The group are presented with their oversized check for $60 million - $5 million each.

A group of 12 workers in Markham, Ontario erupted into a frenzy after learning they had won Friday 1 October record-high Lotto Max jackpot of $60 million.

The winners are employees of Canadian Black Book, a company that publishes resale information about used cars. They all participated in a group play run by their colleague, Dennis Cartier.

The win was big news because of its jackpot size.

Cartier said he didn't find out about the big win until he checked the numbers on Saturday afternoon while on his way to pick up lunch.

The winning ticket was purchased at this Petro-Canada gas station on Kennedy Road in Brampton.

He checked his ticket at a gas station and couldn't believe his eyes. He then raced home, signed the ticket and put it on the refrigerator.

Dennis Cartier (center) explains how he dealt with telling the rest about the win.

"I wanted to stay calm, eat my burrito and check the numbers again online. Every single number matched up, so I went back to where I bought the ticket and that's when it all became very real."

Cartier, who was not supposed to work Monday, arrived at the office in sandals and a T-shirt instead of his usual suit. He called a work meeting and broke the news.
