Wow, the same happened to me too. Got a 10.61 (10th ranked app), but I'm a first year in the states. I was pretty stressed they were going to take the whole funding away/this was a mistake, but maybe they'll just swap out the 35k for the 20k and we'll be okay? It's a terrible exchange rate so it's not even that much money haha.
Does anyone know what happens to student funding packages if they're international when they get SSHRC? 15k USD isn't replacing my current package obviously, but I'm not sure if theres a clawback policy like with a bunch of US fellowships.
