The Telus Convention Centre in Calgary, Alberta, will host 1,500 of the world's top child welfare researchers and professional for the four-day conference.
The society hopes to attract delegates from developing countries.
In 2014, the event will take place in Nagoya, Japan. In 2012, Istanbul hosted the conference.
ISPCAN president Jenny Gray added:"We are delighted that Canada will be hosting the 2016 congress and look forward to a stimulating event where professionals from all corners of the globe can come together to consider how we can protect our children from maltreatment and maximise their well-being."
Manmeet Bhullar, minister of Human Services, said: "We know there is more we can do to make sure children have the opportunity to live and grow in a nurturing, caring environment. Conferences like this are an excellent opportunity to work with partners from Alberta, across Canada, and around the world to ensure we are at the cutting edge of child protection methods and that we continue to work together to address the root causes of child abuse."
