What expect from the OCL disclosure meeting/ report?

Hello,

Location: Ontario, Canada

I am about to have a disclosure meeting from the OCL regarding a grandparents rights case. What can I expect from this in terms of the OCL's decision?

I'm wondering if the OCL is fairly formulaic and the recommendation will be very evidence based or if there is a lot of room for clinician judgment/ opinions?

I understand they are supposed to be impartial but in practice does the personal opinion of the clinician end up dominating anyways?

Factually, my case is fairly straight forward- I'm seeking to prevent contact with paternal grandparents who are verbally abusive to myself and my spouse in front of the children, they haven't met all of my boys and the others they have not seen regularly in 5 years with no contact at all for 2 years. My kids are young, with minimal to no memory of the grandparents who have never been caregivers. My wife and I are 100% united no contact, married, no issues, good job, etc..

I know that factually, this isn't a case where they are likely to win but I get the sense that the clinician has a soft spot for grandparents, he has said "I'm a grandparent myself" and I'm nervous that this is going to translate to partiality. The grandparents are also big liars- we have proof of this in writing but obviously lots of people claim the opposing party is lying during these type of proceedings.

My question is: can I expect a big emphasis on the facts or will there be lots of consideration of the clinicians personal opinion and lots of room for interpretation? The whole process has been so nonsensical. I'm nervous and feel I need to mentally prepare if this disclosure meeting might go poorly for our side.
