Unimaginably grand Toronto mansion with secret tunnel hits the market for $23M

If your idea of a Toronto "starter home" includes a ballroom, a secret tunnel, and space for 300 of your closest friends… 52 Post Rd. might just be your vibe.

Tucked into the ultra-exclusive Bridle Path — aka the city's most unapologetically over-the-top pocket of wealth — this French Neoclassical mega-mansion is less "house" and more "private palace."

Built in 1990 by George and Judy Frankfort, the estate was designed with one very specific goal: high-scale entertaining and opulent galas to support their philanthropic pursuits.

The Grand Salon.

Mission very much accomplished.

The primary bedroom. 

The result? More than 25,000 square feet of living space, seven bedrooms, 12 bathrooms, four stairwells, and not one but four kitchens.

The foyer. 

From the moment you pass through the gates, the home leans hard into Versailles -like energy.

A sitting room. 

Now, sure — the interiors won't be everyone's taste, but they are undeniably opulent. 

The massive primary ensuite. 

We're talking grand arched doorways, intricately patterned marble floors, ornate wrought-iron railings, and proportions so massive that even the hallways feel like they're waiting for a guest list.

The entrance into the Grand Salon. 

And then there's the main event.

A view from above. 

The Grand Salon, set right at the heart of the home, is a two-storey, 23-foot-high showpiece that can host up to 300 guests. It's the kind of space that practically demands a string quartet and a champagne tower.

The space is meant to hold up to 300 people. 

"It provides an exquisite setting for large family gatherings and the refined philanthropic pursuits of luxury connoisseurs," said realtor Jane Zhang.

Elsewhere, the drama doesn't let up.

The spiral staircase lit up with a three-storey wall of windows. 

A striking three-storey wall of windows in the north wing floods the space with natural light, while sweeping circular staircases add just the right amount of theatrical flair.

The spa room. 

Downstairs, things shift into full-on luxury resort territory.

The wine cellar. 

There's a wellness spa, sauna, hot tub, gym, wine cellar, and a sprawling billiards room.

The lower level.  

There's even a secondary dining hall and kitchen because apparently one entertaining zone simply isn't enough.

The coach house. 

And then there's the tunnel. Yes, an actual underground tunnel connects the main house to a separate coachhouse, complete with a self-contained apartment and a five-car garage. Walking outside? Optional.

The tennis court and children's playground. 

Out back, the property doubles down on the whole private-club fantasy: a tennis court, a pool with a diving section, a pool house, a children's playground, and expansive manicured grounds lined with mature trees and winding pathways.

The main kitchen. 

Basically, it's the kind of place where you could host a gala, a wedding, and a weekend getaway… all at the same time.

The back of the house and the pool. 

If you're wondering what all this grandeur will cost you, 52 Post Rd. is currently listed for $22,980,000.
