    Lizard Species in Canada

    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.

    Mackenzie Valley Pipeline Proposals

    In 1970, the Canadian government introduced guidelines for the development of a pipeline corridor south from the Mackenzie River delta to Alberta and the United States. Energy companies have since proposed three separate projects to transport natural gas by pipeline along this route — the Arctic Gas Pipeline, the Foothills Pipeline and the Mackenzie Gas Project — with an oil pipeline likely to follow in the first two cases. However, due to high costs, engineering challenges, environmental concerns, Indigenous land claims and changing markets, none of these pipelines has been built.
