First responders are on scene of what could be a multiple casualty bus rollover on the Columbia Icefield in Alberta's Jasper National Park.
Tanya Otis with Pursuit, a company that runs sight-seeing tours of the Athabasca Glacier, said at 2:09 p.m. MT Saturday one of its Ice Explorer off-road buses overturned en route to the glacier.
"We will provide additional details as they become available," Otis said. "Our immediate concern is with the injured and their families and we are supporting the efforts of first responders."
The buses can fit up to 56 passengers, according to the company's website.
RCMP confirmed its Jasper detachment and other detachments were on scene of a bus rollover in the area along Highway 93 in an emailed statement.
It's believed at least 15 people were on board the bus, RCMP said.
An Alberta Health Services spokesperson said there were multiple patients, including several in critical and serious condition, and that several Alberta hospitals were being prepared to receive patients.
Police said officers were working with numerous fire departments, paramedics, STARS air ambulance and Parks Canada.

Photos posted to social media show the red and white bus flipped onto its roof on a rocky slope near the Athabasca Glacier, which is one of the toes of the Columbia Icefield.
The sightseeing buses, large all-terrain vehicles, offer visitors the chance to walk on the glacier itself.
STARS confirmed three helicopters from Calgary, Edmonton and Grande Prairie are all responding to what a spokesperson said could be a multiple casualty incident.
Police are asking people to avoid the area as emergency responders clear access to the rollover site, and said as the investigation is in its early stages updates will be provided as they become available.
Alberta Health Minister Tyler Shandro tweeted that he was heartbroken to hear about the rollover.
"My thoughts and prayers are with all those involved. Thank you to all of the first responders, EMS, physicians, nurses, and all front-line staff involved," he wrote.
