Until it was successfully controlled, that the Rideau River flooded each spring was not a surprising fact to Ottawans. Although the degree to which it did varied considerably over the years, that it did at all was largely a sure bet.
May 15, 1965 was the fourteenth annual Tulip Festival and it featured the first ever Tulip Festival parade.
In any number of ways, the 1885 Northwest (or Riel) Rebellion occupies something of an uneasy (when it’s not forgotten) space in Canadian history. Nevertheless, the Rebellion was one of the earliest opportunities that the young Dominion had to demonstrate some of its firepower and a number of cities erected memorials and statues dedicated to the event. In his classic standard Ottawa Old & New, Lucien Brault described the contribution as such:
When news of the Riel Rebellion reached Ottawa, military authorities ordered the formation of a volunteer militia corps in Canada. Ottawa’s quota was 53 sharpshooters, to be raised from the Governor General’s Foot Guards and the 43rd Regiment. The answer was so enthusiastic that names of volunteers had to be drawn. These soldiers served at the battle of Cut Knife Hill where the Indian Chief Poundmaker was defeated by Colonel Otter. During the action, two of the Ottawa Sharpshooters were killed. A monument on Elgin St., formerly at the entrance of Major Hill Park, commemorates their fait d’armes. 
The Ottawa Company of Sharpshooters returned from the west in July 1885 and a fund was quickly begun in order to erect a monument to their achievement. By 1888, sufficient funds had been collected and that November, the new memorial was revealed at the entrance to Major’s Hill Park, where Chateau Laurier currently sits. Of course, the growing city did not have the luxury of keeping such a monument in what would become a central location and it was relocated in October of 1911 to make room for the hotel’s construction .
The memorial was next placed on the grounds of Ottawa’s City Hall (constructed in 1877), just down Elgin, past the Russell House Hotel. That did not mark the end of the journey for the memorial, however. In 1931, City Hall burned down.  Although city hall was gone, the Sharpshooters’ memorial, along with the more recent Boer War statue, remained on site until the construction of the National Arts Centre began in 1965.
Once again, the memorial had to move. Site preparations for the construction of the new Canadian Centre for the Performing Arts (now the National Arts Centre) began in 1964/65. When crews were removing the statues (to Confederation Park), a jar containing a commemorative medal and some paper was found in the base.  Both memorials remained at peace until 2006, when the Sharpshooters’ Memorial was moved across Laurier to rest outside of the Cartier Square Drill Hall. The Boer War memorial, however, remains in its more sylvan home at Confederation Park.
