EDMONTON -- An agency is maintaining Alberta's credit rating but says the outlook for the long-term is negative because of the government's unwillingness to deal with its deficit and growing debt.

DBRS Limited says the rating remains at AA-high, but the trend on long-term ratings has been changed to negative from stable and the province could face a downgrade within a year.

The agency says Alberta's economy is improving and appears to have turned a corner supported by a modest rise in oil prices.

However, it also says the government's new budget fails to demonstrate meaningful action to address a substantial budgetary gap.

The government had a $10.8 billion deficit last year and is forecasting a $10.3 billion deficit this fiscal year.

Finance Minister Joe Ceci says by maintaining the credit rating, DBRS is recognizing Alberta's strong fiscal fundamentals.
