The Extension Request Letter is a crucial business document used when one party needs to formally request a modification to existing timelines or deadlines in a contract or agreement under Canadian jurisdiction. This document is typically employed when unforeseen circumstances, project complexities, or other valid reasons necessitate an extension of the original timeline. The letter should include specific details about the current situation, justification for the extension, proposed new timeline, and measures to mitigate any potential negative impacts. It serves as an official record of the request and forms part of the contract documentation, requiring careful attention to detail and compliance with Canadian contract law principles and provincial regulations. The Extension Request Letter is particularly important in maintaining professional relationships while seeking necessary timeline modifications in a formal, documented manner.
