What is your GPA? If it is above 80, you can come. The EE in carleton does not has many chinese as before. no more than 1/3 this year. And your classmates won't be at a low level.
Most of my classmates come form Qinghua, SHJT, As for the students not graduated form
Top 10, they have a extremly high GPA and master degree already in China. As for ranking,
there is no big difference among canadian schools. Actually you are lucky if you can get the offer. Last yaer there are more than 5000 applicants competeing for 100 master and Ph.D
admissions. If you are satified with your professor, don't worry too much about the ranking!
Carleton is very tough in getting good marks on your courses. It is natural that there will
only be 1-2 A+ in your class, sometimes, no A+ at all. It is good university for doing
reserach. BTW, You will be evaluated as how much paper you published, not where you
graduate as a student at graduate level. Your accomplishment is up to you own effort.
Good luck!
