Cape Breton Highlands National Park (established 1936) stretches across the northern tip of Cape Breton Island.

Bruce Peninsula National Park (established 1987, 156 km2) consists of a former provincial park and private lands acquired on a "willing buyer-willing seller" basis. Over 75% of the total area of the park has been acquired.

Earth's surface experiences change driven by relief, sea level, hydroclimate and human activity. Extreme hydroclimatic events combined with human activity on steep slopes and/or adjacent to low-lying coasts generate natural hazards.

A river is a course of water, usually growing in volume between its source and its terminus in an ocean, a lake or another river.

The size of a snowflake is related to how far the snowflake has fallen from the sky and to how well colliding snow crystals stick to each other. The largest snowflakes are usually observed near 0° C because of the increased forces of adhesion at these temperatures.

Central US lows, entering Canada somewhere between Manitoba and Québec, are of major environmental significance because they pass through the industrial heartland of the US and frequently bring ACID RAIN.

Gold (Au) is a bright, shiny, yellow metal, notable for its high density (19.3 times the weight of an equal volume of water) and valued for its extreme ductility, strong resistance to corrosion, lustrous beauty and scarcity.

One of Canada’s most high-profile highway tragedies occurred on 6 April 2018, when a bus carrying 28 members of the Humboldt Broncos junior hockey team collided with a transport truck at a highway intersection near Tisdale, Saskatchewan. The crash killed 16 team members: 10 players and 6 staff. It also led to new truck-driver training and licensing regulations and increased awareness about the availability and use of seat belts among bus passengers.

In Canada, bush flying refers to aviation in sparsely populated northern areas. Flight in the Arctic and the “bush” of the Canadian Shield developed between the world wars. Early bush pilots faced the challenges of cold weather and vast distances between communities. Given the rarity of airstrips, their planes were often equipped with skis or floats so that they could take off and land on water or snow. This type of aviation was key to developing services and industries in the North. While the romantic image of the bush pilot is associated with the past, bush flying continues to serve remote communities in Canada.

The $7.9 billion Northern Gateway project was a pipeline proposal that Enbridge put forward in 2008. Northern Gateway would have carried diluted bitumen (“dilbit”) about 1,170 km from Bruderheim, Alberta to a terminal on the Pacific Ocean at Kitimat, British Columbia. Enbridge claimed that the project would create $1.2 billion in tax revenue for BC, as well as 560 jobs. The Federal Court of Appeal overturned the pipeline’s approval in 2016. That same year, the Liberal government of Prime Minister Justin Trudeau rejected the project.

A forest region is a major geographic belt or zone characterized by a broad uniformity both in physiography and in the composition of the dominant tree species. Canada can be divided into eight forest regions.

A timber slide is a water-filled chute or runway built to carry “cribs” of timber (see Rafts) around rapids and falls. Similar devices for individual pieces of wood were called “flumes.”

Canada may be divided into seven physiographic regions: Arctic Lands, Cordillera, Interior Plains, Hudson Bay Lowland, Canadian Shield Forest Lands, St Lawrence Lowlands and Appalachia.

Natural regions are intended to describe areas of the Earth's surface which possess similar qualities or attributes. They may refer to either land or water, and can vary in size. The term “natural region” is often used interchangeably with the word “ecozone.”

The most common and widespread bear in Canada, the black bear (Ursus americanus) is found predominantly in forests of every province and territory, with the exception of Prince Edward Island.

​Over the course of Canada’s history, marine disasters have occurred along the country’s coasts as well as in its freshwater lakes.

Radiation fog forms most commonly as moist air is cooled below its dew point, ie, the critical temperature at which air can no longer hold all its water vapour.

SABLE ISLAND, a crescent-shaped sandbar 300 km east-southeast (160 nautical miles) of Halifax, is also infamous for its shipwrecks, and is known as "the Graveyard of the Atlantic," as its shifting sands have been the site of over 350 such incidents.

Hornet is the common name for wasps in the genus Vespa. They are members of the insect family Vespidae in the order Hymenoptera, which also includes other social wasps like yellowjackets and paper wasps. There are 22 species of hornets worldwide, none of which are native to Canada. However, three introduced species have been found here: the European hornet (Vespa crabro) in southern Ontario and  Quebec, and the Japanese yellow hornet (Vespa simillima) and Asian giant hornet (Vespa mandarinia) in coastal British Columbia. The bald-faced hornet (Dolichovespula maculata) is native to Canada, but is actually a species of yellowjacket.

Lentil is a small leguminous seed belonging to the Lens culinaris species and the legume (Fabaceae) family.
