Policy Version Control in Canada: What Employers Must Do to Prove Which Policies Applied

An employee was hired in 2023. At the time, the company's vacation policy offered two weeks of paid vacation after one year of service. In 2025, the policy was updated to three weeks after two years. The employee, now past the two-year mark, requests three weeks. The employer believes the original policy applies. The employee believes the updated version does. Neither side can prove which version was in effect when the employee reached the eligibility threshold. The employer updated the policy — but overwrote the previous version. There is no record of when the change was made, no version history, and no evidence that the employee received or acknowledged either version. This is not a policy problem. It is a version control problem. And for most small and mid-sized Canadian employers, it is entirely unaddressed. Policy version control becomes a compliance issue whenever: You update workplace policies without assigning version numbers or tracking changes You distribute updated policies by overwriting the previous document — whether as a PDF, shared file, or printed handbook You do not track which employees received which version of a policy You have no system for recording employee acknowledgment of updated policies If any of these describe your current process, your ability to defend your policy position during a dispute is significantly weakened. Maintaining defensible policy records requires tracking the following elements for every policy document: Version number — A unique identifier for each version of the policy (e.g., v1.0, v1.1, v2.0) Effective date — The date on which the policy version takes effect Change history — A record of what was changed between versions — additions, removals, or modifications Distribution — A record of which employees received the updated version and when Acknowledgment — Confirmation that each employee reviewed and accepted the policy version Without these elements, an employer cannot reliably demonstrate which policy governed a specific situation at a specific time. Canadian employment standards legislation already requires employers to maintain specific records, and these obligations reinforce why version control matters: In Ontario , employers must retain specified employment records for prescribed periods, with different retention triggers depending on the type of record (Employment Standards Act, 2000, section 15). Ontario also requires employers with 25 or more employees in Ontario on January 1 to have written policies on disconnecting from work and electronic monitoring, and to retain copies of those policies for three years after they cease to be in effect. In Alberta , employers must retain employment records for at least three years from the date each record is made (Employment Standards Code, section 15). In British Columbia , employers must keep payroll records as required under section 28 of the Employment Standards Act. In Saskatchewan , employer recordkeeping obligations are set out in section 2-38 of The Saskatchewan Employment Act. In Manitoba , section 135 of the Employment Standards Code requires employers to maintain employee records. Under the federal Canada Labour Code , employers must keep a record of hours worked by employees each day and amounts paid in overtime. While these provisions do not all explicitly require "policy version control," they establish a clear expectation: employers must maintain accurate, retrievable records that can demonstrate what applied and when. An employer who cannot produce the version of a policy that was in effect at a specific time is at a significant disadvantage in any dispute. A small manufacturing company in British Columbia updates its vacation policy annually. Each update is saved over the previous file. The company does not maintain archived copies, does not assign version numbers, and does not track which employees received which version. An employee hired in 2022 disputes their vacation entitlement after a policy update in 2024. The employer believes the 2022 version applies based on the employee's hire date. The employee argues the 2024 version should apply because it was the most recent policy communicated to them. Under BC's Employment Standards Act, employers must provide employees with at least 2 weeks of vacation after 12 consecutive months of employment, and at least 3 weeks after 5 consecutive years (section 57). However, the employer's own policy may offer additional entitlements beyond the statutory minimum — and in a dispute about those additional entitlements, the employer's ability to prove which version was in effect is critical. The employer cannot produce the 2022 version. There is no record of when the 2024 version was distributed. There is no acknowledgment on file for either version. The employer's position — that the earlier version governs — is effectively unverifiable. Without version records, the dispute becomes a matter of competing claims rather than documented fact.
