Covering almost 790 000 km2 (8.6%) of Canada's land area, Brunisolic soils occur in association with other soils in all regions south of the permafrost zone.
Many Brunisolic soils have brownish B horizons without much evidence of clay accumulation. With time and stable environmental conditions, some Brunisolic soils will evolve to Luvisolic soils; others, to Podzolic soils.
Soils of the Brunisolic order are often regarded as being in a transitional stage of development. They are in the process of changing to either Luvisolic or Podzolic
