你说的香港大学是指港大还是香港的大学？你的绩点可以申请香港的大学的博士学位了~而且你在加拿大读过硕士，应该是不需要雅思或是托福成绩了，只要向学校说明你在外国读过硕士并拿到了636f7079e79fa5e9819331333332396163学位证书，学校是会免托福的。因为不知道你具体要申的学校，我就去港大查了一下申博的要求，下面是需要准备的材料：

1. Certificates and complete transcripts of undergraduate and postgraduate studies2.Statement of research interest or research proposal 3.Two academic referee's reports4.Official score report of one of the following English language proficiency tests（IBT 80 ；IELTS 6.0）(你可以不用管这个了。。)5.Official score report of the GMAT or GRE (taken within a five-year period)6.Other documents （e.g. list of publications, documentary evidence of academic awards received and professional qualifications, and summary of relevant experience.）流程就是先填网申，提交之后寄材料过去，之后就查邮箱等结果。。希望能帮到你~~ ^ ^
