The Abandoned Brookside Youth Detention Centre in Cobourg is one of those places that carries a lot more weight than your typical abandoned property. What sits empty today was once part of Ontario’s youth correctional system for decades, and walking the grounds, you can still feel that history in the layout and the buildings themselves.

I explored this location during the summer of 2025 alongside Zenning with Zay, with some helpful intel from Freaktography that pointed us in the right direction. It’s a large site, and without that kind of insight, it would be easy to miss key areas or overlook how much is actually still standing.

The property dates back to the 1930s, originally operating as a training school for girls before transitioning into a boys’ facility in 1948. Over time, it evolved into a secure custody centre for young offenders, eventually becoming what most people knew as Brookside Youth Centre. At its peak, it functioned more like a small campus, with multiple buildings spread out across the property, including residences, administrative spaces, and schooling areas.

By the time it closed in February 2021, the facility was only housing a small number of youth. Rising operational costs and a shift toward community-based programs led to its shutdown. Since then, the site has sat empty, with redevelopment plans slowly making their way through discussions and proposals.

Today, you’ll find a mix of structures in varying condition. Some areas are heavily deteriorated, while others still feel relatively intact, almost like they were left behind in a hurry. The scale of the property is what really stands out—it doesn’t feel like a single building, but more like a contained institutional environment.

There’s also a heavier side to this location that can’t be ignored. Former residents have come forward over the years with allegations of abuse tied to facilities like this one, adding another layer to how the site is viewed today. It’s not just an abandoned complex—it represents a system that has since been reevaluated and, in many ways, changed.

Walking through in the summer heat, it was quiet—almost too quiet for a place that once held so much activity. The layout, the fencing, the separation between buildings—it all reinforces what the space was designed for. Even without anything happening there now, it still feels controlled and structured in a way that hasn’t fully faded.

The future of the property is still uncertain, though it has reportedly been sold and is expected to be redeveloped. Whether that means housing, community use, or something else entirely remains to be seen.

For now, the Abandoned Brookside Youth Detention Centre remains a snapshot of a system that has largely moved on—left behind, but not forgotten.
