From https://kitchissippiward.ca/content/time-capsule (visit that link to vote too):
During the Mayor’s 2017 State of the City address, he announced that as part of the 2017 celebrations, we would be assembling a time capsule that would be opened by Ottawa residents in 50 years’ time, when Canada will be celebrating its 200th anniversary.
In order for this to be a successful time capsule, the Mayor is looking for our constituent’s contributions. We have taken suggestions from the community and would now ask you to vote on your choice for item to be included in this time capsule, to represent Kitchissippi Ward from 2017. You have until Tuesday, September 26 to vote and we will announce the preferred item on Wednesday, September 27.
