Can an International student study in community college without a Highschool Diploma?

Hello everyone, I’m new to this forum and I need your opinion on this, do you suppose that an international student could be able to attend a community college in Canada without a Highschool Diploma? My friend has a certificate of completion (plus very good grades, I’m talking 3.7GPA + 7.0 on IELTS) but dropped out right after she got her certificate of completion due to personal reasons, she’s 19 years of age (so that’s considered mature student), do you think she can apply to a college like Seneca or Sheridan and study? I really love her, she’s very great and she really doesn’t deserve what has happened to her, I really want to be able to help her, can someone please answer?
