| April 15, 1872 | Toronto Trades Assembly (possibly the original labour body in Canada) organized the first North American "workingman's demonstration". Some 10,000 Torontonians turned out to watch a parade and to listen to speeches calling for abolition of the law which decreed that "trade unions were criminal conspiracies in restraint of trade". |
| September 3, 1872 | Members of seven unions in Ottawa Canada organized a parade that stretched for more than a mile long. The parade stopped at the home of Prime Minister Sir John A. Macdonald. They brought him into a carriage and marched to the Ottawa City Hall by torch light. The Prime Minister was aware of the discontent of workers with the laws which made unions illegal so he made this declaration that his party would "Sweep away all such barbarous laws from the statute books". These laws were repealed by Parliament later that year and the tradition of holding parades and demonstrations was continued on into the early 1880s. |
| July 22, 1882 | The Toronto Trades and Labour Council (the successor to the TTA) organized the annual demonstration and parade. Peter J. McGuire of New York was invited to attend and speak at this occasion. |

| September 5, 1882 | The Central Labour Union held its first Labour Day holiday in New York City. A second Labour Day was again held a year later on September 5, 1883. |
| 1884 | The first Monday in September was selected as the holiday and the Central Labour Union urged similar organizations in other cities to also celebrate a "workingman's holiday" on that date. |
| February 21, 1887 | Oregon passed the first bill to become law making Labour Day an official holiday. |
| June 28, 1894 | The United States Congress passed an act making the first Monday of September of each year a legal holiday in the District of Columbia and the territories including all Federal workers in all states. The individual States still had to enact their own legislation which 31 States had done already by this time. |
| July 23, 1894 | The Canadian Government enacted legislation making Labour Day, the first Monday of September of each year into a national holiday. |
