Ontario Premier Dalton McGuinty says school boards with money-losing cafeterias will have to get more creative to ensure that they stay financially viable.

The Toronto District School Board says its cafeterias face a $700,000 loss this year. Officials said Monday it is looking at shutting down some of the unprofitable cafeterias to help make up a projected budget shortfall of $58 million.

There are concerns that those cafeterias aren't making enough money due to new healthy food guidelines imposed by the provincial government.

But McGuinty defended the healthy food guidelines at a Tuesday morning news conference.

"We put a man on the moon 40 years ago. Don't tell me that we can't make healthy, delicious, tasty, attractive food for teenagers in the province of Ontario in 2012," he told reporters.

Some students say they want their junk food back.

Students in Brampton, Ont., are fighting to bring pizza, coffee and chocolate bars back to their cafeteria. A pair of students at St. Thomas Aquinas school have uploaded a popular video to YouTube calling for more junk food options.
