The Battle of Paardeberg was the first time men in Canadian uniform, fighting in a Canadian unit, made war overseas. It also inspired one of the first remembrance ceremonies in Canada: from 1900 until the end of the First World War, Canadians gathered not on November 11, but on February 27 — Paardeberg Day — to commemorate the country’s war dead and its achievements in South Africa (see also Remembrance Day in Canada).

The cereal was first developed at the Hospital for Sick Children in Toronto in 1930 by pediatric doctors Theodore Drake and Frederick Tisdall under the supervision of physician-in-chief Alan Brown. Pablum became commercially available in 1934 through an agreement with the Mead Johnson & Company and was used as a brand name through the early 21st century.

The Pacific Ocean is the world’s largest ocean. It covers more than 30 per cent of the Earth’s surface — an area roughly the same as the Atlantic and Indian oceans combined. Canada’s relationship with the Pacific Ocean is synonymous with the West Coast of British Columbia. The province’s entire ocean shoreline, including the coasts of Vancouver Island and Haida Gwaii, form Canada’s Pacific coastal region. More than 75 per cent of the province’s 5 million residents live within 50 km of the coast.

The Pamajewon case (1996) (also known as R. v. Pamajewon) was the first case in which First Nations in Canada argued an inherent right to self-government before the Supreme Court. Spearheaded by two Anishinaabe First Nations, Eagle Lake and Shawanaga, the claimants argued that the Indigenous right to self-government included a right to control gambling practices on reserves. The Supreme Court ruled that these First Nations did not have rights to high-stakes gaming under self-government.
