Over its more than 170 years in existence, Canada Post has faced multiple labour strikes like the one currently halting service across Canada. Canada’s first postal strike was in 1918, during a period of post-war inflation that caused prices to nearly double, drawing some parallels between then and now.
The Crown corporation also saw turbulent times throughout the 1960s and 1970s, with dozens of strikes and a deficit reaching some $500 million in 1980–81.
