Hotel-Dieu Grace Hospital in Windsor, Ont., apparently caught four of the errors attributed to pathologist Dr. Olive Williams before any harm was done, but two patients were not so lucky, according to an internal report by regional health officials.

The fifth patient underwent an unnecessary colostomy due to an incorrect cancer diagnosis, while the sixth patient received an incorrect lumpectomy, it said.

“The error has been attributed to some extent to a physical issue with the pathologist — that is presence of cataracts,” the report states.

Williams, whose hospital privileges were suspended in January, had been on staff since 2004 and also did work for other hospitals in the area. She couldn’t be reached for comment Monday.

The report from February also suggests the hospital was unwilling to reveal what it found were the errors made by Williams to the public until it knew the “full scope” of the problem.

“The hospital would like to review sample charts before going public in order to determine the magnitude of this issue and not alarm the public,” the report states.

The Erie St. Clair local health integration unit (LHIN), which oversees hospitals in the Windsor area, put out the report after it was released through freedom of information laws.

The document was dated Feb. 16, the same day a local Windsor television station was planning to air a story about Windsor surgeon Dr. Barbara Heartwell performing an unnecessary mastectomy on a patient.

The DHC-2 Beaver float plane crashed around 11 a.m. Saturday in a swamp two kilometres from the La Grande Riviere airport, not far from James Bay.

The pilot and one passenger died and all three surviving passengers were flown to a hospital in Montreal, two of them with serious injuries.

Quebec provincial police and TSB investigators were on the scene Sunday, examining whether pilot error or a mechanical problem caused the plane to crash shortly after takeoff. They were also planning to pull the wreckage out of the water.

The pilot worked for Nordair, a commercial and corporate airline that operates in the James Bay and Hudson Bay area.

Quebec provincial police spokesman Richard Gagne said at least two of the passengers were from Ontario.

Investigators determined Sunday the float plane had taken longer than usual to take off, before crashing soon after taking flight, said Transportation Safety Board spokesman John Cottreau.

The weather in the region was clear at the time of the crash.

But before Capt. Robert Semrau learns his fate, a military judge will decide whether sentencing provisions of the National Defence Act violate the Charter of Rights and Freedoms.

During Semrau’s trial, his lawyer argued that because punishments in the Act aren’t the same as in the Criminal Code, they would violate his client’s rights.

A decision on the issue was put off until the five-member military panel hearing the case had reached its final judgment.

One week ago, the panel found Semrau guilty of disgraceful conduct for shooting an Afghan fighter after of a heated battled in the Helmand district of Afghanistan in October 2008.

Semrau could serve up to five years in jail or be dismissed from the military.
