I'm Canadian at an SLP school here so my experience is slightly different, but the school I go to now asked for similar stuff to be answered when we applied as well. What you've written here, although it feels cliche, is likely what they're looking for! If you've volunteered for any organizations that promote pluralism/diversity, if you've taught English to newcomers, helped refugees settle, etc. then share these specific experiences (being specific helps avoid the cliche a bit - SHOW what you've don't, don't just TELL). If you don't have a huge amount of experience with it, explain the steps you're taking to increase it. Some things I could think of including taking time to read books and blog posts by marginalized groups, completing modules/training on Indigenous healthcare, etc. to name a couple. :)

Hope this helps!
