A Winnipeg girl is hoping to make Halloween a little sweeter for families as she collects costumes for kids who canā€™t afford them.

Callie Costello, 12, is asking Winnipeggers to donate their lightly used Halloween costumes so that no trick-or-treater gets left behind come October 31.

With the help of her mom, Crystal Costello, Callie has set up about 20 drop-off locations across town for her drive.

ā€œItā€™s Halloween and thereā€™s a lot of people who donā€™t have Halloween costumes, and thatā€™s really, really sad, because ā€¦ Halloween is about kids,ā€ Callie Costello told Ā鶹“«Ć½.

Her mission is simple: ā€œA lot of costumes. Thatā€™s my goal,ā€ she said.

Callieā€™s efforts help shed light on the state of child poverty in Manitoba, where, in 2012, nearly 30 per cent of children lived below the poverty, according to a 2014 report by the Social Planning Council of Winnipeg.

Those figures mean that, come Halloween, plenty of kids simply canā€™t participate, one expert says.

ā€œI think we have to remember that many children in Winnipeg and Manitoba are experiencing poverty, and that prevents a lot of kids from taking part in these larger societal experiences,ā€ said Michael Champagne, founder of Aboriginal Youth Opportunities, an organization that helps First Nations youth.

Itā€™s not the first time Callie has committed to helping others. In 2013 she started ā€œCallieā€™s Backpacks,ā€ a campaign to collect backpacks filled with snacks, toiletries and water for the homeless. In just six months Callie had backpacks for 185 people, and she continues to collect donations today.

ā€œIt makes me feel good to help people,ā€ she said.
