Deferment concerns

[binaryco]

I've been accepted to the program of my choice (U Waterloo). I had to defer my admissions due to family finances, but I'd be able to attend school within a year. I sent an email to my advisers & to admissions but I haven't received a response. Should I be able to defer my admissions a year? I received an RA-ship as well, so i'm not sure how it will affect funding. Within that year I'd work at a job similar to my field of interest, but attending graduate school is more important to me. I made that pretty clear in my request.
