A six-year-old Toronto girl’s charity lemonade stand captured the attention of some high-profile patrons on Sunday afternoon.

Six-year-old Na’Ama Uzan was selling lemonade on John Street Sunday to raise money to find a cure for her older brother’s rare genetic condition when ‘Suicide Squad’ stars Margot Robbie and Jai Courtney paid her a visit.

“We heard about Na’Ama’s story and what she was doing for her brother Nadav and I just think it’s so inspiring,” Courtney told CTV News.

“It just shows that there’s there is no act too small when you are talking about making a difference.”

Na’Ama’s brother suffers from Angelman Syndrome, a condition that affects speech, mobility and can cause frequent seizures.

Since she started her lemonade stand a year and a half ago, Na’Ama has raised more than $60,000 for the Foundation for Angelman Syndrome Therapeutics.

“I used to do old little stands like this when I was little and I’d just spend the profits on lollies at the corner store so I’m glad she is doing something far more noble with the cause,” Robbie told CTV.

When asked why she decided to raise money for the condition, Na’Ama replied, “Because then all the Angelman kids will be able to talk, not have seizures and epilepsy.”

Approximately one in 15,000 children are affected by the disorder.

“Everything is just day-to-day, getting a little bit better one step at a time,” Na'Ama's mother Ru Uzan said of seven-year-old Nadav.

“Each little step is so meaningful to his daily life.”
