Quantitative measurements of rainfall, snowfall, the rate at which water penetrates into and moves through soil, streamflow, the rise and fall of LAKE and GROUNDWATER levels, and the evapotranspiration of water into the atmosphere are vital.

The Hypo Helmet (or “Smoke Helmet”) was an early gas mask developed by Newfoundland doctor Captain Cluny Macpherson during the First World War. Macpherson began working on the Hypo Helmet after the Germany army launched its first chlorine gas attack at the Second Battle of Ypres in April 1915. The British army began issuing the Hypo Helmet to Canadian and British soldiers in May 1915. The design was soon modified, resulting in the P, PH and PHG Helmets. By war’s end, 2.5 million Hypo Helmets had been issued. The gas mask was one of the most important innovations of the First World War.

Ice, including snow, is the solid phase of water. It is useful to think of it this way rather than as "frozen water" because water can achieve the solid phase through the freezing of liquid water or by direct deposition (sublimation) of water vapour, its gaseous phase.

The ice storm of 1998 was one of the largest natural disasters in Canadian history. Between 4 and 10 January 1998, sections of the St. Lawrence Valley from Kingston to Québec’s Eastern Townships received up to 100 mm of ice pellets and freezing rain — more than double the icy precipitation normally received in those areas in a whole year. The storm claimed as many as 35 lives, injured 945, and resulted in the temporary displacement of 600,000 people. Several roads were shut down and massive power outages occurred, cutting off electricity for nearly 1.4 million customers in Québec and over 230,000 in eastern Ontario. The total financial cost of the storm is estimated at $5.4 billion.

Canada’s most iconic highways were all built in the 20th or 21st centuries. Before the car became popular, good roads were hard to find once you left a city. As simple as they seem, it’s expensive to build and maintain roads. Rural routes were often treacherous for travelers. Modern highways connect our massive country. A few of them stand out for their length, origins, or wondrous landscapes.
