Historic Ontario post office turned 12-unit apartment building hits market for $3.5M

It's not often you can own a piece of Ontario heritage, but a massive slice of history just hit the market this week, and it could be yours for a few million bucks. 

In downtown Georgetown, the properties at 70 Mill St. and 72-74 Mill St. are being sold together as an assembly.

Between them, you're looking at nearly half an acre of prime real estate in the heart of Georgetown, complete with heritage status, historic architecture, and even a few tales of mail carriers and movie-goers from yesteryear.

Designed in an Art Deco style by architects J.E. Walker and J.G. Elliott, 70 Mill St. was built in 1935 with limestone from nearby Glen Williams and bricks and lime from Milton.

It was built by J.B. Mackenzie and S.J. Mackenzie, and at the time, the construction only cost a whopping $42,000 (which, let's face it, wouldn't even cover the deposit today).

Original hardwood floors, doors and trim add to the charm of the building. 

The structure was officially opened as the Georgetown Post Office and Customs House on February 1, 1936, after the town spent nearly a century petitioning for better mail service.

But by the early 1960s, the building had become too small for the growing postal demands, and the operations were eventually moved.

Since then, 70 Mill St. has transformed into a 12-unit residential building with its own green space and surface parking — while still proudly holding its heritage-listed status (as of 2007).

72-74 Mill St. 

Next door, 72-74 Mill St. carries its own story — once home to the Roxy Theatre, it's now a mixed-use building with eight commercial offices and four residential units.

And while the lights of the old movie house have long gone out, the potential here is anything but dim.

Combined, these two addresses represent a rare redevelopment opportunity in the heart of a downtown core that's already buzzing with growth.

For context, Georgetown property values have gone up over 125 per cent since 2015, and Halton is one of the fastest-growing regions in Ontario.

Also, it wouldn't be the first historical property to get a modern makeover. 

The nearby McGibbon on Main development — a 10-storey residential complex that pays homage to the beloved McGibbon Hotel — is just one example of how heritage and modern living are coexisting beautifully in Halton Hills.

Whether you're a history buff, a developer with vision, or just someone who has always wanted to own a post office (hey, we don't judge), 70-74 Mill St. offers a mix of investment potential, character, and location.

It's steps from boutique shops, the local library, the seasonal Farmer's Market, and GO Bus connections to Toronto. Plus, public parking makes life easier for tenants and visitors alike.

70 Mill St. is listed for $3,500,000 and 72-74 Mill St. are listed for $2,400,000.
