Structured data for business listings

[EBKMarketing]

If I have a page of 20 local business listings, do I need to provide structured data for each business listing? is that necessary and would it help with SEO?

So if I have a page of  Vancouver Brain Injury Lawyers, and list off 20 local law firms that focus on that type of injury, should I have structured data for each law firm that I list?

I would recommend to have structured data for each individual listing. Try to structure as much information as possible and this should help the search engine and your SEO.
