Coverage and interpretation

Coverage is limited to published source geographies and releases. Missing, suppressed and unavailable observations must not be treated as zero. Use Canadian DGUIDs and characteristic definitions; US GEOIDs are not interchangeable.

The active release shown here is a catalog snapshot. Check the live catalog and response provenance for current readiness. The underlying public source and Geoamcan access terms are separate; consult the source’s licensing and attribution requirements.
