In an attempt to address the problem, the Canadian government has started offering a $1,500 reward for anyone who can identify the “white bedroom” in the home.
The reward has now been raised to $2,000.
The home has been listed on the real estate site Redfin and is for sale in Victoria, British Columbia.
The home was built in 1928 and has a three-bedroom unit that sits on a 4.2-acre lot.
The house is located in the town of Westlock, which is near Vancouver.
“It’s an extraordinary place,” owner Tom Richey told the CBC.
“You’re not even in the neighborhood, but it’s got so many history.”
