A gunman opened fire on an outdoor music festival in Las Vegas, killing at least 59 people and wounding more than 500 others.

Officials say a gunman on the 32nd floor of the Mandalay Bay Hotel and Casino began shooting towards the Route 91 Harvest Festival around 10 p.m. on Sunday.

Authorities have identified the suspected gunman as Las Vegas resident Stephen Paddock.

Police allege Paddock, 64, was the “lone suspect” involved in the late-night mass shooting. Authorities say he killed himself before SWAT teams stormed his hotel room.

At least 2 Canadians are among the dead. 23 year old Jordan Mclldoon from Maple Ridge B.C.  and Jessica Klymchuk, a mother of four from Valleyview Alberta.

Country music star Jason Aldean was performing on stage to a crowd of more than 22,000 concert-goers when the shots rang out. Aldean took to social media to say he and his crew are safe and send his thoughts and prayers to those everyone involved.

Tonight has been beyond horrific. I still dont know what to say but wanted to let everyone know that Me and my Crew are safe. My Thoughts and prayers go out to everyone involved tonight. It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night. #heartbroken #stopthehate
