Another photo showed the store's structure slumped on the ground.
In a statement, Igloolik Mayor Merlyn Recinos assured the community it would not run out of food. He said the town's only other grocery store, the Northern Store, would bring in extra product.
"Orders will be bulked up to ensure the community has enough," Recinos said. "Our community is now under a state of emergency.
"Please don't panic."
Recinos said airlines have agreed to give priority to food bound for Igloolik. Prices will be frozen at the Northern Store and flyers with coupons will be distributed to the community, he said.
