Hidden Treasures: Exploring Ontario’s Underground Cities and Structures

Ontario, Canada, offers a variety of unique and lesser-known underground sites that represent significant historical and architectural achievements. While The PATH in downtown Toronto and the Toronto subway system are well-documented, there are also many hidden structures not typically accessible to the general public. This article explores some of these intriguing underground cities and structures, providing insights and practical advice for those who are interested in urban exploration.

Discovering the Underground:

Ontario's rich mining history and diverse landscape have led to the creation of numerous underground cities and structures. In contrast to the mythical lost city of Atlantis, these are actually hidden structures that remain largely unknown to the public. For example, while The PATH in Toronto is a vast network of pedestrian walkways connecting various buildings, transit stations, and shopping areas, it is not always recognized as a part of the underground city framework. Same goes for the historical Toronto Subway System, which, though integral to the city's infrastructure, often goes unnoticed by visitors.

The Underground City of Montreal:

While not located in Ontario, the Underground City of Montreal is worth mentioning. Known as the RESO, this bustling network of tunnels, shopping centers, hotels, and metro stations is a testament to urban ingenuity. Although not in Ontario, it serves as a prime example of how underground cities can be interconnected and vibrant.

Old Mine Sites and Historical Forts:

Ontario has a rich mining history, particularly in regions such as Sudbury and Cobalt, where some old mines have been abandoned. These sites, while not typically referred to as cities, offer glimpses into the area's industrial past. Similarly, historical forts and tunnels like Fort Henry in Kingston, which were used for defense and storage, add another layer of intrigue to the region's underground spaces.

Adventures in Urban Exploration:

A curious and adventurous foster kid growing up in Toronto, I joined other like-minded explorers for a series of urban adventures. Our explorations ranged from subway tunnels to sewer systems and abandoned industrial buildings. We even accessed the machine rooms of several skyscrapers using elevator tops and shafts. While such endeavors can be thrilling, they are also highly dangerous and not recommended. What we did was undoubtedly stupid, but we were cautious to avoid critical infrastructure like trains or large machinery.

Natural Exploration:

For those who prefer safer and completely legal exploration, natural spaces like caves and ravines offer a more accessible and exciting alternative. Toronto's vast green spaces and parklands provide numerous opportunities for adventure. One of my favorite places to explore was down the path between the Sunnybrook park horse stables and the hill up to Sunnybrook hospital. This area features an old bridge and tunnel that leads into a ravine, hidden from public view. Making sure to bring a cellphone, first aid kit, and letting someone know your plans are essential for safe exploration.

Conclusion:

While Ontario may not have cities like Atlantis, it certainly has its share of hidden structures and underground cities that are worth discovering. Whether it's through historical landmarks or natural spaces, there are countless worlds to explore within the city limits. Just remember to prioritize safety over adventure and legal compliance over thrill-seeking.
