She's being called one smart cookie.

As people lined up to buy cannabis at one of six Edmonton cannabis stores that opened Wednesday, a small entrepreneur stood ready to capitalize on what could be expected to be customers' future need for a sweet snack.

Nine-year-old Elina Childs had a wagon full of Girl Guide cookies for sale.

"We've sold cookies in the neighbourhood before with her and it's door to door. People aren't home. There's dogs and everything else," said her father, Seann Childs. "We thought, 'Where can we go to sell them?'

"It just so happens that legalization was coming up in a couple of days."

He and his wife talked to Elina and she thought it was a good idea.

When she got home from school, she grabbed some change from her piggybank. She and her dad loaded up a wagon with three cases of Girl Guide cookies and they walked to the nearby cannabis store.

She started walking up and down the lineup.

"It was well received," said Childs. "People thought it was awesome. There were people telling her she was doing a great thing, that it was very innovative. There were cars stopping on the street to buy cookies from her. It was really something else. I'd never seen anything quite like that."

Childs said he expected it to go well, but he never thought they would sell out in 45 minutes.

An official with the Girl Guides praised Elina's strategy.

"Good on her and her family for thinking of it," said Edmonton commissioner Heather Monahan. "It's fun and it's different and what better way to get rid of cookies."

A social media post on Elina outside the pot store went viral and Monahan said they started getting questions about whether it was allowed.

"Why wouldn't it be?" she said. "It wasn't like she was in the store — that would be a whole different ball game.

"I think it's wonderful."
