The requirement is a level 4, but when you get to the permanent residence application process, it's a level 5. For certain work, maybe that is even too high a level. This is not to say that a person should not speak English. Of course they should, to a certain degree. What level do you think should be required? Is it a level 4 or a level 5 in both written and verbal?
