The Moon River is a great place, just south of Perry Sound, Grisdales Westview resort on Woods Bay, and getting a guide for your first time would be a good idea the Moon can be tough, there are 2 that do a really good job, Graham Bristow or Jody Mills, the Moon isn't a numbers place but the quality of the fish is unbelievable.
There are also the French River, and Honey Harbor, but I don't have any info to offer on those areas.
There is a Canadian musky site, <url url="[Permission to view this media is denied]
