Yes, we have seen some shortages on grocery store shelves, but professors Michael von Massow and Alfons Weersink of the University of Guelph explain why system will catch up.

'There's such a demand right now, people baking at home, that stores just can't keep it on the shelves.'

Through unprecedented times of stress like the COVID-19 pandemic, some have resorted to panic buying. But liquor and cannabis stores in Lethbridge haven't reported any.

While sales have been exceptional this week, the store owner is predicting a downturn that could last a while.

The video comes as the COVID-19 pandemic has caused shoppers to stock up on food and toiletries, especially toilet paper.

The last few weeks have seen Canadians emptying the shelves at grocery stores in response to the coronavirus pandemic. Is it necessary? Will there be food shortages? Experts say no.

"They were laughing and being quite boastful about filling up the carts and having everything."

A clinical psychologist who specializes in the psychology of pandemics says buying and hoarding items in bulk quantities can actually help spread the disease.

"Rest assured, we have plenty of food that will continue to reach grocery stores on a regular basis," Ontario's health and agriculture ministers said Saturday.

This buying comes after posts on social media showed empty shelves. But experts say stocking up isn't necessary.
