Since as stated in the hadith – cited earlier – the main purpose of Zakat al-Fitr is to feed the poor, it cannot be given to an organization.
However, one may entrust the amount to a legitimate organization authorizing them to distribute it among the needy people.
Islamic Relief Canada and Human concern international are two responsible organizations in Canada we can recommend in this regard.
I am sure there are other organizations in your country who have gained the trust of people. You may entrust them with the amount for distribution as long as you stipulate the fact that it is Zakat al-Fitr.
Almighty Allah knows best.
