我是东北财经大四的学生，现在想申请加拿大的研究生

来得及.
四years 平均分在八十,you could apply for U of Toronro, York U, U of Waterloo, U of Ottawa, U of saskatoon, U of G, U of Macmaster, Q ueen's U...... almost all of them . Make sure apply before dead line.语言考试 could take later, but you must tell them that you need to wait for the score of 语言考试.
some majores just need 75 or more, so 80 will be OK.
Do not try to apply for hot major!!!

by the way, they will consider your University in China. IF it is a key school, your 80 is 80. if not,your 80 might be 75 or 70.

Remember, pay the application fees before deadline!!!!! or you will miss it.

加拿大是承认中国大学的学历和学位的，所以你的成绩有一定参考价值。但是重要的还是你的雅思或者G的成绩，和你的科研成果，说什么也要搞一点出来。

另外，你要分清学校，这里是中国承认的加拿大大学，68所：http://bbs.redtea.com.cn/cgi-bin/bbs/topic.cgi?forum=26&topic=932

最后，去加拿大的费用，可以说是海外留学最贵的，要有家底才能去哦。
