Toronto's High Park cherry-blossom trees are expected to reach their peak bloom by the end of April or early May 2024 [3].
The annual bloom attracts thousands of visitors to the city, creating a significant seasonal surge in tourism and local foot traffic. Precise timing is critical for visitors and city planners managing the influx of crowds.
Steven Joniak, a Toronto resident known online as “Sakura Steve,” has monitored the growth of the trees for more than a decade. Joniak tracks the blossoms each spring to share timing updates with the public, based on his long-term observations of the park's canopy.
High Park contains roughly 3,000 cherry-blossom trees [1]. While the Toronto Star reported peak bloom would occur in early May, other reports suggest the window opens at the end of April [3].
The blossoms are not limited to High Park. Kariya Park in Mississauga, a Japanese-style garden, hosts about 80 cherry-blossom trees [2].
Joniak said he is passionate about the annual display. His monitoring helps the community anticipate the brief window when the blossoms are most vibrant, a period that varies slightly each year depending on temperature and weather patterns.

The reliance on citizen scientists like Steven Joniak highlights a gap in official municipal tracking for botanical events. By combining anecdotal evidence from long-term observers with official park data, the city can better predict peak tourism windows, which is essential for managing infrastructure and environmental protection in High Park.
