Kilometres per hour (km/h or kph) is the standard unit for measuring speed in Canada, used on all road signs, speedometers, and transportation regulations. Canada adopted the metric system in the 1970s, replacing miles per hour. Common speed limits include 50 km/h on urban streets, 80-90 km/h on rural roads, and 100-110 km/h on highways. Municipalities set speed limits on local roads within provincial guidelines, using traffic studies and safety considerations to determine appropriate speeds for different areas. Understanding metric speed measurements is essential for all drivers and helps ensure road safety across Canadian communities.
