Just to let you know, the fare rules on the booking confirmation page on aircanada.com (i.e. the confirmation page after the flight is booked) don't reflect the addition of same day standby in the Western triangle. Wording on the booking confirmation page still reflects the old rules:

Same-day standby is available only to passengers travelling on a flight between Toronto and Montreal or Ottawa (connecting flights excluded), as well as to passengers travelling between Toronto Pearson (YYZ) and LaGuardia (LGA), John F. Kennedy (JFK) and Newark (EWR) airports.
