I think Cobourg definitely wins the "punching above its weight" award for this thread - what a gorgeous building!
Here's a full picture of our current (1970-) City Hall in Saint John:

Cheapo modernism at its finest, but I can't imagine the Uptown without it. Notably, the Council Chamber (black box with the coloured fingers at the base of the tower) was recently painted white... for some reason.

The building, which the City actually leases rather than owns outright, has a pretty high vacancy rate at the moment - the Police HQ and a couple provincial courtrooms have decamped to new digs up the hill at Peel Plaza, and the BMO branch on the ground floor recently moved across King Street to CenterBeam Place.
There's been some back-and-forth between the City and the landlord about consolidating remaining municipal office space (whose current distribution resembles that of a fragmented disk) in the lower floors of the tower, which would allow the upper floors to be renovated as a block for commercial tenants, but nothing firm has materialized on that front yet. Every so often the idea of moving out entirely (to new and/or renovated space elsewhere in the Uptown) crops up in Council, but I don't think the public or political will to stomach such a capital outlay is there at the moment.
