Need an experienced tax person for retirement "account" established in Cayman Islands

A prospective client of my firm worked for years with a large hotel operator around the world. Because he was a Canadian citizen, they established a "retirement account" for him in Cayman Islands. He now is ready to retire and move back to Canada and I am looking for someone with a referral to a tax person who understands Cayman investment account structures.

I've asked to get a copy of the plan details or an account statement from this prospect to clarify the exact structure his company used.
