A credit rating is a current assessment of the creditworthiness of a borrower with respect to a specified obligation. It indicates the capacity and willingness of a borrower to pay interest and principal in a timely manner.
The Province of Ontario's current ratings are as follows:
| Long-term | Short-term | |
| Standard & Poor's | AA- (N) | A-1+ |
| Moody's Investors Service | Aa2 | P-1 |
| DBRS | AA (low) | R-1 (mid) |
Long-term Ratings are also assigned an outlook indicating the likely direction of an issuer's rating over the intermediate term, typically ranging from 6 months to 2 years. The outlook is denoted (P) for Positive Outlook, (N) for Negative Outlook or (D) for Developing Outlook. No identifier is attached to the rating if the outlook is Stable.
Short-term Ratings are for debt maturities of less than one year. Ratings are graded into several categories, ranging from the highest-quality obligations to default.
