Some rules were introduced during wars, disasters, or economic crises. A surprising number lasted long enough to become part of ordinary life.
1. Daylight Saving Time
The U.S. adopted daylight saving time during World War I as a wartime measure intended partly to conserve energy.
Although the policy was later repealed and restored, seasonal clock changes eventually became a recurring feature of American life.
2. Emergency Banking Restrictions
During the Great Depression, President Franklin Roosevelt declared a national bank holiday in March 1933.
Banks were temporarily closed while the government examined their financial condition. The emergency measures helped reshape federal oversight of the banking system.
3. Wartime Price Controls
During World War II, the U.S. government imposed price controls and rationing on numerous goods.
The restrictions were designed to prevent inflation and ensure supplies reached the military. Many disappeared after the war, but the episode permanently changed expectations about federal economic intervention.
4. The Canadian War Measures Act
Canada’s War Measures Act was created in 1914 as wartime emergency legislation.
It was later invoked during the 1970 October Crisis, decades after its original purpose. Canada eventually replaced it with the Emergencies Act in 1988.
5. Britain’s Emergency Powers
Britain introduced sweeping emergency powers during World War I and expanded them during World War II.
Some wartime powers were later incorporated into permanent legislation, showing how extraordinary measures can gradually become part of normal government authority.
6. Emergency Disaster Powers
Modern governments maintain emergency laws allowing authorities to temporarily restrict movement, close businesses, evacuate areas, or redirect resources during major disasters.
In Ontario, for example, emergency legislation gives the government powers including regulating movement and closing places when strict conditions for an emergency are met.
