Governed by the Landlord and Tenant Act (R.S.N.B. 1973, c. L-1), which became effective on December 31, 1973, commercial leases in New Brunswick operate under a framework distinct from residential law. Unlike residential tenancies, where the government mandates a strict "Standard Form of Lease," the commercial real estate market in New Brunswick is entirely unstandardized. There is no single required form, meaning every commercial lease must be painstakingly reviewed and custom-drafted.

No Standard Mandatory Form

Because businesses range from small retail boutiques to massive industrial warehousing, a "standard" commercial lease does not exist. The law assumes both the landlord and the commercial tenant have adequate access to legal counsel to negotiate terms that suit their specific operational requirements.

The commercial lease agreement itself acts as the primary governing law regarding the relationship between the two parties. If an issue is not covered in the lease, landlords must rely on general principles of contract law and the Landlord and Tenant Act.

Critical Clauses to Include

To protect a commercial investment in New Brunswick, a well-drafted lease should address the following extensive requirements:

1. Financial Obligations (Base and Additional Rent)

Clearly define the financial structure. If the lease is a Triple Net (NNN) lease, explicitly detail the tenant's responsibility to pay their proportional share of Common Area Maintenance (CAM), property taxes, and insurance.

2. Permitted Use Exclusivity

  • The Landlord: Must ensure the "Permitted Use" clause is narrow (e.g., "for the sale of men's clothing") rather than broad ("for retail sales"). If the tenant pivots their business model, a narrow clause allows the landlord to reject the change.
  • The Tenant: Often demands an "exclusivity clause" preventing the landlord from leasing another unit in the same strip mall to a direct competitor.

3. Maintenance and Repair Responsibilities

Avoid vague terms like "good repair." The lease must explicitly list who is responsible for the foundation, the roof, exterior walls, HVAC replacement, interior plumbing, and daily janitorial services. Do not simply copy-paste a maintenance clause from a different property; tailor it to the specific building's age and condition.

4. Assignment and Subletting

Commercial tenants frequently sell their businesses. The lease must detail the landlord's right of consent regarding a lease assignment. Landlords typically include clauses stating that even if the lease is assigned to a new buyer, the original tenant (and their personal guarantors) remain liable for the rent if the new buyer defaults.

5. Default and Remedies

Right of Re-entry for Non-Payment of Rent or Breach of Covenant:

Under the Landlord and Tenant Act (R.S.N.B. 1973, c. L-1):

  • Section 9(1): In every lease, unless otherwise agreed, there is an implied agreement that if rent, or any part thereof, remains unpaid for two calendar months after it ought to have been paid, or if default is made in the performance of any covenant or agreement by the lessee and the default continues for two calendar months, the landlord may at any time thereafter re-enter into and upon the demised premises, or any part thereof in the name of the whole, and again have, repossess and enjoy the premises as of his former estate.

Distraint for Rent:

  • Section 30: A landlord may take under a distress for rent any sheaves or cocks of grain, or grain loose, or in the straw, or hay, lying or being in any barn or granary or otherwise upon any part of the land charged with such rent.
  • The remedy of distraint allows a commercial landlord to seize assets belonging to the tenant and sell those assets to recover rent arrears. This remedy is abolished for residential tenancies but remains available for commercial tenancies.
  • It is important to note that distraint and termination of the lease are generally mutually exclusive remedies.

Relief from Forfeiture:

  • Section 14(2): Where a landlord is proceeding by action or otherwise to enforce a right of re-entry or forfeiture, whether for non-payment of rent or for other cause, the tenant may apply to the Court for relief, and the Court may grant such relief as it thinks fit, on such terms as to payment of rent, costs, expenses, damages, compensation, penalty, or otherwise.
  • Section 14(5): Where the action is brought to enforce a right of re-entry or forfeiture for non-payment of rent and the tenant, at any time before judgment, pays into court all the rent in arrear and the costs of the action, the cause of action shall be at an end.

Personal Guarantees and Corporate Tenants

Often, a commercial tenant is a newly formed Limited Liability Corporation (LLC) or a corporation with few physical assets. If the business fails, the corporate veil protects the business owners from personal liability.

To mitigate this risk, commercial landlords in New Brunswick frequently require a Personal Guarantee. This separate legal document forces the owners of the tenant corporation to pledge their personal assets (homes, personal bank accounts) as collateral if the corporation defaults on the commercial lease.

The Offer to Lease

Before the massive final lease is drafted, commercial deals in New Brunswick almost always begin with an "Offer to Lease" or "Letter of Intent" (LOI).

  • The LOI outlines the primary business terms: square footage, base rent, lease term, tenant improvement allowances, and the commencement date.
  • While often considered "non-binding" regarding the final legal language, the LOI typically contains binding clauses regarding confidentiality and a period of exclusive negotiation.
