DBRS Morningstar Confirms Ratings of Toronto Hydro Corporation With Stable Trends

Utilities & Independent Power
April 28, 2023

DBRS Limited (DBRS Morningstar) confirmed the Issuer Rating and Senior Unsecured Debentures & MTNs rating of Toronto Hydro Corporation (Toronto Hydro or the Company) at "A," and the Commercial Paper rating at R-1 (low). All trends are Stable. The ratings of Toronto Hydro are based on the Company's stable regulated electricity distribution business, which operates under a reasonable regulatory environment under the Ontario Energy Board.

There have been no material changes to Toronto Hydro's business risk assessment since the last rating confirmations. The Company continues to operate under the Custom Incentive Rate-setting framework as approved for 2020 to 2024. DBRS Morningstar notes Toronto Hydro has begun preparation work for its next distribution rates application for the 2025 to 2029 period. DBRS Morningstar will monitor progress on the application for any implications on the Company's credit profile.

Toronto Hydro's financial risk assessment has been supportive of the "A" ratings, with all key credit metrics in line with the current rating category. DBRS Morningstar notes, however, the Company's metrics weakened in 2022 because of the significant capital expenditures (capex) program (gross capex of $675 million for the year) to maintain safety and reliability, support a growing city, enable clean energy, and prepare for and respond to extreme weather. Toronto Hydro's financial ratios may continue to weaken over the next few years as the ongoing capex program will likely require substantial debt financing. DBRS Morningstar expects the Company to be prudent in managing its debt load in order to maintain leverage in line with the regulatory capital structure of 60% debt. However, should the Company's key credit metrics weaken to a level no longer commensurate with the "A" rating category for a sustained period of time (cash flow-to-debt less than 12.5%, debt-to-capital more than 65.0%, and EBIT-interest coverage less than 1.80 times), a negative rating action may occur. Conversely, a positive rating action is considered unlikely at this time given the capex program in place and the current business risk assessment.
