Do you only need a work visa to work in Madagascar?

I'm a 16 year old (17 in April) Girl who is living in Canada. In 2021, I plan to move and permanently live in Madagascar. When I want to work in Madagascar, in order to immediately get a job (like a 1-2 weeks), do I only need a work visa to get a job. BTW, I'm a Canadian citizen of Nigerian descent.

Rules can change from year to year and certainly some changes will be made by 2021.

The immigrant visa is valid for one month. It is convertible into a long stay and is intended for investors, expatriate workers, trainees, travelers on mission, pensioners and family reunification candidates. It can be transformed into a long stay within one month of entering Madagascar.
