term of a contract. In Québec, it is rooted in sections 6 and 7 of the civil code which provide that "every person is bound to exercise his civil rights in accordance with the requirements of good faith" and that "no right may be exercised with the intent of injuring another or in an excessive and unreasonable manner, and therefore contrary to the requirements of good faith". It was extended to Canada's common law provinces and territories as a result of the decision of the Supreme Court of Canada in the case of Bhasin v. Hrynew. In essence, this duty requires parties to a contract to act in good faith and with honesty in exercising their rights under a contract and in delivering their obligations under a contract. This duty prohibits parties to a contract from "[lying] or otherwise knowingly mislead[ing] each other about matters directly linked to the performance of the contract”. While it is also currently an integral part of the jurisprudence of Canada's common law provinces and territories, the duty of honest contractual performance is rooted in the civil law doctrine of abuse of rights and the Supreme Court of Canada has established that precedent from Québecois contract law is applicable to interpreting this duty in cases arising in the country's common law jurisdictions and vice-versa. Consequently, in all Canadian jurisdictions, this duty is rooted in articles 6, 7, and 1375 of the Civil Code of Québec; with article 7 in particular providing that "no right may be exercised with the intent of injuring another or in an excessive and unreasonable manner". While this duty does not serve to extinguish or negate a party's rights under a contract, it serves to limit the manner in which parties to a contract may exercise their rights by mandating that parties must act in "good faith both at the time the obligation arises and at the time it is performed or extinguished". Estoppel Estoppel is an equitable remedy whereby a contracting party may not rely on the terms of a contract if, "by its words or conduct", it led the other party to believe that certain terms in the contract will be ignored, interpreted in a particular way, or given a less strict construction. One type of estoppel recognised in Canada's common law jurisdictions is estoppel by convention, which operates where three criteria are satisfied: 1) a "manifest representation" of
