Your objection is just semantics.  The Supreme Court ruled that criminalizing abortion or excessive bureaucratic restrictions to accessing abortion is inconsistent with the specific Charter rights of conscience and security of the person, ie, women have a right to abortion because they have Charter rights.

I think the G&M is wrong to frame this as merely an ideological difference.  The issue is not whether Harder calls herself a feminist, nor whether she would personally choose to have an abortion.  It's ultimately about whether or not she endorses women having Charter rights.
