Newfoundland funds 50 scans per year or 10 scans per 100,000 residents per year.

In contrast with the rest of Canada, Ontario had a philosophy that resulted in limiting PET scans for cancer patients. Many viewed this as disadvantageous to the patients, as well as to further medical development, and have voiced their concerns for greater access to PET scanning in Ontario.

However there is also a contrary view. While PET scans are important and useful if used by the right patients, new research has found that the public may be being misled by marketing of medical scans. Private clinics selling high-tech services to screen healthy people for disease could be harming Canadians with the potential for false positives, and excess radiation. It could also place an undue burden on the public health system by diverting resources from the lower-cost and arguably more important work diagnosing and treating disease, and lead to greater investigations from an increasing rate of false positives. Many consumers are inadequately informed about the benefits and harms related to screening technology, including PET scans. With information to help the public understand how health information and studies are generated, as well as some common mistakes and misconceptions, they can make better informed decisions about the use of new technologies like PET scans.
