Deletion of 2016 Ottawa sinkhole

Comment: Nothing about this is so independently notable in its own right as to require a ''standalone'' article as a ''separate'' topic from its natural parents. It should certainly be mentioned in Rideau Street and Confederation Line as an ''aspect'' of those topics, and I'm torn as to which one should be the primary redirect target for the title (if we even keep a redirect at all) the title should be kept as a redirect to Confederation Line (we can then minimize duplication of content by ''briefly'' summarizing the event in Rideau Street and allowing the ''line'' article to hold the ''substance''), but this in no way needs its ''own'' article ''separately'' from the ones that already existed. If the significant effects that LeadSongDog suggests above actually do come to pass, then a new article can be created at that time — but the justification for a separate article will be ''after'' those effects have ''already'' come to pass, not right away on the basis of one user's  predictions about what ''might'' happen in the future
