Over 15,000 partygoers dressed in white are slowly leaving Montreal's Palais des congrès this morning as the 19th edition of Bal en Blanc wraps up.
French DJ superstar David Guetta made his fourth appearance at the all-night dance party, which is held on Easter weekend every year.
The event started at 9 p.m. last night and goes until noon today.
Spokesman Paul Gilbert estimates between 20 and 25 per cent of revelers come from outside Quebec, resulting in $500,000 in tourism dollars.
The visual concept was dreamed up by Moment Factory, a Montreal company that is known for its work with Cirque du Soleil, Céline Dion and Madonna.
