Mary Malcolmson organized the first Canadian Girl Guides Company to be officially registered in St. Catharines, Ontario; their registration is dated 1910-01-11. A park in St. Catharines was later named for Mary Malcolmson. Other Guide Companies were registered later in 1910 in Toronto, Moose Jaw and Winnipeg. The First Toronto Company held the first-recorded Girl Guide Camp in Canada on the banks of the Credit River in June 1911. By 1912, the movement had spread to all parts of Canada, and had become so popular that on 24 July 1912 Agnes Baden-Powell created Mary, Lady Pellatt "Chief Commissioner of the Dominion of Canada Girl Guides". Many Guide events were held at Lady Pellatt's home, Casa Loma, in Toronto. It is now a tourist attraction with a special Girl Guide display.
