Do I still get credit for my years of service when it comes to my vacation entitlement?

Yes. This is one of the clearest protections built into Ontario's continuity-of-employment rule. Under the Employment Standards Act, 2000, when a business is sold and the new owner continues your employment, your service with the seller counts as service with the buyer for the purposes of statutory entitlements — vacation time and vacation pay very much included.

Practically, that means your vacation entitlement keeps accruing based on how long you've actually worked in the business, not restarting as if you were a brand-new hire on day one with the new owner. There's one important limit worth knowing: this continuity generally doesn't apply if there's a long gap between when your work with the seller ended and when the new owner actually takes you on, so it matters that your employment genuinely continued through the transition without a real break.

If your new pay stubs or vacation balance suggest your service date has been reset to the closing date, flag that right away rather than assuming it's correct — ask HR to confirm your recognized start date in writing, since vacation calculations built on the wrong date can compound into a real shortfall over time.
