Just checked the regs and this is a free fishing week end. No License required.
Quoted from Regs:
"Free Fishing Weekends
National Fishing Week July 6-14, 2013
Canada’s National Fishing Week is scheduled for July 6-14.
Alberta has teamed with other provincial, territorial and federal governments and private partners to promote the enjoyment and tradition of sportfishing. For more information please contact your local office of the Fish and Wildlife Division.
FREE Fishing Weekends July 13-14, 2013 & February 15-17, 2014. 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."
