It's busier than Boxing Day at stores that sell school supplies.
Thousands of parents head out following their children's first day of school to fill their kids' check lists.
At Staples, it's called "Super Tuesday" a time of the year during which sales more than double, according to president Steve Matyas.
"If you would take 100 per cent of your sales and divide it up by 12 months it works out to roughly about 8 per cent of sales on a monthly basis," he said. "At this critical time of year for us, sales are in excess of 16 per cent of our total volume."
He said top sellers are loose-leaf paper, bold-coloured back packs and tablets.
"Tablets are making their way into the school system at lower and lower grades," he said. "We were seeing them, needless to say, in the post-secondary area, but we're also seeing them in high school kids and now we're seeing them in the higher grades, like grades 7 and 8."
