Parks Canada offers OPUS card holders a 2 for 1 discount on entries fees in participating National Historic Sites.
How does it work? The user of the OPUS card must present his OPUS card at the entrance of any participating site to obtain the discount. Out of the two fees, the visitor will only pay the highest fee. For example, an adult with a child will have to pay the higher entry fee, which is the adults fee and the childs entry will be free.
Value of the offer: Entrance fees vary by location, from $ 3.90 to $ 15.18 per person
