> "Prices were collected from the operator with the largest marketshare in the country, using the least expensive plan with a (minimum) data allowance of 500 MB over (a minimum of) 30 days. Prices include taxes. Because these numbers are based on the least expensive plan, they are best case scenarios."
I disagree that it is necessarily the "best case" but it is a sensible way to count. Depending on the specific offering you may get unexpected results. For example, the 500MB plan may be barely cheaper than a 10GB plan, which can make sense if with that 500MB you are mostly paying for phone calls and SMS. Heavy internet users will most likely pick a plan with much more data that will be more expensive per month, but way cheaper per byte.
Also, it is split into two section: prepaid and postpaid, and Canada is at $0.07 postpaid. They just picked the highest number on the list.
