Question on finding a child support/spousal support case/ruling like mine in Ontario?

I'm in what I believe to be a unique situation. I am the father of two kids - sole custody (custodial parent) and I need to find if there are any existing cases/rulings in situations like mine as it relates to how the need for child support supersedes spousal support. I have access to Canlii.org but there are SO many cases out there. If there are any lawyers or paralegals that can at least point me to some specific cases that might be similar that I can review, I'd REALLY appreciate it.
