Inside Canada’s largest mansion — abandoned for more than 15 years and left to rot

Once envisioned as a luxurious lakeside palace, Canada’s largest home now sits abandoned, with broken windows and unfinished floors serving as eerie reminders of what could have been.

The Peter Grant mansion, sprawling across 65,000 square feet on the shores of Lake Temiskaming in Ontario, has been left to rot for more than 15 years.

The once-grand estate was the brainchild of Peter Grant, the former president of Grant Forest Products, who dreamed of creating an opulent retreat.

The plans included over-the-top features like a subterranean boathouse, an art gallery and even a private golf course.

Grant’s company filed for bankruptcy protection in 2009, leaving the colossal structure an empty shell, with half-finished walls and floors that never saw actual use.

Despite its abandoned state, the mansion has gained fame as Canada’s largest residence.

But aside from its sheer size, what’s inside the mansion now is far from a dream.

Instead, scattered construction debris and graffiti tell the story of a project left in ruins.

The massive home was listed for a jaw-dropping $25 million, even though it’s far from livable.

A Toronto-based company eventually bought the estate, but in 2023, it was reported that very little had changed beyond some security upgrades.

In an effort to stop curious onlookers from exploring the crumbling mansion, security cameras and fences were installed.
