I understand where you're coming from, and the same logic is why so many people major in polisci, philosophy, and criminology as a precursor to law school.
The reality is that there's no correlation between legal experience/education and success in law school. Admissions committees know this.
Additionally, there's a lot of value in accepting students with diverse educational and professional backgrounds. It makes for better, more educational discussions in the class room.
Nobody in admissions at any law school in Canada is going to be impressed by a paralegal degree. Just because people with that background got in to law school doesn't mean that they were admitted for that reason.
The heartbreaking thing about the child protection work I did was that there were just no good options - just varying levels of shit. CFS wasn't getting involved without some good reason, but putting children into care for either a short or long term was hardly very good for them either.
