I accepted my program about a month ago and I was wondering if universities will know this and not feel incentivized to give me faculty specific scholarships? For context I accepted a Waterloo Math program and I was wondering if I then lose my chance to get the National Math Scholarships etc.

So I was just wondering if anyone was able to get scholarships that didnt require an application apart from the entrance one, that accepted their program before may in previous years??
