UK tier 4 visa: Language test

K

Hi, I have received a PhD offer from a UK university. Since I do have my MSc from a Canadian university (but I am not canadian), the conditional offer letter does not ask me to provide any english language test. Now, does the visa application requires any language test?
As I look into the visa requirements, it seems that they excluded Canada from the list of exempted countries:

Please advice.
Thank you.
