A lottery that supports three Alberta children's charities is facing financial losses this year.

The 4Kids Provincial Lottery raises money for Big Brothers Big Sisters in Edmonton and Calgary, as well as the Children's Cottage Society of Calgary.

The grand prize draw is Nov. 5, but only 57 per cent of the tickets have been sold. Organizers say they need to sell 62 per cent just to break even, and more if they hope to provide funding to the charities they support.

"Right now, we're at roughly $210,000 behind our break-even point," said Big Brothers Big Sister spokeswoman Lana Tordoff.

"This lottery can generate anywhere between $30,000 and $100,000 per partner, per occasion, so, you know, obviously we're hoping for the best but planning for this situation."

Tordoff estimates the lottery will finish at about $18,000 below its break-even point.

"It will certainly be felt and typically what we see is that it just prevents us from future planning," she said.

"So, expanding different programs, building our staffing to support additional programs — these are all things that we have to reconsider in terms of what the costs are and where we can find funding."

Over the past 16 years, Tordoff said, the lottery has raised $4.5 million.

However, she said ticket sales have dropped in recent years due to a number of factors, including the economy, the lottery's recent rebranding and a restructuring of the lottery prizes.

The last day to buy tickets is Oct. 22.
