As a storm raged outside, the constantly ringing phones went unanswered at Environment Canada’s Toronto offices last Thursday. Like many other workplaces in the city, it was shut down - by the worst series of blizzards ever to strike Toronto.

    Trans Mountain Pipeline Expansion Project

    The Trans Mountain Expansion is a project to build about 980 km of new pipe, most of which will run parallel to the existing Trans Mountain oil pipeline. The new line will carry diluted bitumen, or “dilbit,” from Edmonton, Alberta to Burnaby, British Columbia. The expansion will increase the pipeline route’s overall capacity from 300,000 barrels per day to 890,000 barrels per day. The project’s first owner, Kinder Morgan Canada, sold it to the Government of Canada in 2018. The Trans Mountain Expansion has been a focus of environmental and economic debates, as well as political conflicts. The $12.6 billion project is now under construction.

    Transportation in the North

    Inuit and subarctic Indigenous peoples have traversed the North since time immemorial. Indigenous knowledge and modes of transportation helped early European explorers and traders travel and survive on these expanses. Later settlement depended to an extraordinary degree on the development of transportation systems. Today, the transportation connections of northern communities vary from place to place. While the most remote settlements are often only accessible by air, some have road, rail and marine connections. These are often tied to industrial projects such as mines.

    Trees

    Trees are single-stemmed, perennial, woody plants taller than 3 m and exceeding 8 cm in diameter at breast height; shrubs are multistemmed and smaller. These definitions are somewhat arbitrary, since many species (eg, willow, alder, cherry, maple) can grow as trees or shrubs, depending on the environment. Counting the 30-odd shrubs that assume tree form under favourable conditions, there are about 140 native Canadian trees.

    Triceratops

    Triceratops is a genus of plant-eating, horned dinosaur. There are two species of Triceratops: T. Horridus and T. Prorsus. Triceratops lived between 68 million and 66 million years ago during the Late Cretaceous period. The name Triceratops is of Greek origin and means “three-horned face.” Triceratops remains are among the most abundant dinosaur fossils found, though this is more true in the United States than in Canada. In 1921, paleontologist Charles M. Sternberg found the first Triceratops fossil from Canada, discovered in southern Saskatchewan. Paleontologists have also discovered Triceratops fossils in Alberta. (See also Dinosaurs Found in Canada.)
