Eligible Canadian doctoral-granting institutions
Talentrah lists the facts of this programme with attribution. The official page above is always the authority on current terms and deadlines.
Successor to the discontinued Vanier CGS. Applicant must already be "an international student registered in a doctoral program of study at an eligible Canadian institution at the time of application" — i.e. this funds international PhD students already enrolled in Canada, not a route to apply from Nigeria for a fresh admission. No nationality restriction beyond that. $40,000/year for up to 36 months ($120,000 total); page does not state a tuition waiver.
A free account also lets Farah check your eligibility and draft your personal statement, each for a small number of credits.
