Bret McCann, son of Lyle and Marie, made a statement on Canada’s Criminal Code alongside conservative MP Michael Cooper of St. Albert-Edmonton in St. Albert Sunday.

On September 15, Justice Denny Thomas convicted Travis Vader with two counts of second-degree murder for allegedly killing the McCanns, citing Section 230 of the Criminal Code – a section that was declared unconstitutional by the Supreme Court of Canada in 1990.

“If ever there was a case in which a serious miscarriage of justice occurred as a result of the application of an inoperative section of the criminal code, it is what has happened to the McCann family,” Cooper said.

Vader’s conviction was downgraded to manslaughter on October 31 due to the use of the unconstitutional section.

“The consternation and pain endured by my family because of this so-called zombie law was enormous,” McCann said. "What the minister needs to do is stop picking and choosing which unconstitutional sections of the Criminal Code to remove, and demonstrate leadership by introducing a comprehensive piece of legislation to see all sections that are clearly inoperative and clearly unconstitutional removed."

His parents, both in their late 70s, disappeared on their way to a family camping trip in British Columbia in July 2010.

Their bodies have not been found, but their burned-out motorhome and SUV were found weeks after their disappearance.

The last six and half years have been a “rollercoaster” for Bret and his family, but they will not give up in their pursuit for justice.

 “I really hope to see something positive come out of this. I'd like to see something positive like this result from my parents' tragedy," McCann said.
