$4 before 10am and 3-7pm M-F
$2 all other times (and always for youth)
Calgary's system of nickel and dime increases every year has been so stupid (especially considering lack of electronic purchase options).

Revise ticket books to $2 increments (or halfway perforated $4 tickets).
Not sure how I even feel about charging for 6 year olds to take the bus. Maybe age 6-17 are $2 during peak times, and free during off times...
