Can the embassy in Ottawa authenticate a Malawian birth certificate?

I have to have my two children's birth certificates notarized/authenticated by the embassy in Ottawa. My son was born in Canada, but my daughter was born in Malawi. Her birth certificate is Malawian. Can the embassy authenticate a Malawian birth certificate? I have had both the birth certificates notarized by a lawyer here in Halifax, N.S. I will then be sending them via courier to an organization in Ottawa, called, 'Golden Mile 2000 Travel Consultancy,' which will bring documents to the embassy on my behalf.
