amounts owed to them.
The enforcement of a personal guarantee begins with the premise that the creditor bears the burden of proof. In Canadian law, this means the party seeking to enforce the guarantee must demonstrate, on a balance of probabilities, that all necessary conditions for enforcement have been satisfied. This burden never shifts to the guarantor, though the guarantor may raise defences that require their own evidentiary support. The creditor's obligation to prove their case stems from fundamental principles of contract law that apply across all Canadian jurisdictions, including both the common law provinces and Quebec under the Civil Code of Quebec. In Quebec, as of the date of authorship, suretyship is governed by articles 2333 to 2366 of the Civil Code of Quebec, which establish requirements that parallel but do not precisely mirror those in common law provinces. Understanding these requirements helps Canadian business people appreciate what they may face regardless of where they operate.
