This data set was collected by Sofia Rosero from digital and paperback copies of Reports by the Canadian Department of Labour. It presents the official statistics of strikes and lockouts in Canada between 1901 and 1916. There is no official data available before this time because recollection of data was only possible after the establishment of the Department of Labour in 1900. On the cases when extra information on the events has been found, there will be a link at the bottom of each year directing to the websites where this information can be found.
