$250 000 were raised at the 7th edition of La Grande Soirée

The 7th edition of La Grande Soirée hosted at the sumptuous Windsor Ballrooms of Montréal ended on a great note with a total of $250,000 that were raised to help prevent more high school teenagers from the risks of alcohol, cannabis and other drugs consumption.

A special THANK YOU to Mr. Claude Lachance, General Director of GCA Immobilier, who was named Honorary President for a fourth year in a row and whom, once again, showed his great generosity for the cause.

Thank you to our young special guests Alfred Poirier and Émilie Claire le Ménédeu, and young professional Jean Simon Bourgie, who gave touching testimonials during the evening.

We also would like to point out the amazing generosity of our partners GCA Immobilier, Altek Windows and Doors, Contruction Vachon et fils, Canidé, Creativ Nation, Lab Cocktail Bar and Discount who helped us offer this wonderful dinner cocktail to the hundred attendees.

Finally, A HUGE THANK YOU to all the participants and volunteers who greatly contributed to this stellar evening. See you next year!

Here is the impact of your gesture

Thanks to your commitment to this evening, at the end of this school year we will have been able to prevent drug addiction with 76 000 teenagers in high schools across Quebec.

Since we have been preventing teens, we have seen a 16.5% drop in youth addiction problems.

Prevention Works!
