OpenIO-Canada is an open-source Multi-Regional Environmentally Extended Input-Output (MREEIO) model developed by CIRAIG, designed to estimate the life cycle environmental impacts of products and services in Canada. It operates at the provincial level across all 13 Canadian provinces and territories, covering 492 commodities and 33 GHGs, as well as around 300 pollutants, 67 mineral resources, water consumption, energy use, and plastic waste. The model provides emission factors (kgCO₂e per CAD) for 6,396 commodities produced across Canada and 9,600 commodities produced outside Canada. International trade is modelled by connecting OpenIO-Canada to the EXIOBASE global MRIO database, ensuring that imported goods are characterised using the economic structure of their country of origin rather than assuming Canadian production conditions.

OpenIO-Canada operates at basic prices, and purchaser price emission factors are also available using average trade and downstream transport margins.

Climatiq provides two emission factor variants for each activity, both at purchaser price (inclusive of taxes, retail margins, and distribution costs):

Without endogenisation — the emission factor covers the supply chain of the commodity but excludes capital goods such as buildings, machinery, and software.

With endogenisation — the emission factor additionally accounts for capital goods, integrating the consumption of fixed capital into the full value chain description.
