colourful houses

we spent another day exploring Montreal.  These very colourful houses were in the Plateau Mont Royal area. We then headed on to the Mont Royal where there is a great view down onto the city. 
In the afternoon we had a look around the ICAO (international civil aviation organisation) building where our friend works. Later we were given a private tour of the Montreal Area Control Centre  which was a fascinating insight into how they control flights in what is a very busy area. as many flights between Europe and the USA will fly over it even if not landing there.  Finally a late supper and repacking as we set off again in the morning.
