Leah Miller

The Gemini Award-winning host of the smash hit So You Think You Can Dance Canada, Leah Miller, who is also a correspondent for etalk, has come a long way from the audition that landed her a job with Canada's flagship music station, MuchMusic.

As a five-time host of the MuchMusic Video Awards and former co-host of MuchOnDemand, Miller has chatted with some of the hottest celebrities around, including Lady Gaga, Halle Berry, Natalie Portman, Gwyneth Paltrow, Sarah Jessica Parker, Coldplay, Kanye West, Rihanna and Slash.

Miller was also named one of Flare's 30 most inspiring, newsworthy women to watch. As host of So You Think You Can Dance Canada, Miller leads viewers through the dancer's journey as she gets up close and personal with the competitors during the audition process and stands by their sides as they face the judges during the live shows.

With a background in dance, Miller has first-hand knowledge about the hard work and dedication it takes to become a competitive dancer, and has huge respect for dancers at the level the series demands. Miller cites family as the most important thing in her life, and if it wasn't for their support she says she wouldn't be where she is today. Family, Miller's passion for the fine arts, and her previous hosting and interviewing experience have helped her excel as host of So You Think You Can Dance Canada.

Jean-Marc Genereux

Returning as a So You Think You Can Dance Canada judge for a fourth season, Quebec's Jean Marc Genereux began dancing at age 10 with his partner, and now wife, France Mousseau. Within six years the pair had won every Regional and State Championship. In the early 1980's they began dancing the International style of ballroom dance and won multiple competitions and all the Major Championships in North America, participating in 10 World Championships as the first representatives for Canada.

Genereux and Mousseau turned professional in 1987 and danced in every major city around the world from Asia and Australia to Europe and America. In 12 years they won over 200 competitions. Genereux and Mousseau retired from the competitive scene in 1998; however, the two still travel all over the world to judge and choreograph for elite competitors.

Genereux performed in the motion picture Dance With Me, featuring Vanessa L. Williams, and the motion picture Shall We Dance, with Jennifer Lopez and Richard Gere.

In 2006, Genereux joined the cast of the American version of So You Think You Can Dance as a choreographer, and is back for the show's current season. Genereux has created choreography for The Rachel Ray Show, and more recently was a permanent judge on Dancing With the Stars France.

Genereux was also the lead choreographer for the motion picture Funkytown, and appeared in the tenth season of DEGRASSI as a dance teacher. Genereux is one of the organizers behind the Rocky Mountain Dancesport Grand Prix in Calgary, AB this coming fall, and recently started his own line of dance shoes through the company Dance Import International.

An avid artist and painter, Genereux has become well-loved by viewers as the judge who speaks from the heart and isn't afraid to show emotion, but dancers have to work hard to earn a spot on his VID (very insane dancer) list.

Luther Brown

Luther Brown is returning for the fourth season of So You Think You Can Dance Canada as judge and choreographer. Brown made his mark during Season 1 with his hard-hitting hip-hop choreography and no holds barred comments from behind the judge's desk, and continued to create memorable routines throughout the second and third seasons. His creative, trendsetting and innovative vision has transformed the formerly unknown Toronto urban dance community into a thriving industry. As the founder and owner of Do Dat Entertainment, he created a movement that linked Toronto to the ever-growing entertainment segment of the United States. As one of the most sought-out choreographers in North America today, his work has been featured in over 100 music videos for artists including Diddy, Janet Jackson, Shawn Desman, Jully Black, Cascada, Nicola Roberts and many, many more. Luther recently represented Canada as one of the judges for the World Hip-Hop Dance Championships, a yearly event in Las Vegas that is put on by one of the creators of America's Best Dance Crew, and provided principal choreography for the major motion picture Honey, featuring Jessica Alba. His unique style of "hip-hop soul" choreography has enabled him to travel around the world and teach many memorable workshops. Brown has also been fundamental in launching and developing the young careers of many new artists across Canada and the U.S., including Electrik Red, FeFe Dobson, Cory Lee and his very own artist - TRISH, who is signed to his record label - Apathamusic. No matter what the occasion, Luther is always ready to deliver memorable and extraordinary pieces of work.

Blake McGrath

Originally from Mississauga, ON, Blake McGrath returns as judge and choreographer for So You Think You Can Dance Canada Season 4. Currently residing in Los Angeles, McGrath continues to take the entertainment industry by storm.

At the age of 26, McGrath has already shared the stage with Madonna, Janet Jackson, Britney Spears, Jennifer Lopez, Beyonce, Mariah Carey and more. Best known for his memorable appearance on the first season of So You Think You Can Dance in the United States where he was a finalist, McGrath also appeared on Jennifer Lopez's TV series Dance Life.

McGrath's film credits include the Academy Award-winning film Chicago and the musical Rent, and he also has extensive commercial experience, appearing in commercials for Gap, Old Navy, Pepsi, Hummer and iPod, to name a few.

McGrath released the DVD Dance Driven, and co-owns Coastal Dance Rage, one of the world's largest dance conventions. And if that wasn't enough, McGrath released his debut album Time To Move last fall with music industry power house Universal Music Canada.

Already working on his sophomore album, Love Revolution, which is set to be released this winter, fans can stay connected with McGrath through his facebook fan page.

Tre Armstrong

Returning as a So You Think You Can Dance Canada judge for a fourth season, Tré Armstrong is looking forward to finding Canada's next favourite dancer. Armstrong's love and understanding of urban dance and hip-hop has brought out the inner teacher in the artist and has allowed her to travel the world sharing this knowledge through workshops, seminars and classes in hip-hop, urban and freestyle dance. Now, it's time to give back and Armstrong is bringing it home with her company A New Daei. Tré's competence and work ethic has made her a go-to choreographer for various artists, including Sean "Diddy" Combs, Kreesha Turner, Sarah Brightman and Jason Derulo, and she just completed choreography for Ludacris' new "Breakaway" music video. This talented artist brings not only her dance skills, but life skills, to participating youth in her workshops and seminars, firmly believing that by instilling confidence through performing arts, there is no stopping what they can accomplish. Known for her honest critiques, this judge always speaks her mind.
