Water Events

CWWA Events

A major part of CWWA’s mandate is to facilitate national dialogue and information sharing.  We achieve this through our publications, the work of our committees, and our national events.

NWWC 2023


Niagara Falls, Ontario

November 12 = 15, 2023



This is CWWA’s flagship event and THE national conference for Canada’s water leaders.

We attract over 500 delegates from Canada’s water utilities, our private sector partners, provincial and federal governments, academia and the not-for-profit sectors.

While CWWA has hosted specialized events for over 30 years, this ‘consolidated’ event has merged all of the former events into ONE, all-encompassing national event focused on what the senior water manager needs to know.

This annual conference offers a wide-ranging technical program covering almost all aspects of the municipal water sector, while offering the best networking environment for Canada’s water leaders.

As THE national conference for the water utility sector, this event offers the best opportunity for sponsorship and exhibiting your products and services to Canada’s most senior water managers.

Recordings from the NWWC 2021 are currently restricted to delegates only. 

Window On Ottawa

in partnership with the 

water canada summit
June 7 – 9, 2023

The “Window” is CWWA’s signature policy workshop.

Window on Ottawa is CWWA’s signature event focused on federal water policy. It is a unique event where you learn about everything you ever wanted to know about water at the federal level…and were afraid to ask.

The most senior national policymakers from each federal department and agency are invited to the event—not to tell us what they’ve already released, but to tell us what they’re working on now and what is coming next.

The Window on Ottawa is a fascinating forum to engage with these policymakers at a very early stage and leave with an understanding of what to expect as a water leader.


















Join us for our Lunch and Learn webinar series. Each week we’ll hear updates from federal departments and agencies on the issues we couldn’t squeeze into the packed in person Canada Water Summit/Window on Ottawa agenda.

CWWA Workshops & Webinars

Much of our work is very specialized within specific streams that require a focus on specialized topics. Learning and information sharing can sometimes be best achieved though workshops.

In an effort to reach more of our members, and allow more to access critical information in an affordable and timely manner, we will be offering more webinars and electronically-accessed workshops.
