My first thought is that the author sounded more like a political reporter, rather than a defence reporter. One of the red flags being the notion of Canada purchasing Constellation-class frigates from the US, since that is not an option at present, as US yard are occupied filling orders for the US. Another is he seems unaware of the very different displacements intended for the two vessels, with the CSC having the greater displacement. He also seems to either be ignorant or unaware of the intention that the CSC will have both CMS330 and Aegis.
When all that gets put together, it suggests to me that the author is writing about a subject on which he has an opinion, but does not actually know what he is writing about.
