Brockville Psychiatric Hospital: History, Abandonment, and Demolition
If you’re searching for the story behind the Brockville Psychiatric Hospital, you’re looking at one of Ontario’s oldest and most significant mental health institutions, now entering its final phase of demolition and redevelopment.
This site has gone from a 19th century asylum to a partially abandoned complex, and now to an active construction zone that will soon erase most of its historic structures.
The Origins of Brockville Psychiatric Hospital (1894)
The hospital opened in 1894 as the Eastern Hospital for the Insane, part of Ontario’s expanding asylum system.
It was designed using the cottage plan model, which separated patients into multiple smaller buildings instead of housing everyone in a single massive structure. At the time, this was considered a more humane and progressive approach to mental health care.
The property sat on a ridge overlooking the St. Lawrence River, with:
- Patient wards and cottages
- Administrative buildings
- Agricultural land used to support the institution
By the mid 20th century, the hospital had grown into a major regional facility.
Expansion and Peak Years
The hospital saw its largest expansion in the 1950s, increasing capacity and modernizing parts of the campus.
By the early 1970s:
- It employed hundreds of staff
- It was one of the largest employers in Brockville
- It functioned as a self contained mental health community
Like many institutions of its time, it balanced treatment with long term custodial care.
Deinstitutionalization and Decline
Starting in the 1960s, Ontario began shifting away from large psychiatric hospitals.
This process, known as deinstitutionalization, led to:
- Reduced patient populations
- Closure of older buildings
- A move toward community based mental health services
Over time, large sections of the original Brockville Psychiatric Hospital became:
- Vacant
- Underused
- Increasingly deteriorated
However, the site was never fully abandoned.
What Replaced the Original Hospital
While parts of the historic complex fell into disuse, the property remained active with modern facilities, including:
- Brockville Mental Health Centre
- St. Lawrence Valley Correctional and Treatment Centre
This created a unique situation where active medical and correctional services operated alongside abandoned heritage buildings.
Current State: Demolition Has Begun
As of 2025 and into 2026, the remaining abandoned structures are being demolished.
You can no longer consider this a traditional abandoned location:
- Multiple historic buildings have already been removed
- Others are scheduled for demolition
- The site is an active redevelopment zone
For urban explorers and photographers, this means the window to document the original structures has effectively closed.
Future Plans: New Jail and Expanded Treatment Centre
The Province of Ontario is redeveloping the site into a modern correctional and treatment complex.
Plans include:
- A new Brockville jail to replace the aging downtown facility
- Expanded capacity at the St. Lawrence Valley Correctional and Treatment Centre
- New healthcare and support infrastructure
Timeline
- Design phase through 2026
- Construction expected to begin in 2027
Once complete, the site will function as a fully modern correctional and mental health campus, replacing most of the historic hospital buildings.
The End of an Era
For over 130 years, the Brockville Psychiatric Hospital stood as a major part of Ontario’s mental health system.
Today, it represents a full cycle:
- 1890s asylum
- 20th century psychiatric hospital
- Partial abandonment
- 21st century redevelopment
Very little of the original site will remain once construction is complete.
