OTTAWA - Federal Health Minister Leona Aglukkaq is welcoming the country's first national mental health strategy.

But it's not clear whether Ottawa will take a minor or major role in its implementation.

The minister's presence at the formal launch of the Mental Health Commission of Canada's blueprint suggests government will be a player of some kind.

But Prime Minister Stephen Harper has often suggested that health-care delivery is best left to the provinces.

And the minister has made no mention of federal money for the strategy.

She has invited the head of the commission to attend an international conference on mental health with her.
