My friend & colleague Étienne rightfully notes that…

[If you live] in Québec, we get 35% of the first 200$ of donation to registered charity back in taxes credit, and 53% of amounts above 200$.
Yes, 53%. That basically means that the government already matches your donation by crediting you half of it. So I am going to make my donation to the Canadian Red Cross, double the amount I can afford to give, and get half of it back in taxes credit next year.

Merci pour l’explication Étienne!
