Solar Power Update: SCC Leave to Appeal Refused


In January 2018 the Ontario Superior Court of Justice released a decision, Solar Power Network Inc. v. ClearFlow Energy1, which raised concern for lenders regarding interest payable by borrowers that is not expressed on an annualized basis. This decision was reversed in part by the Ontario Court of Appeal (ONCA).2 A summary of this decision can be read here.

On March 28, 2019, the Supreme Court of Canada refused the leave to appeal application resulting in far greater certainty for lenders in respect loan agreements and interest payable by borrowers thereunder.

As outlined in our e-LERT published in September 2019, the three takeaways of the ONCA decisions that lenders should be aware of are as follows:


  • Section 4 of the Interest Act3 will be satisfied when an annualizing formula is included in the loan agreement.
  • If the agreement is a commercial loan agreement consistent with modern commercial reality it may not need to provide an annualizing formula to comply with Section 4 of the Interest Act.
  • Always provide an annualized rate when there is no formula. Even though the Court took a commercial reality test into account, it still held that if interest were set out only on a monthly basis, it needed to be annualized. Section 4 of the Interest Act will not be satisfied if the agreement, for example, provides for interest at 2% per month calculated monthly but which is payable on the due date of the loan or promissory note. In such a scenario an annualized rate must be provided to comply with Section 4. This is likely one of the most common mistakes made by non-Canadian lenders.
