我不知道你申请哪个专业，就拿计算机系举例吧（这是卡尔加里大学英语成绩要求比较高的系）。这是他的入学英语要求，从下面可以看出托福雅思以及GRE他们都接受，但是并没有说必须要求哪一个，纵览所有系的语言要求都与此类似，所以要是我就考雅思，毕竟容易，但是mba必须考GMAT，其他不行。
Official TOEFL/IELTS/GRE scores. To demonstrate proficiency in the English language, the Test of English as a Foreign Language (TOEFL) is required for applicants whose native language is not English. The Department usually requires an official score of at least 600 (250 on the computer-based test, 100 on the internet-based test) in order to secure admission and financial support. When submitting an application, official scores must be sent directly from the testing institution and can only be reported for a period of two years from the testing date. We will also accept an IELTS score of 7.5.
Note: Applicants who have resided in Canada (or another English-speaking country) for at least five consecutive years prior to applying to The University of Calgary, or those completing a Bachelor's degree at a university located in an English-speaking country, may apply for exemption from the TOEFL requirement. In order to evaluate applicants from different backgrounds according to a uniform standard, overseas applicants are strongly encouraged to take the Graduate Records Examination (GRE) general test.
