Two Ottawa sisters who gained national attention when a federal agency shut down their lemonade stand will be back in business this weekend, and they'll donate their earnings to a summer camp for children with cancer.

The National Capital Commission issued a special permit on Wednesday to seven-year-old Eliza and five-year-old Adela Andrews, with the condition that the girls donate all their earnings this Sunday to charity.

The family said they'd already decided to turn the pint-sized business venture into a fundraiser in response to an outpouring of support after the NCC shuttered the stand last weekend.

The permit issued Wednesday comes with a long list of conditions, including "that 100% of all revenue on Sunday, July 10th, 2016 will be devoted to Camp Quality ... and a portion of the revenue from subsequent days will be donated to a charity of the proponent's choice."

Business, life lessons

After the NCC shut the stand down and their story gained national attention, the family received several offers to cover the cost of camp.

The girls' father, Kurtis Andrews, said he turned down the offers because the family can afford to pay for camp. Andrews said he just wanted his daughters to learn that everything in life isn't free, and that they can achieve their goals — and a few dollars — through hard work.

Camp Quality is a non-profit organization that offers free, week-long camping experiences to children with cancer and their families.

Andrews said it's still important that the girls be allowed to run their stand as a business on subsequent Sundays.

"I want my girls to be able to make money they can keep and use for their own desires," said Andrews.

Some conditions apply

"Mr. Andrews has confirmed that he and his daughters wish to use the opportunity this Sunday to raise money for a very good cause," wrote NCC spokesman Jean Wolff in a statement to CBC News.

"The NCC has been working to foster greater animation on our land and as part of these ongoing efforts we will be reviewing our processes to facilitate philanthropic and other youth entrepreneurship activities going forward," added Wolff.​

According to the special permit, the sisters will be allowed to operate their lemonade stand during Sunday Bikedays at an assigned spot on a grassy median along Colonel By Drive, between Clegg Street and Mutchmor Road.

They'll be required to carry a copy of the permit at all times while on NCC lands and "produce it on request" to avoid further complications, according to the conditions. Any signage — including, presumably, the hand-drawn "Lemonade" sign that currently adorns the stand — must be "in both official languages, English and French of equal prominence."
