Can I change employee terms after buying a business?

Buyers routinely want to standardize pay grades, cut a role back, or move someone to a new location soon after closing. The mistake is assuming that because ownership changed, the old employment terms are automatically up for renegotiation. In Canadian employment law, they generally are not.

Share sale: the existing contract keeps governing

If you bought shares, the corporation is still the employer under the same contract it always had. A unilateral, significant change to pay, duties, location or status can be treated by the employee as a fundamental breach of that contract, entitling them to walk away and claim as though they had been dismissed — even though nobody used the word termination.

Asset sale: a fresh contract, but continuity still matters

An asset sale gives you the chance to set new terms from day one, because you are offering a new employment relationship rather than continuing an old one. But if the new terms are substantially worse than what the person had with the seller, and they only found out at or after closing, that can itself look like a change imposed without real consent — particularly where continuity-of-service rules treat the employment as unbroken for other purposes.

What tends to trigger a claim

• A material pay cut or a demotion introduced without the employee’s agreement
• A relocation well beyond what the original role contemplated
• Reassigning most of a person’s responsibilities to someone else while keeping their title
• Changing terms shortly after closing with no transition period or communication

The safer path

Changes that employees genuinely agree to, with something real given in exchange and enough time to consider them, hold up far better than changes simply announced. Put any change to a key term in writing, explain the business reason, and give the person a real chance to accept before it takes effect.
