Montreal’s Canadian Centre for Architecture, the only museum of its kind in the world, is celebrating its 40th  anniversary in style.

“It’s an exhibition about happiness and looks. It’s actually critical of this constant desire of happiness,” said chief curator Giovanni Borasi.

The museum is unique in its devotion to examining humanity’s relationship with the environments we build for ourselves.

“People don’t seem to appreciate it, that’s one of the reasons why it’s important to have the CCA,” said founder Phyllis Lambert.
