Deletion of 900 de Maisonneuve West

Comment: per nom. Proposed but as-yet-unbuilt buildings ''can'' pass our notability rules ''if'' they're actually the subject of substantial coverage in |reliable sources, but this appears not to be (and, for that matter, even ''built'' buildings can fail to pass our notability rules if they're not — we most certainly do ''not'' have any rule that every building in existence automatically gets an article just because it exists.) In addition, while I suppose I might be confusing it with a ''different'' proposed but as yet unbuilt office tower on de Maisonneuve, I actually have a nagging suspicion that we've seen and deleted this before under a different article title
