Looks great to me. Saw everybody on twitter shitting themselves over it though. As if spending Ontario transit funding outside of Toronto is such a crime.
Toronto-quebec would make a lot of sense too, but then there wouldn't be the theoretical USA connection. It's also a longer distance, and less urban areas in between (this is basically hopping from one close city to another, esp, stage one). Going to ottawa-montreal-quebec or something would involve tons of rural track, and it seems densification is the current major target of a lot of this.
Theres also this latest narrative about the "Toronto-waterloo tech corridor" which really seems to me more like two seperate tech centres that sound nicer when they're lumped together into a "corridor." It would make sense if this is their vision to have better service between the two. As it stands, transit to Ottawa & Montreal (which is WAY further, I might add) has better service than southwest to KW, London, and Detroit/USA.
