Historical Climate Events
Major flooding occurred in the Hunter region, impacting Toronto and surrounding areas. Heavy rainfall caused creeks and Lake Macquarie to overflow, inundating homes and businesses.
SourceBushfires in the region caused smoky conditions and some property damage in areas near Toronto. Firefighters battled blazes in nearby bushland.
SourceA severe storm brought heavy rain and strong winds to Toronto, causing power outages and some property damage. Trees were uprooted and flash flooding occurred in low-lying areas.
SourceToronto experienced a prolonged heatwave with temperatures exceeding 40 degrees Celsius for several days. This put strain on the electricity grid and caused health concerns for vulnerable residents.

Learn moreAbout Toronto's Climate Risk Profile
Toronto, situated on the western shore of Lake Macquarie in New South Wales, is a suburb that will experience notable impacts from climate change. The primary concerns for Toronto are increased flooding due to more intense rainfall and rising lake levels, more frequent and severe heatwaves, and potential impacts from rising lake levels and storm surges.
The risk of flooding is elevated due to Toronto's location near Lake Macquarie and several creeks. Climate change is projected to increase the intensity of rainfall events, leading to more frequent and severe flooding. This can damage property, disrupt infrastructure, and pose risks to human safety.
Heatwaves are another significant concern for Toronto. As temperatures rise, the risk of heatstroke and other heat-related illnesses increases, particularly for vulnerable populations. The urban environment can exacerbate the effects of heatwaves due to the urban heat island effect.
Rising lake levels and storm surges pose a threat to low-lying areas along the Lake Macquarie shoreline. This can lead to erosion, inundation, and damage to infrastructure and property. The impacts of these coastal hazards are expected to worsen as climate change progresses.
Addressing these climate risks requires a combination of adaptation and mitigation strategies. Adaptation measures include improving drainage infrastructure, implementing early warning systems for heatwaves and floods, and protecting coastal areas from erosion. Mitigation efforts involve reducing greenhouse gas emissions to slow the pace of climate change.
