SASKATOON - The man who headed up a Royal commission on health care in Canada says the system needs some work, but changes should not include privatization.

Former Saskatchewan Premier Roy Romanow says there's no evidence that "grafting" elements of privatization onto a public health care system works.

The comment comes as Canada's doctors gather for their annual meeting and look at a new "blueprint" for health care.

Doctor Robert Ouellet, the president of the Canadian Medical Association, has said that he believes there could be a role for private health-care delivery within the public system.

Romanow says he's not being critical of the doctors, but he feels that the same arguments are being made in an old debate.

He also notes that past suggestions to improve the system, including nearly 50 recommendations in his own 2002 report, were never fully implemented.
