Every Sunday afternoon there is a national call-in radio show on CBC called "Cross-Country Checkup", and the donating to Pakistan was the topic.

One young woman, a Pakistani-Canadian, said that so many people in her home country don't trust the government at all. However, she and some friends contacted family and friends in Pakistan, and after verifying that these people there could actually get to the disaster areas, they are channeling their money to those individuals. Then these people in Pakistan buy the supplies and take them directly to where they are needed.

Also, there are NGOs like Doctors Without Borders and the Red Cross...hopefully not having to deal with the government!

For those who wish, the show can be heard via MP3, podcast, or right on the site:
