Canadian agriculture has experienced a markedly distinct evolution in each region of the country. A varied climate and geography have been largely responsible, but, in addition, each region was settled at a different period in Canada's economic and political development. The principal unifying factor has been the role of government: from the colonial era to present, agriculture has been largely state-directed and subordinate to other interests.

Lizards are reptiles that belong to several suborders within the order Squamata (which also includes snakes). They are the most diverse group of living reptiles and are found on all continents except Antarctica. There are six species of lizard currently found in Canada. In addition, one species, the pygmy short-horned lizard, is extirpated. This means that, while it continues to live in other parts of its range, it is no longer found in Canada. Five of the six lizard species in Canada are native, while the sixth, the common wall lizard, is introduced from Europe.
