However, Applicants are not required to submit GRE scores. Hence GPA and TOEFL are the major effective factor for your application, if you do not have strong research background. At this point, I do not think 590 is enough. Anyway, if you have high GRE(though not reqiured, you still can submit it), or high GPA like 3.7+, or strong research background, you could use this TOEFL to try.
BTW: as lots of EE apply mainly for us univs, they also apply for can univs as back-up. resently, canada univs EE is even more difficult to get AD or Offer.
