Although both parties have agreed to negotiate using a special mediator, the Canadian Union of Postal Workers will be in a legal strike position as of 11:59pm Sunday, August 28, 2016.
It appears that Amazon.ca, Banana Republic Canada, chapters.indigo.ca, Gap Canada, Jysk Canada, Newegg.ca
, Old Navy Canada, Sears.ca
and Staples are still using alternatives so people using those retailers should have few issues if a strike were to happen.
