Canada holds a fifth of the world’s freshwater, yet many of its communities still face boil water advisories, phosphorus-fueled algae blooms, and shrinking aquifers. While water feels abundant here, the truth is more complicated and more urgent.

In this episode of Ideas for Impact, we sit down with Kariann Aarup, Head of Program Partnerships at AquaAction, a national nonprofit helping young innovators design and deploy real-world freshwater solutions. With more than 80 water tech ventures launched through their AquaHacking Challenge and AquaEntrepreneur programs, AquaAction is proving that early-stage ideas—when rooted in local knowledge and built with intention can shift how we respond to one of Canada’s most pressing environmental challenges.

From a startup turning blue-green algae into biofuel, to AI-powered infrastructure tools that predict water main failures before they happen, Kariann walks us through the powerful solutions emerging from Canada’s youth and what it takes to turn a prototype into impact.

We explore:

• The biggest threats to freshwater in Canada right now (and why the myth of abundance is dangerous)
• Why youth-led innovation offers a radically different mindset around environmental entrepreneurship
• How AquaAction matches local water problems with student-driven tech innovation
• The real barriers to scaling water tech regulation, public sector procurement, and slow adoption cycles and what AquaAction is doing to change that
• The role of mentorship, community, and experiential learning in building a generation of water-aware leaders
• Why designing with water at the centre could change how we build everything from cities to clothing

If you’re curious about what the future of water looks like in Canada—and how entrepreneurship, sustainability, and systems change are starting to intersect in real ways—this conversation is for you.
