The original 'core' area of Wabakimi Provincial Park that was regulated in 1983 comprised about 155,000 hectares (ha). In 1997, the park was expanded by about 737,000ha creating a total area of 892,061ha. Wabakimi is Ontario's second largest provincial park, larger than Algonquin or Quetico and Woodland Caribou combined but with far fewer visitors and no entry quota or campsite assignment systems.
