This just baseless conjecture, and even somewhat conspiracy-theory adjacent, but my best guess is one of the Irving families' companies is somehow involved here.
The Irving's, if you don't know, are one of the richest families in Canada, and effectively own the province of New Brunswick and run it like their own personal fiefdom. They are also heavily connected to both the Federal and Provincial conservative parties (And the Liberals too honestly), so I would assuage a guess that they had something to do with squashing the former investigation as they knew they were somehow culpable and used their cronies in the government to protect them from any potential liability.
Again, this is all just baseless conjecture, but it feels like at least a potentially reasonable explanation here, as it would be far from the first time billionaires used their wealth and political connections to kill an investigation into their own malfeasance.
