A commercial lease assignment can be part of a business sale, corporate reorganization or occupancy exit, but it is not simply a change of name on the rent account. The signed lease, landlord-consent process, proposed assignee, business transaction, use, security, tax treatment and continuing obligations must be coordinated by the commercial and legal teams.
This is general information, not legal, tax, environmental, engineering, accounting or investment advice. Obtain advice specific to the property and transaction.
1. Identify the transaction and every legal party
Confirm the registered landlord, current tenant, operating business, guarantors, proposed assignee and any purchaser of business assets or shares. Obtain current corporate searches and signing-authority evidence where appropriate.
A share transaction, asset sale, amalgamation, change of control and direct lease assignment are not interchangeable. Legal and tax advisors should identify what is actually transferring and whether the lease treats that event as an assignment or other consent matter.
2. Read the assignment language before marketing the business
Review restrictions, landlord consent, notice, information requirements, recapture or termination rights, fees, change-of-control provisions, permitted transfers, conditions and the effect on guarantors. Do not promise an assignable location until counsel has reviewed the executed lease and amendments.
The wording determines the process. General statements about consent being reasonable or automatic are not a substitute for advice on the specific documents and facts.
- Consent standard
- Required documents
- Landlord fees
- Recapture or termination rights
- Change of control
- Continuing liability
3. Define exactly what the assignee receives
Prepare a complete lease package and identify the premises, remaining term, options, rent, additional rent, deposits, prepaid amounts, parking, storage, signage, exclusivity, improvement ownership, restoration and known defaults or disputes.
Separate the leasehold interest from inventory, equipment, intellectual property, licences, contracts and goodwill included in a related business sale. The business purchase agreement and lease assignment need consistent conditions and closing dates.
4. Build a qualified assignee submission
The landlord may request information to evaluate the proposed entity, principals, financial capacity, business history, use, operating plan, references, insurance and required alterations, subject to the lease and applicable law.
Provide a structured, accurate package and identify confidential fields. Alberta's PIPA governs how many private-sector organizations collect, use, disclose and protect personal information; the parties should use a secure, purpose-limited process for personal financial material.
5. Confirm use, permits and physical fit again
An existing tenant's operation does not prove that the assignee's business is permitted. Compare the proposed activities with municipal zoning, current approved use, development and building permits, business licensing and any property-specific restrictions.
Review equipment, power, ventilation, plumbing, accessibility, parking, loading, signage, fire protection and hazardous materials. Assignment consent and municipal approval are separate decisions.
6. Reconcile money, security and GST advice
Set out the assignment consideration, deposits, rent adjustments, arrears, operating-cost reconciliations, landlord review costs, security and guarantees. Confirm whether any existing deposit transfers, is refunded or remains held under the lease.
The Canada Revenue Agency treats a commercial leasehold interest as real property for GST/HST purposes and states that an assignment of that interest is generally a taxable sale, subject to the facts and registration rules. Obtain transaction-specific tax advice before setting the closing statement.
7. Document consent, assumption and liability
The document package may include landlord consent, assignment and assumption, lease amendment, new guarantee, estoppel, indemnity and related business-sale documents. Legal counsel should determine the correct structure and which obligations remain with the assignor or guarantor.
Do not describe the assignor as released unless the executed documents expressly produce that legal result. Consent to occupancy and release from liability are different questions.
8. Coordinate closing and operational handover
Use a closing checklist for landlord consent, business-sale conditions, funds, insurance, licences, permits, keys, access systems, utilities, equipment, records, inventory, employee communication and possession.
Record meter readings and premises condition, identify incomplete landlord or tenant work and deliver final executed documents to every party. Update the critical-date schedule under the assigned lease.
