Historical and real-time water level and streamflow data. Upstream basin polygons here
Meteorological Data (measured)
- MSC Historical Climate Data
Historical hourly and daily gauge and radar meteorological data (web download month-by-month- for hourly data or year-by-year for daily data).- For downloading in bulk, try using the MSCr R package
- For visualization of data in space and time, try Green Kenue or the
Environment Canada Data Explorer
- ECCC Adjusted Daily Rainfall/Snowfall data (AdjDlyRS)

Meteorological Data (simulated/downscaled)
- Canadian Precipitation Analysis (CaPa)
Model-interpolated climate data generated from RDPS combined with gauge and radar data - Canadian Meteorological Centre’s Numerical Weather Prediction (NWP) models
Regional (RDPS), Global (GDPS), North American Ensemble (NAEFS) and seasonal forecasts in GRIB format. - CaSPAr – Canadian Surface Prediction Archive data portal
Historical ECCC regional climate prediction archives, available in NetCDF format - ClimateNA_MAP
North America-wide downscaled GCM climate data; monthly estimated variables from 1901-2010. - PCIC Downscaled GCMS
Canada-wide downscaled GCM climate data from the Pacific Climate Impacts Consortium (PCIC). Daily recip and min/max temperature in NetCDF or ASCII format for multiple scenarios.
Terrain Data
- Canadian Digital Elevation Model (CDEM) [preferred over CDED data]
Canadian national elevation data product - Canada Digital Elevation Data (CDED)
Canadian national elevation data product - Arctic DEM
High resolution (5-m or better) digital elevation model data north of 60 latitude - HydroSHEDS
Global hydrologically-conditioned digital elevation models south of 60 latitude at 3 arc-second resolution.
Provincial Data and Data Tools
- Ontario Integrated Hydrology Data
Harmonized Ontario Hydro Network-National Hydro Network stream and water body vector coverage with hydrologically corrected DEM and flow direction raster data for the province of Ontario. - Ontario Flow Assessment Tool (OFAT)”
Online map-based tool which creates watersheds, calculates watershed characteristics, executes simple hydrology models and reports water flow statistics.
Other Datasets
- CANOPEX – Canadian hydrometeorological watershed database
