Unfortunately I don't see anything in the documentation that explains why Canada's international parcel rates are at least double any other country. If you know the relevant sections, please let me know.
The damage from unions is from many years of abuse, and there is no question that union wages have hurt us in the long run in many industries. Unfortunately unions are no longer being used as intended, and despite union propaganda, serve more to protect bad workers than they do protect the good from bad employers.
Canada Post is a crown corporation, of course it's all about politics, that's why it's just another CC in trouble. Once you embed a union, there is no victory to be had and the damage is done. That's why companies like Couche-Tard do what they did... they tried to set up a union in about a dozen locations, Couche-Tard (a corner store chain) shut down all 12 locations overnight.
Anyhow, CP will never have any sympathy from me and their ridiculous fees and I like thousands of other shipping companies will refuse to work with them when there are so many cheaper alternatives for parcel service.
