The Old Post has seen its share of renovations in the last couple of years, and no area more so than the attic.

For more than a century, this magical space was only accessed by an old wooden ladder through a small hatched opening in the second storey ceiling. The potential of this mostly forgotten floor was begging to be explored.

Once restoration of the first and second floors were complete in early 2016, interest inevitably turned upward to the mysterious and completely untouched third floor. With unique characteristics such as a clock tower, a 1,200 pound bell, the small “archer’s” room with six slender windows, and the massive central skylight structure, the design possibilities were extraordinarily interesting to say the least.

But what to do…

It was obvious from our research that the McCready family was going to play a very prominent role in the history of The Old Post. Alexander McCready was appointed Postmaster of Harriston in 1859.

He was a respected citizen of the town, but was also remembered as somewhat of an enigma, being a bit eccentric and known to be a master storyteller. Holding the position for 45 years, he handed over the title to his eldest son Robert in 1905.



Sadly, Alexander died in 1908, just a few years before the construction of the Old Post began in 1912. His long-desired dream of gazing up at the four storey clock tower and hearing the ringing of the bell was not meant to be.

Robert McCready was Postmaster until 1939 when he, in turn, handed over the reins to his only son, Archibald. This was the first time a third generation appointment had ever been made. Archibald was Postmaster until he retired in 1970.

Now, how does all this relate to what’s been happening on the third floor?

Well, even though old Alexander McCready died prior to construction of the Old Post, his influence has very much been felt.

Amid the cleanup of the third floor, some documents were discovered hidden in an old crate.

Two of the articles within these documents became immediately noteworthy.


The first was a rudimentary sketch of the third floor dated 1914, diagramming possible design features and concepts, and covered in extensive notes and descriptions.

The second article was a lyrical poem or “riddle” written by none other than old Mr. Alexander McCready. It was instantly clear that the two articles were related and that somebody, predictably Robert McCready, envisioned the construction of a fairly peculiar endeavour on the third floor of The Old Post based on his late father’s riddle.


Why the plan never became a reality is a mystery.

Perhaps the fact that the country would soon join the First World War has something to do with it.

After being hidden away for more than a century, the combined vision of Alexander and Robert McCready has come to fruition.
