The Canadian Labor Day is basically another name for May Day except it is not celebrated on May 1rst like most countries. It marks the beginning of Spring and celebrating the work force of the country.
To enjoy such a holiday workers and their families can have a day off from their tiring work hours. All workers, schools and government jobs get the day off as it is a national holiday.
This day came to be when the United States government tried to extend the hours of a regular work day to 8 and there were riots that broke out around the country. Learning from their mistakes the U.S and many other countries made a holiday for the hard workers that support the country.
