Ontario's Health Minister David Caplan went about his daily duties on Monday, brushing off questions about what responsibility he should take for the spending scandal surrounding eHealth Ontario, the provincial electronic medical records agency.

"Well, I take the responsibility to ensure that Ontarians are well-served, to make sure that first of all we get to the bottom of whatever the matter is, which is why I took quick action," he told reporters in Hamilton on Monday.

Caplan was at McMaster hospital to help open a new unit.

Earlier on Monday, opposition parties renewed their call for his resignation following the removal of a top executive at the provincial agency over the weekend.

CEO Sarah Kramer stepped down from her post on Sunday after the agency's board determined that a change in leadership was essential in order to move its mandate forward.

The agency was created last fall with the task of creating an electronic database of the health records of all Ontarians. It cost taxpayers $650 million but the agency has produced very little of value so far.

In the past several weeks the agency has been plagued with accusations of mismanagement and mispending after it was revealed that $5 million worth of contracts were awarded to friends and Liberal party supporters without going out to tender.

Kramer came under fire for taking a $114,000 bonus on top of her $380,000 salary even though she had just been on the job for three months.

She will receive 10 months salary -- $317,000 -- in severance pay, even though her contract called for 15 months of severance pay.

NDP Health Critic France Gelinas said the health minister should resign from his post in order to restore public trust in eHealth Ontario.

"You have to realize he built it with no accountability built in, no fiscal accountability," she said. "Only in the Liberal world is this the cost of doing business. For the rest of Ontario this is not acceptable. This minister has to go."

Elizabeth Witmer, the Progressive Conservative health critic, echoed that call. "I definitely believe the minister should resign ... ultimately as a minister, you are accountable," she said.

However, Caplan told The Canadian Press that he is not stepping down.

He said he's asked Ontario's auditor general to speed up his review of the agency's operations.
