Collateral mortgage

A collateral mortgage, or collateral charge, lets a lender secure several loans against the same property, and the Financial Consumer Agency of Canada says the lender may register a charge higher than the mortgage amount. It differs from a standard charge, which secures only the mortgage.

A buyer may meet this term if a lender asks for security over land or a building, whether it is bought with the business or owned by the buyer or a guarantor. The FCAC describes the charge in consumer-mortgage terms, so ask a business lender how its own charge is written.

Standard versus collateral

The FCAC says a standard charge only secures the mortgage, while a collateral charge mortgage may secure multiple loans with the lender. The CSBFP guidelines from ISED also use the term: they say that in some jurisdictions the only way a lender can secure a mortgage from an individual is a personal guarantee secured with a collateral mortgage on the property for the same amount, documented as taken only to secure an asset of the small business.

What to check or ask

  • Which loans the charge secures now, and which future debts it could secure.
  • How the registered amount compares with the loan.
  • How the charge is released when the loan is repaid. See discharge of security.
  • How land registration and mortgage rules work in the province where the property is.
