Here's the quote from the
Fishing Regs:
"FREE Fishing Weekends July 7-8, 2007 & February 16-18, 2008
To encourage folks to give fishing a try, any person may fish without an Alberta Sportfishing Licence on these dates but they must follow all other rules and regulations as outlined in this guide. These weekends coincide with Canada’s National Fishing Week and Alberta Family Day."
