I am Nasreddin Ishaq Adam from Sudan, South Darfur, Nyala, requesting emigration to Canada due to the wars and the security, health and living conditions in the country, Sudan in particular, Darfur.
These organizations are approved to sponsor refugees and you will have to contact them individually. Many are no longer accepting new sponsorship but you can certainly contact them.
The other option would be referred by UNHCR. Because Canadian government accepts those refugees that are referred by UNHCR
