Be sure to check on the regs. In most Ontario areas, muskies don't come it until the first or second week in June. No targeting out of season.
If you're looking to do an easy "drive to" fishing experience, you may consider the Kawartha Lakes....Pigeon, Buckhorn, Chemong, Sturgeon, Balsam and Cameron are all good choices for muskie fishing. Only about a 6-7 hr drive. Good Luck!
