As labor strikes expand across Canada, conditions are added to to the Immigrant Act to: "add more restrictive regulations to its immigration policy in an effort to protect the country from dangerous ideologies and subversive activities" (Canadian Museum of Immigration, n.d.).

The amended categories include: "those who disbelieved in or opposed organized government, those advocating for the assassination of public officials, those advocating or teaching the unlawful destruction of property and those guilty of espionage and treason. Other inadmissible immigrants included the illiterate, individuals of chronic psychopathic inferiority, persons with chronic alcoholism, those living with tuberculosis and anyone certified as being mentally or physically defective."
