The definition of equality under the charter is a definition that has been developed through case law, and it's a term of art. When you say “equality”, you don't mean formal equality, you mean substantive equality, and that has a meaning. It has content.
Historical injustice is not a legal term of art. You could use it to describe anything that you deem to be a historical injustice, but I think what Minister Goodale was doing in his testimony was being very careful, because the government in essence has created it to be a term of art because of the way that it has structured Bill C-66. I think Bill C-66 was designed to address it with the term “historical injustice”. There was a schedule, and on that schedule they put offences they deemed to be historical injustices. In order for them to have an argument to exclude certain offences from that schedule, they would have to define them as something other than historical injustices.
So I think it's a term of art that's artificially constructed, but you can define historical injustice in any way that you choose to.
