Can I decide to sell just one location of my business and keep the others?

Yes, selling a single location while keeping the others is a common and workable structure, generally handled as a partial asset sale of that one location's assets, contracts, and (if it's a going-concern sale) its employees, while your other locations continue under your ownership as before.

The nuance is that each location usually needs to be untangled from the others individually. If a lease covers that location specifically, assigning it to the buyer generally requires the landlord's consent — and under Ontario's Commercial Tenancies Act, where the lease restricts assignment, that consent is deemed not to be unreasonably withheld unless the lease says otherwise, though the lease's own terms still control first. Shared elements — a single supplier contract covering all locations, centralized staff, or shared branding and trade name — need to be either divided or addressed separately in the purchase agreement so you don't inadvertently transfer something tied to the locations you're keeping.

Because this kind of deal has more moving parts than selling the whole business at once, it's worth having a business lawyer map out exactly what's included in the sale, review the specific lease for that location, and confirm what stays cleanly separated at the other sites.
