I forgot to mention that point, but consulting Canadians is indeed very important when it comes to creating new parks or new historical sites. Parks Canada considers it crucial to communicate with urban populations. However it is difficult to do so because there is a lot of noise from the various media.
We increasingly use social media to communicate with Canadians and consult them. As for the example you gave, it would be very important to use the various types of consultations we have used in the past. That is certainly a direction Parks Canada has already taken.
