One Atlantic is a project to create a unified identity for TJX Canada's presence across the Atlantic provinces. I designed a unique and recognizable logo that resonated with the regional market while adhering to TJX Canada's established brand guidelines. The creation of a comprehensive brand guideline document for One Atlantic solidified the choices and decisions made. This document detailed the logo's design rationale, including choices related to colour palettes, typography, and imagery, and provided clear instructions for its correct usage across various applications to ensure brand consistency and integrity.
