Groundhog River Waterway Provincial Park is a large northern Ontario waterway park. Ontario Parks lists the park at 11,036 hectares, established in 2006.
The southern limit of the park is about 21 kilometres southeast of Foleyet, while the northern boundary on the Mattagami River is about 54 kilometres northeast of Kapuskasing. Ontario Parks says there are no visitor facilities.
Ontario Parks describes Groundhog River as a highly diverse site representing about 22 landform-vegetation combinations. Dominant landforms include weakly broken ground moraine and lacustrine deposits, with mixed conifer and mixed deciduous forests.
The river also has self-sustaining sturgeon fisheries, and brook trout occur in feeder streams. As a large northern Ontario river, Ontario Parks says it offers a remote canoeing experience.
The skill note is essential: the official page identifies the canoe route as an advanced-level river trip. That makes this a page for experienced paddlers and route researchers, not casual first-time canoe planning.
The distance between the Foleyet-area southern limit and the Mattagami River boundary near Kapuskasing also signals scale. Route plans should account for remoteness, communications, weather, and evacuation options.
Plan around advanced canoe route research, remote river travel, sturgeon and brook trout habitat awareness, fishing regulation checks, landform and forest context, water levels, maps, and emergency planning.
Confirm access, route maps, advanced skill requirements, water levels, camping permissions, fishing rules, no-facility expectations, weather, alerts, emergency plans, and park rules through the official Ontario Parks source before travelling.
