Over time, Vancouver has become a service centre and, after the Expo 86 world exhibition, a tourist destination. The city is the third most important location for the North American film industry after Los Angeles and New York and is therefore also known as ‘Hollywood North’. The financial sector also plays an important role. In a ranking of the world's most important financial centres, Vancouver ranks among the top 20. Vancouver is considered one of the world's major cities with a very good quality of life.
