The RBTT group of companies operated several commercial banking businesses in other neighbouring islands, as well as various investment holdings in various parts of the Trinidad and Tobago economy.

The head office of the Caribbean operations for RBC will be located at Port of Spain, the capital of Trinidad and Tobago, and the site of RBTT's headquarters.

RBTT's history in Trinidad and Tobago began in 1902 when the Union Bank of Halifax, based in Nova Scotia, Canada, opened a branch in Port of Spain.

In time RBC expanded its operations from a single location to several different branches across Trinidad and Tobago.

In 1990, RBTT decided to transform The Royal Bank of Trinidad and Tobago Limited into a full-fledged regional institution offering financial services across the Caribbean.
