Optometrist/Associate revenue split, Canada

How much would an associate optometrist give to the owner Optometrist?
Would the associate optometrist give a percentage to the Optometrist owner for OHIP and non-OHIP diagnostics?
What would be the dispensing percentage split? (glasses/contact lenses)
What is the norm? I appreciate that this is negotiable.
Thanks
Perhaps the answers should be pm'd?

In all of the practices I have consulted with over the years, the norm is 50%, the owner provides the space, receptionist, pre-testers, equipment and inventory.

(Eye exam revenue + dispensing revenue) - COGS = Net Profit / 2
