The Aboriginal Apprenticeship Board of Ontario (AABO) is a not-for-profit organization dedicated to increasing the number of Aboriginal people in the trades in Ontario.

The AABO is the embodiment of the Ontario-based Aboriginal Apprenticeship Strategy as defined in the document "Supply Meeting Demand." Its purpose is to ensure that the components of the Strategy are well articulated through a plan of action, which will have measurable and positive results throughout the province.

AABO is composed of Aboriginal Skills and Employment Training Strategy (ASETS) holders to whom the Board is ultimately responsible. The Aboriginal Apprenticeship Board of Ontario works in conjunction with a Partnership Advisory Committee comprised of industry and government representatives.
