I'm not really sure what we're supposed to get out of this. Based off the wording of the article, it seems like many of the things that the Federal Government want is simply infeasible with any rerouting that doesn't fundamentally alter what this highway even is. An example the article uses is the Western Chorus Frog, and the article quite literally states that "Highway 413 would run across Ontario’s largest remaining patch of habitat vital to the western chorus frog’s survival in the province, destroying an area equivalent to about 30 soccer fields. The federal government
warned Ontario in 2023 that minor shifts in the highway’s route would be unlikely to help, as the frog can be impacted by highways up to 2.4 kilometres away". In other words, there is no routing that solves this issue. Its not like the story is that the Federal Government proposed an alternate alignment that would help mitigate some of these environmental concerns and Ford refuses to budge - the story very much seems to be that the Feds are putting the onus on the province to find a way to build this highway without those concerns, and that in practice the only way to do so would be to just not build the highway (which obviously isn't going to happen).
