EDMONTON — 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. 
 
 "My dad asked me if I wanted to sell cookies and I said yes," she said in an interview after school Thursday. "So we started selling cookies there and they sold out very quickly." 
 
 Canadian Press Nine-year-old Elina Childs poses as she sells Girl Guide Cookies outside a cannabis store in Edmonton on Wednesday. 
 
 Her father, Seann Childs, said they sold cookies going door to door in their neighbourhood last year, but people often weren't home or there would be big dogs in the yards. 
 
 "We thought, 'Where can we go to sell them?'" he said. "It just so happens that legalization was coming up in a couple of days." 
 
 When Elina got home from school Wednesday, she grabbed some change from her piggy bank. She and her dad loaded up a wagon with three cases of Girl Guide cookies and they walked a few blocks to the nearby cannabis store. 
 
 She started walking up and down the lineup. 
 
 "It was well received," said Seann Childs. 
 
 Elina said people told her "it was a smart idea and that they'd like to buy some cookies."

 Her dad said some cars even stopped on the street to buy a box. 
 
 "It was really something else," he said. "I'd never seen anything quite like that." 
 
 Childs said he expected it to go well, but he never thought she would sell out of all the cookies they had left in the three cases — about 30 boxes — in 45 minutes. 
 
 "We were sold out in no time," he said.

 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 teaching moment 
 
 A social media post on Elina outside the pot store went viral and Monahan said they started getting questions from other parents 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." 
 
 To make it even better, Elina's parents were able to use the experience as a teaching moment for their daughter. 
 
 "She actually has cystic fibrosis, so we encourage her to get out there and do things and be active," Childs said. "Girl Guides is one part of that." 
 
 He noted that smoking is usually harmful to her. 
 
 "This was one day she could benefit from smoking," said Childs. "We saw that as an opportunity to get out there and teach her a little about what cannabis is. 
 
 "Obviously she's not going to be using it before she's 18, I hope, but we like to have frank discussions with her, so she understands what it is and take away that mystery behind it — just to show her people of all ages and all walks of life are doing this and it's legal in Canada now, just demystify it for her so it's not a big deal for her." ||||| CTVNews.ca Staff 
 
 
 
 
 
 A nine-year-old Alberta girl managed to rapidly sell out of Girl Guide cookies by targeting cannabis consumers on the first day of legal sales. 
 
 Elina Childs tells CTV News Channel that it was her father’s idea to load up her wagon and line up outside of an Edmonton pot shop on Wednesday. 
 
 Elina, part of the Girl Guides Canada Brownies program, unloaded all 30 boxes of cookies at $5 each in about 45 minutes, according to her father, Seann Childs. 
 
 Childs says he came up with the idea a day or so before legalization. 
 
 “We were going to sell them in the neighbourhood and it’s always been a little slow,” he said. “Elina was actually bit by a dog once.” 
 
 “She did a fantastic job and was very polite and everyone was very polite with her,” he added. 
 
 Childs added that he used the experience to teach his daughter about legalization. 
 
 “We talked about ... what it was and what it means for people who want to use it and people who don’t want to use it,” he explained. 
 
 Childs said Elina has cystic fibrosis and the Brownies program has been important to keep her active. 
 
 He also said that smoking is normally harmful for her, so this was “the one day she could benefit from smoking.” 
 
 "We like to have frank discussions with her, so she understands what it is and take away that mystery behind it,” he said in a separate interview with The Canadian Press. “Just to show her people of all ages and all walks of life are doing this and it's legal in Canada now, just demystify it for her so it's not a big deal for her." 
 
 Elina didn’t elaborate much on her experience in her national TV interview beyond saying it was “fun.” She did, however, share a great joke. 
 
 “Why did the cookie go to the doctor?” she said. “Cause it was feeling crummy.”
– Canada is still getting the hang of this legal marijuana thing, and one 9-year-old girl seems to be ahead of the curve. Elina Childs, who belongs to the Canadian version of the Girl Scouts, called Girl Guides, set up her wagon outside an Edmonton pot store and unloaded all 30 boxes of her cookies in just 45 minutes, reports CTV News. "They sold out very quickly," she says, giving her dad credit for the idea of pitching to customers who might soon have the munchies. Elina has cystic fibrosis and cannot be around smoke, but "this was one day she could benefit from smoking," dad Seann Childs tells the Canadian Press. (After just one hour of legalization came a milestone ticket to a driver.)
