Did you know that Labor Day orginated Canada out of a labor dispute?

Did you know that:

Labor Day is a United States federal Holiday observed on the first Monday in September.

The holiday originated Canada out of labor disputes in the 1870s, which resulted in legalization and protection of union activity in 1872. The parades held in support and the printers' strike led to an annual celebration in Canada. In 1882 American labor leader Peter J. McGuire witnessed one of these labor festivals in Toronto. Inspired, he returned to New York and organized the first American "labor day" in that same year: September 5, 1882, 127 years ago.
