About going to Canada to study for a PhD.

As far as language test standards are concerned, both master's and doctoral courses in Canada recognize IELTS or TOEFL; Many universities require GRE scores for master's and doctoral majors in biological sciences. Even though some universities say that GRE is not necessary, if you have a good GRE score, your admission chances and scholarships will be improved, so I suggest you don't steal this laziness and study hard for GRE.

You don't have to worry about the doctor's financial aid. There is no difficulty in applying for grants for doctoral studies in Canada and the United States. Research doctoral students in Canada and the United States are guaranteed full grants, which are enough to cover their living expenses and tuition fees, to ensure that they concentrate on their research, and students do not have to spend extra money and have no financial burden.

However, in the graduate school system in Canada, scholarships and grants are not the same thing, but some people like to confuse them. Scholarships will only be awarded to outstanding master's and doctoral applicants (generally, 60% master's and doctoral students can't get scholarships), which is competitive. If you can get a scholarship, you will get more money and live a more comfortable life. As for the master's and doctoral students who can't get scholarships, don't worry, because the graduate school and your tutor will give you money through bursury grants and the remuneration of teaching assistants and research assistants, which is enough for you to pay for living expenses and tuition fees.

Your undergraduate and postgraduate grades, as well as your thesis level during the postgraduate period, as well as your IELTS and GRE scores, are very important for your doctoral application, and it is also very important to communicate with your potential tutors. If your potential mentor approves of you, you will succeed more than half.

Canadian universities, such as the University of Toronto, McGill University, UBC University, etc. Both of them are very strong in biological sciences and require GRE, so I suggest you don't steal this laziness, study hard and get a good GRE.

Good luck.
