Aid groups are warning people to be careful about giving money to lesser-known organizations collecting donations for the typhoon relief effort in the Philippines.

Some groups are just scam artists while others — despite good intentions — could create more problems on the ground, said Calgary Chamber of Voluntary Organizations president Katherine Van Kooy.

“They're not necessarily well equipped to undertake the work. They put a real strain on the infrastructure within the country which is already stressed,” she said.

Donors should make sure any charity they support has a registration number and the canvasser is able to provide information on exactly how the money will get to those in need, Van Kooy said.

Calgary's Filipino community is planning a telethon to raise money for victims of Typhoon Haiyan.

Project Pagbangon which means Filipinos Rising Up — will be held on Dec. 1 but donations are already being accepted at Pacific Place Mall at 999 36th Street N.E.

The official death toll from the massive storm now stands at 2,344.

An estimated 600,000 people are displaced and there are reports that parts of the disaster zone are descending into chaos as desperation for food and water grows.
