This kinda blew my mind (in a good way) and I think you should know:

Every dollar given to an organization like the Red Cross or Direct Relief International provides up to $30 of (wholesale) medical material aid.

Which means, no amount is too small. Right?

Donation advice for Canadians:

How can I donate wisely and avoid fraud?

Confirm that the organization is a Canadian registered charity or a qualified donee.
If you would like an official donation receipt, remember that donations have to be made to Canadian registered charities or other qualified donees in order to claim a tax credit. To confirm that an organization is a Canadian registered charity, go to the CRA Charities Listings.

Get to know the charity.
Start by visiting the charity’s Web site to learn about its activities and how it’s managed. You can also review its financial information and activities by looking at its Registered Charity Information Return on the Charities Listings. One of the best ways to learn about a charity is to volunteer.

Beware of donation schemes that promise you returns greater than your donation.
The CRA strongly advises that you not participate in donation schemes or illegal tax filings.

Learn to recognize the signs of fraud.
Start by testing your knowledge by visiting the ABCs of Fraud and review our list of common Warning sign of fraudulent activities.

Take action
Write cheques payable to the charity, not an individual, or make sure that your online payments are secure.

Refuse to donate if there is inappropriate pressure to give immediately, or if there are signs of fraud.
