Lac-Mégantic Rail Disaster

In the early morning of 6 July 2013, a runaway train hauling 72 tankers filled with crude oil derailed as it approached the centre of the town of Lac-Mégantic, Quebec. The tanker cars exploded and the oil caught fire, killing 47 people and destroying many buildings and other infrastructure in the town centre. The fourth deadliest railway disaster in Canadian history, the derailment led to changes in rail transport safety rules as well as legal action against the company and employees involved in the incident. Years after the derailment, re-building was still ongoing and many of the town’s residents continued to suffer from post-traumatic stress.

Indigenous Peoples' Medicine in Canada

Since time immemorial Indigenous peoples in Canada have been using plants and other natural materials as medicine. Plant medicines are used more frequently than those derived from animals. In all, Indigenous peoples have identified over 400 different species of plants (as well as lichens, fungi and algae) with medicinal applications. Medicine traditions — the plants used, the ailments treated, protocols for harvesting and application, and modes of preparation — are similar for Indigenous peoples across the country. In many Indigenous communities, there are recognized specialists trained in traditional medicine, and their practice often reflects spiritual aspects of healing as well as physical outcomes. In many cases, the therapeutic properties of Indigenous medicines are attributable to particular compounds and their effects on the body, but in other instances, their application is little understood by western medical practitioners. Within Indigenous communities, specific methods of harvesting and preparation of medicines are considered intellectual property of particular individuals or families.

Computers and Canadian Society

Canadians use computers in many aspects of their daily lives. Eighty-four per cent of Canadian families have a computer in the home, and many people rely on these devices for work and education. Nearly everyone under the age of 45 uses a computer every day, including mobile phones that are as capable as a laptop or tablet computer. With the widespread use of networked computers facilitated by the Internet, Canadians can purchase products, do their banking, make reservations, share and consume media, communicate and perform many other tasks online. Advancements in computer technologies such as cloud computing, social media, artificial intelligence and the Internet of Things are having a significant impact on Canadian society. While these and other uses of computers offer many benefits, they also present societal challenges related to Internet connectivity, the digital divide, privacy and crime.

Communications in the North

Communications have played a special role in the North. Terrain, climate and distance made it difficult for northerners to communicate with each other or with southern Canada before the advent of electronic media. In traditional times, Inuit messages were passed through personal contact.
