Ontario is being urged to end its standoff with Ottawa over health care funding.

Mental health advocates say Ontario and other holdout provinces -- such as B-C and Quebec -- need the money now to make sure needy patients have access to critical front-line services.

The Mental Health Commission of Canada's president Louise Bradley says other provinces -- most recently Saskatchewan -- have identified mental health as a funding priority, and signed bilateral deals with the federal government.

Ontario Finance Minister Charles Sousa says Ottawa has been acting unilaterally, while the provinces want a chance to negotiate.
