I look forward to @commems posts for the potential Canadian Silver Dollar themes for the upcoming year but haven't seen one yet, so here's mine.
Obvious would be a King Charles III Silver Dollar.
A secondary theme could be for the 100th Anniversary of the Canadian Air Force. If not silver dollar then for a Toonie theme.
I see the 150th anniversary of the birth of Lucy Maud Montgomery, Anne of Green Gables Author, as a for sure commemorative. Either for the Loonie or Toonie.
There is also the 75th anniversary of Canada signing the NATO alliance.
