University of Guelph · Ontario, Canada
Ontario municipalities face a compliance crisis. MECP's CLI-ECA framework requires system-wide stream monitoring, but the sensors aren't ready, the placement science is unsolved, and the costs are prohibitive. We're fixing that.
The problem
Ontario's MECP CLI-ECA framework requires every municipality to monitor receiving watercourses as a connected system. Three fundamental research problems stand between municipalities and affordable compliance.
Commercial turbidity, conductivity and flow sensors were not designed for unattended Ontario stream deployment. Biofilm fouling, ice, debris and freeze-thaw cycles cause drift and failure within weeks. No validated low-cost solution exists for real creek environments municipalities will actually monitor under CLI-ECA.
MECP guidance says "strategically chosen" monitoring locations, but provides no transferable methodology. Where you place a station dramatically affects what signal you detect. A sensor in the wrong reach detects nothing useful. Optimal siting requires hydrological modelling most municipalities cannot perform.
When can a calibrated surrogate sensor replace physical sampling, and when is it inadequate? The turbidity-TSS and conductivity-chloride relationships are site-specific and season-dependent. Deploying autosamplers everywhere is unaffordable; relying on surrogates without validation is indefensible. The decision framework does not yet exist.
Each municipality is developing plans independently, duplicating costs, expertise gaps, and procurement across 500+ systems. Guelph's monitoring program alone spans 8+ subwatersheds with multiple autosamplers. A coordinated approach changes everything.
Research programme
From validated sensor design to sector-wide adoption, the HUB closes the loop between detection and action.
Low-cost, winter-robust sensors and flow-triggered autosamplers validated for Ontario streams. Surrogate sensing decision frameworks, establishing when turbidity and conductivity proxies are sufficient and when physical sampling is required.
Telemetry infrastructure (LoRaWAN, cellular), cloud QA/QC, trend detection algorithms and automated MECP-aligned annual performance dashboards, turning raw sensor data into defensible compliance reports.
IoT-actuated bioretention, detention and green infrastructure, dynamically optimising asset performance using real-time data, closing the loop from receiver monitoring to active stormwater management.
Cost-benefit models and governance frameworks for Conservation Authority-led regional monitoring networks. Business cases demonstrating direct cost savings versus independent municipal programs.
MECP monitoring plan templates, optimal placement methodology tools and qualified professional training pathways, driving uptake across 500+ municipalities who cannot wait for bespoke solutions.
The opportunity
The 24-month compliance clock starts when MECP publishes final guidance. Municipalities that wait will face urgent, expensive, fragmented solutions. Partners who invest now shape the tools the whole sector will use.
The HUB builds on the $8M CERC microSCAPE program in IoT water monitoring at the University of Guelph, combining deep sensor engineering expertise with established municipal and conservation authority relationships across Ontario.
Australian and US IoT water monitoring research does not address ice, freeze-thaw, or snowmelt sensor challenges. Ontario-specific validation is a genuine research gap, and a competitive advantage for HUB-validated technologies.
Partner investment
Industry cash is leveraged with NSERC Alliance and Infrastructure Canada / FCM Green Municipal Fund. Every dollar invested directly reduces the cost of mandatory compliance.
Municipalities, regions, Conservation Authorities and sensor companies with a direct stake in CLI-ECA compliance outcomes.
Consultants, software platforms and smaller municipalities seeking co-developed guidance and early access to validated tools.
MECP, conservation authorities and academic institutions contributing data, regulatory co-development and field access.
NSERC Alliance matches industry cash at approximately 1:1. A $5M industry commitment leverages an equal federal contribution, making the research program achievable without proportionally large public investment.
