With how stupid the CRTC is acting, You need Canada Post. They are that fastest, cheapest way to move large amounts of data across the country.
Since finding out my ISP has said they will start injecting advertising in the browser, I have been using Canada Post for out-of-band communication. Since I have a bad habit of reading fine print, I can't use any electronic transactions except Bitcoin for ordering things over the Internet (so use mail for that too).
what kind of ISP injects ads? If this happened to me, I'll switch to another service, or tunnel all my connections via ssh to a remote shell.
