The Bal en Blanc -- the popular, annual rave party in Montreal -- wrapped up at noon Monday at the Palais des Congres.

There were three days and nights of smaller parties across town, but the Palais plays host to the main event.

White is de rigueur

About 15,000 people, decked out in white attire, attended the party.

Ravers had their choice between one room dedicated to techno music and another featuring house music.

Only one arrest this year

In the past, the rave has been marked by drug-related arrests.

However, this year, only one person was arrested by Montreal police.

Thirteen people were arrested last year.
