Police will not be laying charges in a bus crash that killed 17 people in western Manitoba.

RCMP say they do not expect to be able to talk to the bus driver, who was severely injured in the crash.

Canada's population of those 85 and older is expected to triple by 2073 to as many as 4.3 million people, an increase that will likely place new pressure on the country on several fronts, one demographer says.

Statistics Canada said in its projections released Monday that the country's population could reach a medium-growth forecast of 63 million by 2073 and at least 3.3 million will be over 85. 

The agency said the aging population and low birthrates mean that migration will be the key driver of Canada's growth for the foreseeable future.

Alberta is moving to ban cellphones in kindergarten to Grade 12 classrooms starting in the fall.

Alberta Education Minister Demetrios Nicolaides said Monday that cellphones help with learning but can also be a distraction and lead to cyberbullying.

He said there will be exceptions for students who use phones for health needs, such as monitoring blood sugar levels.

Otherwise, personal devices must be turned off and stored out of sight during class time. School internet networks will also have to limit access to social media, Nicolaides said.
