NPRI · GHGRP · Ontario deadline June 1
NPRI & GHG reporting for Ontario facilities —
defensible numbers before the June 1 deadline.
Automate NPRI and federal GHG reporting for Ontario manufacturers. Mass-balance reconciliation, ECCC emission factors, substance thresholds (Cr⁶⁺, Ni), and peer benchmarking against 1,400+ Ontario facilities. Stop scrambling every May.
Why every May feels like a fire drill
The National Pollutant Release Inventory deadline — June 1 for most Ontario facilities — compresses a year of operational data into a three-week scramble. Plant managers pull fuel receipts from filing cabinets, EHS coordinators reconcile bath chemistry logs against production records, and sustainability leads discover the spreadsheet from last year has hardcoded factors that don't match this year's ECCC National Inventory Report. The result is a filing that meets the deadline but doesn't survive verifier scrutiny — or worse, under-reports a substance like chromium VI that triggers mandatory NPRI reporting at just 10 kg released.
What VantageHSG automates in the NPRI workflow
Instead of annual data archaeology, VantageHSG ingests documents as they're produced throughout the year. Fuel slips flow through OCR into Scope 1 combustion calculations with ECCC NIR factors. Bath chemistry logs reconcile metal added vs. metal plated vs. metal wasted for electroplating facilities. Production records feed clinker-ratio mass balance for cement plants. Each stream is calculated continuously, and the NPRI export format is generated on demand — not rebuilt from scratch every May. Substance thresholds (Cr⁶⁺ at 10 kg, nickel, zinc, VOCs) are monitored in real time so you see what's in scope before the regulator does.
How you compare to Ontario peers before you file
Public NPRI and GHGRP data covers 1,400+ Ontario facilities. VantageHSG's Network Intelligence module benchmarks your totals against sector medians — steel and foundries in Hamilton, cement in the Golden Horseshoe, automotive parts in Windsor and Oshawa. If your reported intensity is 40% above the cohort median, that's a conversation to have internally before the filing goes public — not after a journalist or competitor notices. Our free NPRI Benchmark Explorer tool lets you check your position today with no signup.
From annual filing to continuous compliance
NPRI is an annual event, but the data behind it is produced daily. VantageHSG treats NPRI as one output of a continuous carbon data pipeline — the same pipeline that feeds Bill C-59 compliance statements, OEM carbon questionnaires, and CBAM declarations. Start with one document to see the lineage. Move to a paid pilot to prove ingestion and mass-balance quality on your actual facility. Deploy at $299/month for single-facility Scope 1 and 2 with NPRI-ready exports.
Why VantageHSG
Built for Ontario manufacturers — not retrofitted from generic SaaS.
- ✓ECCC NIR combustion factors — updated with each inventory release
- ✓NPRI substance threshold monitoring (Cr⁶⁺, Ni, Zn, Cd, VOCs)
- ✓Bath chemistry mass balance for electroplating
- ✓Public peer benchmarks from 1,400+ Ontario facilities
- ✓Verifier-ready export formats
Common questions
Is VantageHSG a replacement for NPRI-Online?
No. We produce the calculated data, mass balances, and substance totals that you enter into NPRI-Online. We automate the math and lineage; you retain responsibility for submission and attestation.
What if we're below the 10,000 tCO₂e GHGRP threshold?
Many Ontario manufacturers are below federal GHGRP but still have NPRI substance reporting obligations — especially electroplating, chemical, and metal finishing operations. VantageHSG tracks substance-level thresholds independently of the GHG threshold.
Can we start mid-year?
Yes. Ingest this year's documents retroactively and we'll reconcile against your prior filing to show deltas and flag discrepancies before next June.
