As part of its "Road to 2017" program, the Government of Canada has established a number of official milestones that it plans to mark.
In 2014, the milestones included:
- Centennial of the start of the First World War
- 75th anniversary of the start of the Second World War
- 150th anniversary of the Charlottetown and Québec Conferences
- Bicentennial of Sir George-Étienne Cartier's birth
Each of these four official milestones was marked by at least one commemorative coin (in the case of the World Wars, multiple coins were issued).
In 2015, Canada will officially celebrate:
- Bicentennial of Sir John A. Macdonald's birth
- 50th anniversary of the National Flag of Canada
It seems likely that one or more coins for each of these anniversaries is likely as a 2015 release.
