If you fish Walleye and Pike like me I can give you some ideas from the perspective of a guy with no sled or ATV, just my toboggan and boots. Some easy to get to spots where I have had success:
Ottawa River, off Kiska Beach (Lamure Bay), find drop off or large hump 100m off beach, I can send cords.
Black Bay, walk off Rantz Rd launch, follow the pattern of ice huts
Lake Dore, public launch off lake Dore Road on Beiderman Rd, usually quite busy but pike and walleye are there
