Vancouver boasts a thriving hub of a downtown business district with a surprisingly small radius – 20 by 20 square blocks. The district is bordered by Stanley Park, the West End and Cambie Street, and is located between the Burrard Inlet and False Creek. The industries with the largest portion of head offices in Vancouver are mining and forestry, followed by construction, food distribution, retail and financial services. Vancouver's port ranks 20th in the world and is one of the busiest in North America.
