Quebec Municipal Elections 2017

[MaxQue]

I'm somewhat confused by the numbers:
https://en.wikipedia.org/wiki/Montreal_municipal_election,_2017

If you count, Borough Mayors, City and Borough Councillors its (from wiki above):
PM - 49
eDC - 39
eBarbe - 7
eAnjou - 5
CM - 1

Any reason why the count isn't shown like that?

Also, interesting physical divide on the map here on La Presse
http://www.lapresse.ca/multimedias/201711/03/01-5142260-resultats-des-elections-municipales-2017.php if you look at the results for mayor, Coderre won the Boroughs along the north side of the City (except L'Ile-Bizard), Plante won those along the south.

Borough councillors don't sit on the City Council.

I'm sure I'll regret asking, but what is a borough mayor?  The idea of having an overall mayor and a bunch of little area mayors sounds insane.

Most merged cities have them, it's just than the other cities have the borough council elect it from their own members.

It's a two layers system.
City: Montreal mayor + borough mayors + city councillors. It manages city-wide issues

Borough: Borough mayor (Ville-Marie borough mayor is Montreal mayor) + city councillors from the borough (some small boroughs have no city councillors as they are entitled one seat in City Council, so only the borough mayor sits on City Council) + borough councillors (for small boroughs, so there is more than 2 or 3 members on it). It manages proximity issues.

It's quite a decentralised system. I think it's more democratic than most cities (i.e. Etobicoke forcing Rob Ford on central Toronto).

Équipe Denis Coderre already lost a member, the Verdun borough mayor is becoming an independent, in order to be nominated on the Executive.
