Escape the Old Post Reviews

  • Great experience! Our game master Michael was helpful (although we didn’t need him too much!) and the challenges were well thought out, and kept us hopping. We finished with minutes to spare and rang the bell! 🔔 It was so much fun working together as a family! It’s definitely worth the trip to Harriston, ON!

    The 6 of us, officially known as ‘The Undecided’, had a great time competing and completing the first stage of ‘Escape The Old Post’, escape room. We had a blast, the game master was very helpful and insightful and helped to keep us on the straight and narrow….. most of the time…. It was quite surprising at how much you had to be a team and rely on each other to finish the clues and move forward. The escape was very well done, maybe not ideal for us 6 footers to get in each room, nonetheless we had a great time and will be back. Thank you Jacob.

    Best escape room i have ever been to. Multiple people can work on different puzzles at the same time, so it's always fast and exciting. The owner was great, and had obviously put alot of work into the room (he had some cool stories as well). We suggest booking back to back sessions, so you have time to complete the whole room (it's a big room). Wherever you are it's worth a drive!

  • Such a great experience! It was so much fun and the attention to detail is incredible. The Game Master is there to support but not give too much away. Really neat to learn the history of the building and the exciting new plans they have for the future.

  • The best escape room experience I've ever done. Also the hardest. Do not expect to finish this on your first visit. It is designed to be completed over several, but it is amazingly complex and enriching. It involves many rooms, hidden compartments and more. The gamemaster will guide you if needed, without providing excessive help. Groups of four or more recommended, we had fun with eight people. Just go.

    One of, if not the best escape rooms we’ve been too! There was so much detail, so many clever puzzles! The room itself was decorated for Halloween which was awesome. Gamemaster Jacob & his team were awesome and made our entire experience even more enjoyable. We will definitely be back! Thank you!

  • What a challenging, fun and well-constructed escape room! 💙 Our group had a great time solving all the riddles and puzzles! 😜 The second half was just as rewarding as the first half that we completed this past June. 🤯 Definitely worth a second visit!!! What a blast! 🥳 Bring your group to Harriston and escape from your daily grind! Thanks Mr. Game Master and Crew.👍

    We had a wonderful time tonight at the escape room in Harriston. Many of us were newbies to escape rooms and our 2 grandmasters made it so much fun. We lived finding all the hidden gems and were very thankful for help in a certain area. Can't wait to go back for part 2!

    I highly recommend Escape The Old Post! Our family had a wonderful time working through the puzzles to ring the bell!! Jacob the gamemaster truly goes above and beyond to make sure you have the best experience possible, which includes cheering you on when you have successfully solved a puzzle, or giving a helpful little hint when you're getting stuck somewhere! 😉 The room is very cleverly designed, and many of the puzzles require team work, which makes it fun for a group! 😊 3 of our group members had completed the room a few years ago, with other friends, and so we had the exciting and fun experience of being co-gamemasters, which meant being able to watch the rest of our family work at the puzzles in the room, and sharing clues when needed. It was the best possible way to be involved with the experience the second time, while not giving away too much info by doing the Escape Room with the newbies! Again, thank you for allowing us to have a fantastic, fun experience, and being so accommodating to our group! For anyone looking for a fun-filled, intense and exciting evening, with family or friends, be sure to check out The Old Post!! 😀😊 you won't be disappointed!!

    This was one of the best, if not the best, escape rooms we’ve done! It is a challenging room, but the game master is helpful and can provide some guidance when needed. The game was full of surprises and neat puzzles. We only did the first part, but will definitely be going back to do part 2 sometime!

  • We thoroughly enjoyed our team building exercise involving 7 Directors and 2 Staff at "Escape the Old Post". It was amazing how each individual collaborated and worked together to solve the various clues and puzzles. It was interesting to see their dynamic leadership skills at work in a fun atmosphere. A great experience!

    I was able to take my grade 7/8 class to the Old Post for a field trip. They were amazing with the students and accomodating with the space both inside and outside for the groups to have lunch and to play game/watch the other groups work their way through the escape room. My students loved the experience and are already planning how to return, even trying to convince myself and their principal we should return this school year. It is a great team building experience that allows for students of all types and abilities to participate and to show their strengths. Students use math, geography, problem solving, reading, writing, team work and other skills to find their way through the puzzles. I would highly recommend giving the Old Post a look for your own class trips.

    Our group of 10 thoroughly enjoyed Escape the Old Post. After an absolutely delicious dinner of pizza, panzerottis, salads and Caesar’s at Harry’s Stone restaurant we walked down the street to the Old Post. We loved the charm of the old building, the history, cleanliness, and the quality of the whole set-up. Sadie, our escape master, was excellent in providing the background and rules of the experience and got us started quickly and efficiently. We worked very well together and started finding clues right away. There was a great variety of puzzles to solve, keys to find, paddle locks to unlock, etc. A lot of thought and creativity went into all the steps in the sequence. Sadie was very helpful in guiding us when we needed it and came up into the attic a few times to assist us. Two improvements that could be made are 1. a louder speaker system (or she could speak louder?) because sometimes we had to get her to repeat her clues and instructions, and 2. more fans or an upright air conditioner as it was a very hot day/night and the smaller and higher rooms were very hot (we were sweating and parched by the end so a water machine or bring your own water would be great!). Sadie compensated by getting us glasses of water from the kitchen and debriefing outside where it was cooler. After a lot of teamwork, thinking, fun and laughs we were successful in completing the first part of the challenge. Yeah!! We plan to return in the fall/winter when it is cooler to try the second part. All 10 participants would highly recommend Sadie and Escape the Old Post as a group activity for a special occasion or just for the heck of it!! Thanks so much for a memorable experience that we will definitely be telling our friends and families about!! It was a great way to celebrate my 56th birthday with lifelong friends!👍♥️🌹

    So much fun! First timers - group of 6 - was for my birthday! The building itself is absolutely beautiful, they have kept so much of the original charm and incorporated allot of it into their escape room. The game master is great, he made the experience fun, gave us some help along the way and gave us a few laughs! Going in as a newbie, we didn’t know what to expect but WOW. So many twists, turns and fun/clever puzzles. We will be back as we haven’t finished part 2, and there is so much more to discover. Highly recommend trying it out! Thank you to the team! What an amazing piece of history you have and with how you’ve done things and restored parts to its original beauty is something to be incredibly proud of!

    What a phenomenal time! Would highly recommend to any group looking for some fun and adventure. Jacob our Game Master was gracious, enthusiastic and well informed on the history of the Old Post building itself. The inquisitiveness, playfulness, organization, and superb construction made it the best Escape Room- bar none; that any one of our group had ever experienced. RUN don't walk to Escape the Old Post!

    My hubby and I host a Cousins Camp each year for our grandkids. This years theme was 'Mission Possible', so of course, we needed to do an Escape Room. The kids came back from Escape the Old Post in Harriston sooooo excited they could hardly get the words out fast enough! They loved, loved, loved it! Jacob was awesome to work with. SO FUN!!! Definitely need to do this again next year!

The Postmaster’s Riddle

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.
