Guy Turcotte, the St. Jerome cardiologist who was found not criminally responsible for the 2009 stabbing deaths of his two young children, will have to face a new double-murder trial.
On Thursday, the Supreme Court of Canada refused to hear his last-ditch appeal which would have averted a new trial.
Turcotte was found to have had mental problems when he killed his two children, five-year-old Olivier and three-year-old Anne-Sophie, by stabbing them repeatedly in February of 2009. He was confined to the Pinel institute before being freed in December 2012.
Last November, the Quebec Court of Appeal overturned the original verdict in the case, and ordered Turcotte be tried again.
No new trial date has been set.
His ex-wife Isabelle Gaston says she hopes her children will finally get the justice they are owed.
But she says the pace of justice has been difficult to deal with.
"The passivity of the system makes me mad," she tells CJAD. "I want to move move on but they are always bringing me back. And financially, I'm a doctor, so when I don't work I don't get money, so that's hard."
She says the murders destroyed her life, and the prospect of another trial is likely to re-open some painful memories she has tried to bury.
