In Canada, the duty to consult and accommodate with Aboriginal peoples arises when the Crown contemplates actions or decisions that may affect Aboriginal or Treaty rights. This duty arises most often in the context of natural resource extraction such as mining, forestry, oil, and gas. It is very difficult to practically separate the duty to consult and accommodate because consultation may lead to the fulfillment of the duty to accommodate and consultation is meaningless if accommodation is excluded from the outset. As such, the two are intertwined and must be addressed together.
