Help solve a mystery: Who's behind Montreal's pink house?

On paper, the old Malting site in Montreal's Saint-Henri neighbourhood has been abandoned since 1985.

Yet someone or a group of peopleseems to have taken up residence inside the old industrial buildings.

Last October, the cabin on top of the Malting was mysteriously painted a bright shade of pink. Colourful shutters and window boxes were added. Christmas lights too.

But who did it? And why? Are they living there?

What's going on?

"It's been like it's a source of intense mystery," said Toula Drimonis, a columnist and Saint-Henri resident.

"Everyone keeps asking each other if anyone knows anything.... There seems to be a lot of secrecy."

"It's like, so Montreal, because there's no rhyme or reason to it."

Montreal police say there is no active investigation into who painted the house, but in a statement said the area is patrolled to prevent people from climbing into the Malting.

Why is the Malting abandoned?

The Malting plant and elevators were built in 1905 by the Canada Malting Co. Large cement silos were added in the 1940s to store the barley.

The company exported the malt along the Lachine Canal, and when the canal closed to commercial navigation in 1970, the transportation cost rose to the point that the company abandoned the site in 1980.

Since then, it's fallen into disrepair. Windows are boarded up, brick walls are crumbling, and the facade is covered in graffiti.

The Malting, as it's known locally, is an enduring symbol of Saint-Henri's industrial past.

"People need to understand:this building is such an integral part of this neighbourhood,
said Drimonis.

"As someone who's lived here for ten years, I can't imagine Saint-Henri without it."

Trespassing is illegal and dangerous, but a quick search of Instagram shows that it's a popular destination for "urban hikers" looking for thrills and adventure.

The plant cost $350,000 to build 115 years ago. The land and buildings are now estimated to be worth about $1.9 million. Municipal records show it is owned by Quonta Holdings Ltd., a Montreal-based company. The company did not respond to a request for comment.

In recent months, two groups have put forward proposals to re-develop the Malting.
