Lake of the Woods and the surrounding lakes is truly a huge fishery, and are governed by many different regulations and laws. Dependant on where you happen to be fishing, the catch and slot limits can vary drastically.
The best course of action if you are planning a fishing trip is to pick up a Recreational Fishing Regulations Summary book from the Ministry of Natural Resources. To access the MNR's Fishing Website, go to: http://www.mnr.gov.on.ca/en/Business/LetsFish/
Whatever lake or area you decide, be conscious of the different laws and always practice safe boating and fishing practices.
