Comment on climate change in Ontario. The Ontario Climate Change Discussion Paper 2015 emphasizes the need for both mitigation and adaptation activities in the province, noting that these can often be complementary. Public forums are being held across Ontario to receive comments. You can also provide input online.

Aviva to offer overland flood insurance for homes. While sewer backup insurance coverage is available in Canada, until now there has been next to no protection against damage that occurs from water that enters homes through basement windows or foundations. In response to increased demand following extreme weather events, Aviva is planning to announce the new coverage in May in Ontario and Alberta.

What kinds of trees are best for managing stormwater? A Master's thesis investigates which factors influence how much water trees slow down, evapotranspirate, and soak up. The study found that average deciduous street tree in Kamloops, BC absorbs between 2500 and 3500 meters cubed of stormwater annually.

Canada’s municipal infrastructure deficit tops $123 billion. Canada’s infrastructure budget has been slashed in the last 20 years while aging municipal systems are unable to keep up with changing weather patterns. Cities around the world are using green infrastructure to manage risk, prolong infrastructure lifespans, and save money.

Bioswales to prevent sewer backups. After two 1 in 100 year storms in three years, Cornwall, Ontario needed to adapt to protect its residents. The City is doing so using a combination of green and grey infrastructure, and public awareness campaigning. A demonstration bioswale installed as part of a road reconstruction and sewer separation project showcases the possibilities for further low impact development.

Clogged catch basins in Halifax cause flooding. Snow clearing is the responsibility of one City department, stormwater infrastructure another. Residents are filling in the gaps by attempting to clear storm drains on their streets, but under so much snow it’s hard for them to know where drains are located. With more snow and rain on the way, problems are unlikely to be resolved soon.
