3.4 Data completeness

Completeness of data varies geographically, with the underlying data source (see individual data sources in section 3.1 for details). Data from sources including provincial, territorial and federal governments, as well as non-government organizations, were considered for inclusion. A minimum mapping unit of one hectare or less was required.
