Lambeosaurus is a genus of large, plant-eating, duckbilled dinosaur. There are three known species of Lambeosaurus, all found in southern Alberta: L. clavinitialis, L. lambei and L. magnicristatus. In 1913, fossil collector Charles H. Sternberg discovered the first Lambeosaurus fossils in the modern-day Dinosaur Provincial Park area. A year later, Canadian paleontologist Lawrence Lambe named the fossils Stephanosaurus marginatus. Fellow Canadian William Parks then renamed the species Lambeosaurus lambei in 1923 in honour of Lambe. (See also Dinosaurs Found in Canada.)

A land cession is a transfer of land from one party to another through a deed of sale or surrender. Land cessions may also be referred to as land surrenders and land purchases. In Canada and the United States, Indigenous land cessions generally took place through negotiated treaties. There are cases, however, where Indigenous peoples claim that lands were taken unjustly. The Royal Proclamation of 1763 established the protocols for land cession in both Canada and the United States.

Surveys suggest that there may be as many as 2 million lakes in Canada. While some look like small scratches on the country’s surface, many are quite large. Nearly fourteen per cent of the world’s lakes with surface areas over 500 km2 are located in Canada. Below is a list of the largest of these large lakes. The list is ordered by the lake’s total surface area, not just the portions within Canadian borders.

Leguminosae, or Fabaceae, is the third-largest family of flowering plants, containing up to 650 genera and 18,000 species. Over 4,000 species are native to North America, most of which are members of the bean subfamily. They occur as scattered, secondary components of native vegetation. Over 2,000 species of milk vetch (genus Astragalus) alone occur worldwide, more than 40 in Canada. Other common native legumes are lupines (Lupinus), vetches (Vicia), locoweed (Oxytropis) and vetchling (Lathyrus). Most legumes, in association with strains of the bacterium Rhizobium,"fix" part of their nitrogen requirement and improve soils as green manure. Legumes are also a staple in the diets of both animals and humans.
