It is not necessary to buy the Seasonal Lockage Permit ($8.80/ft) to do the Trent-Severn Waterway. Get The Transit One-Way Permit ($4.65/ foot). The Transit One-Way Permit allows the boater to travel the entire Trent Severn from Trenton to Port Severn, i.e. a one-time transit where vessels go through each lock station only once. The Transit One-Way Permit is not available from Parks Canada. Buy it directly from Trent-Severn Waterway National Historic Site P.O. Box 567 Peterborough, Ontario Canada K9J 6Z6 Tel: 705-750-4900 Teletypewriter (TTY): 705-750-4949 Fax: 705-742 9644 Tel (Toll-free in North America Only): 1-888-773-8888 Email: _Ont.Trentsevern@pc.gc.ca_ (http://www.pc.gc.ca/eng/lhn-nhs/on/trentsevern/courriel-email.aspx) Also, I would not buy the Seasonal Overnight Mooring Permit ($9.80/ft). Pay as you go each night ($.90/ft). Break even point is 11 nights.

If you are planning both Trent Severn and Rideau in the same season then seasonal permits from Parks Canada are more economical.
