A centuries-old tradition is returning to Toronto’s west end this month, and while you might see smoke rising from the treeline, there’s no need to call 911.
For over two decades, the City of Toronto has conducted annual Traditional and Prescribed Burns in High Park and Lambton Park. This spring ritual involves a carefully choreographed “cleansing fire” designed to protect some of Ontario’s rarest ecosystems.

The upcoming burns aren’t just about maintenance; they are a vital lifeline for the rare Black Oak Savannahs found in High Park and Lambton Park. These sun-drenched woodlands are home to unique prairie plants that actually crave the heat.
High Park is home to nearly 30 hectares of fragmented savannah, making it the most significant site of its kind in the city. Lambton Park is another key location where fire helps native species outpace invasive ones.
The Spirit Of The Burn
This year, the event continues its deep collaboration with the Indigenous Land Stewardship Circle. Known in Anishinaabemowin as Biinaakzigewok Anishnaabeg, the practice honours the traditional practice of Indigenous people on Turtle Island
Watch from a distance as a highly trained Fire Boss and their crew lead a low-intensity flame across the forest floor. The fire moves at a walking pace, consuming only dried leaves, twigs, and grass stems while leaving the majestic, thick-barked Oaks completely unharmed.

What You Need To Know
Because the burn requires very specific wind and moisture levels, the exact date is kept under wraps until 24 to 48 hours before ignition. However, the city is currently eyeing dates in April.
Keep in mind that High Park will be closed to vehicles on the day of the burn. Certain trails and sections of Lambton Park will also be cordoned off to keep everyone – including your four-legged friends – safe.
While the smoke is expected to rise and dissipate quickly, those with respiratory sensitivities or allergies to poison ivy are encouraged to keep their windows closed or spend the afternoon in a different part of the city.
Once the smoke clears, the result is a burst of new life, as the nutrient-rich ash helps Toronto’s native wildflowers and grasses grow back greener and stronger than ever before.
