It looks obvious

While the Canadian do not consider Freedom of speech as protected right they ruled that obese have a right to two airline seats for the price of one:

Obese people have the right to two seats for the price of one on flights within Canada, the Supreme Court of Canada ruled on Thursday.

The high court declined to hear an appeal by Canadian airlines of a decision by the Canadian Transportation Agency that people who are “functionally disabled by obesity” deserve to have two seats for one fare.

I always preferred to identify right as something that one has naturally and can be artificially abused: life, thinking (and as a results speech) or the fruits of one labor. Restrictions on one’s rights are sometimes justified but this does not change the nature of that right. While the canadian approach establish one’s rights on the expense of someone else - the “right” for two seats for the price of one would cost other passenger to pay more for no real reason.
