Ken Masse's childhood house is the last obstacle standing in the way of a multibillion-dollar mining project in the town of Malartic.

A Superior Court judge awarded Osisko Mining Corp. possession of Masse's home after the company requested an emergency court decision.

In a ruling presented Tuesday, Judge Robert Dufresne wrote that Masse's house is preventing key preparation work for the mining project from moving forward.

Masse had been scheduled to appear in court next month to fight a government expropriation order. He has been representing his mother, Mary Elizabeth Wilczynski, who owns the home.
