Subject Tests or no??

Hi there,
Planning on applying to McGill College of Arts&Sciences this year but I am very confused about the ACT/Subject test situation… It says they would like one math SAT subject test, but also says that they want the ACT OR SAT and 2 Subject tests. If I took the ACT do I still have to submit a math Subj. test? Probably going to call them because I’ll need to take the math subject test if it is required, thought I would check if anyone has info before.
