The best place in the world to live

Vancouver is the third biggest city in Canada. It’s in the south west of the country and it has a population of 2.6 million. A recent study showed that it’s the best city in the world to live. The study looked at areas like weather, transport, education, healthcare, and safety. This study happens every year and Vancouver is usually number one.

We asked Vancouver resident Jacob Meyers if he agrees.

I’ve lived in Vancouver all my life. I work for an engineering company and I’ve travelled on business to many Canadian cities. Two years ago another company offered me a very good job in Montreal but I didn’t take it because I never want to leave my city. Let me tell you why not:

Vancouver is situated between the mountains and the Pacific Ocean. That means the summers aren’t too hot and the winters aren’t too cold. It also rains a lot, in summer and winter. Some people don’t like that but I do because our gardens and parks are always green and fresh. Every day I cycle or walk for an hour in a park and in Vancouver you’re never more than a few minutes from one.

I don’t feel frightened when I walk in Vancouver’s streets at night. Of course, Vancouver has a high population and there’s crime in every big city, but compared to the USA, for example, it’s quite safe.

But my favorite thing about Vancouver is its incredible mix of nationalities. I’ve got friends here from all over the world. And there’s an enormous variety of foreign food in the restaurants and markets. I’ve eaten wonderful dishes from China, India, Italy, Greece, and Japan and I haven’t been to any of these places.
