Commercial late fee provisions in Alberta are subject to far fewer restrictions than residential late fees. There is no dedicated "Commercial Tenancies Act" in Alberta; instead, the relationship is primarily governed by the lease agreement and common law principles of contract. Statutory compliance is guided by the provincial Law of Property Act (RSA 2000, c L-7), the federal Interest Act, and the Civil Enforcement Act.

Key Differences from Residential

Common Late Fee Structures

Commercial leases typically include one or more of the following late payment provisions:

1. Default Interest

  • An annual interest rate charged on overdue amounts from the due date until paid
  • Common rates: 18% to 24% per annum (1.5% to 2% per month)
  • Must comply with the federal Interest Act (rate must be expressed as an annual rate or it is capped at 5%)

2. Flat Late Fee

  • A fixed dollar amount charged for each late payment
  • Example: $250 per late payment or $500 per occurrence
  • Must be clearly stated in the lease

3. Percentage-Based Fee

  • A percentage of the overdue amount
  • Example: 5% of the unpaid rent
  • Applied once per late payment or per month overdue

4. Combination

  • Many leases combine a flat fee with ongoing interest
  • Example: $250 flat fee plus 18% annual interest on the outstanding balance

The Interest Act (Federal)

The federal Interest Act (RSC 1985, c. I-15), specifically Section 4, imposes mandatory requirements on interest-bearing provisions in commercial leases:

Key Requirements

  1. Annual Rate Disclosure — Any interest rate in a contract expressed as a rate for a period less than a year (e.g., monthly or daily) must also contain an express statement of the equivalent annual rate.
  2. The 5% Legal Cap — If the annual rate is not explicitly disclosed, the recoverable interest is legally capped at 5% per annum, regardless of the rate specified in the lease.

How to Comply

  • Always state the interest rate as an annual rate: "18% per annum, calculated and compounded monthly"
  • Include both the monthly and annual rates if using a monthly calculation
  • Have a lawyer review all interest-bearing provisions for Interest Act compliance

Grace Periods

There is no statutory grace period for commercial rent payments. Rent is due on the date specified in the lease. However:

  • Many leases include a 3–5 business day grace period before late fees apply
  • Some leases impose fees immediately upon the due date with no grace period
  • The grace period (or lack thereof) should be clearly stated in the lease

NSF (Non-Sufficient Funds) Charges

When a tenant's payment is returned for insufficient funds:

  • The lease should specify an NSF fee (commonly $50–$250 per occurrence)
  • The landlord may also charge for any bank fees incurred
  • After multiple NSF incidents, the landlord may require the tenant to pay by certified cheque, wire transfer, or e-transfer only

Acceleration Clauses

Some commercial leases include an acceleration clause that makes all remaining rent for the lease term immediately due and payable upon default:

  • Triggered by non-payment or other material defaults
  • Requires clear and specific lease language
  • Courts have generally upheld acceleration clauses in commercial leases if clearly drafted
  • May be subject to a mitigation obligation (landlord must try to re-let the space)

Enforcement Strategies

Step 1: Demand Letter

  • Send a formal written demand specifying the amounts owed, applicable late fees, and a deadline for payment
  • Delivered by registered mail or personal service

Step 2: Apply Late Fees

  • Calculate and apply all late fees and interest as per the lease
  • Provide a clear statement of account to the tenant

Step 3: Exercise Lease Remedies

  • Termination — End the lease and retake possession according to the lease terms
  • Civil Action — Sue for the outstanding arrears and prospective rent
  • Refer to the Commercial Eviction Process for details

Step 4: Legal Action

  • Sue for unpaid rent, late fees, interest, and damages
  • Claim against personal guarantees if applicable
  • Seek a court judgment and enforce through the Civil Enforcement Act (RSA 2000, c C-15)
  • Note on Distress: Under Section 45 of the Civil Enforcement Act, landlords are strictly prohibited from seizing a tenant's goods themselves. All distress actions must be conducted by a licensed civil enforcement agency.

Unconscionability

While commercial late fee provisions have broad latitude, courts may still refuse to enforce terms that are unconscionable:

  • Excessively high interest rates combined with multiple penalty provisions
  • Late fee structures that generate more revenue than the underlying rent
  • Terms that were not properly disclosed or negotiated
  • Situations where one party had significantly more bargaining power

Best Practices for Landlords

  1. Express interest as an annual rate — Comply with Section 4 of the federal Interest Act to avoid the 5% cap
  2. Include a reasonable grace period — 3–5 business days is standard
  3. Set competitive default interest rates — 18% per annum is common and generally enforceable
  4. Include NSF provisions — Specify fees and the right to require alternate payment methods
  5. Draft clear acceleration clauses — If included, ensure they are specific and enforceable
  6. Maintain detailed payment records — Track all payments, late fees, and interest accrued
  7. Act consistently — Apply late fee policies uniformly across all tenants
  8. Communicate promptly — Notify tenants immediately when payments are late
  9. Consult legal counsel — Have late fee provisions reviewed for Interest Act and Law of Property Act compliance
