These resources were developed as part of our award-winning RAIN Community Solutions program, a collaborative initiative led by Green Communities Canada and our member organizations from 2010 to 2021/2022. The program aimed to advance green stormwater infrastructure (also known as low impact development), restore the urban water cycle, and reduce runoff pollution. RAIN received national recognition, including the 2015 Minister’s Award for Environmental Excellence and the 2014 Council of the Federation Excellence in Water Stewardship Award.

Now a legacy program, RAIN has been integrated into our broader green infrastructure work through Living Cities Canada, where our commitment to advancing sustainable, community-led stormwater solutions continues.
