It would very rarely, if ever, contain one. I certainly can't recall ever having seen one with a section 1 analysis.
The reason is that, when you get into a section 1 analysis, you're balancing the actual provisions in an act with a section of the charter, and you're asking whether it's potentially justified as a limit that is reasonably and demonstratively justified in a free and democratic society.
That's something that puts you in the realm of doing a political analysis or giving an actual legal opinion, which, for either case, would not be something that would be in the neutral framework of a charter statement.
I personally think I would never see one, as I can't recall ever having seen one. Section 1 implications do not have their place in the charter statement, the goal of which, as I've already set out, is to articulate the articles under the charter that might be impugned by a potential piece of legislation and the considerations that are there that explain the law.
