Canada Post also announced a near doubling of the price of sending letters to $CAN1 (NZ$1.15) per stamp, effective March 31.
Canada Post delivers close to 10 billion letters and parcels each year to more than 15.3 million addresses across the country.
In its last annual report, it noted a 23.6 per cent drop in lettermail from 2008 as Canadians increasingly turned to email and paying household bills online.
This resulted in Canada Post losing $CAN73 million in the last quarter.
And it is now projecting a $CAN1 billion financial loss by 2020 unless it makes "fundamental changes to its business," it said in a statement on Wednesday.
These changes will include cutting between 6000 and 8000 staff, or up to 12 per cent of its workforce. The average age of its employees is 48 and the company said it expects nearly 15,000 will retire or leave the company in the coming years.
"The implementation of this plan means Canada Post can return to financial sustainability by 2019," it said, citing annual savings of up to $CAN900 million.
The figure does not include expected savings in labour costs and pension restructuring, which will be addressed through collective bargaining, it said.
