The budding entrepreneur loaded her wagon with sandwich biscuits and mint thins and within 45 minutes had sold everything, earning a tidy $120 (£70) for the Girl Guides.
A young member of Girl Guides is being praised for her entrepreneurship after selling cookies outside a cannabis store on legalization day.
On Wednesday, people across Canada celebrated the legalization of marijuana by lighting up on sidewalks and in parks.
According to an article on cbc.ca, Elina Childs has cystic fibrosis and can't be around people who are smoking, but Seann Childs said it was a good educational opportunity for Elina to learn more about marijuana.
Her father, Seann Childs, said they sold cookies going door to door in their neighbourhood a year ago, but people often weren't home or there would be big dogs in the yards.
"Everybody was respectful, everybody was happy, and she walked away from it as this incredibly positive experience as well as selling out all her Brownie cookies", he said.More news: More than 1,000 people attend Belfast anti-Brexit rally

"It amazed me how quickly they went", he told CBC.
She started walking up and down the line hawking her wares. "Even people in cars driving on the avenue there would stop and roll down their window and ask for cookies".
Elina said people told her "it was a smart idea and that they'd like to buy some cookies".
"She didn't quite understand what the big deal was", Childs said.
"It was well received", said Seann Childs.
Childs said his daughter has always had an adventurous entrepreneurial spirit.
