The Emirate of Abu Dhabi is the largest of the seven-member United Arab Emirates. Its capital is Abu Dhabi City, the second largest city in the UAE after Dubai. The city is also the federal capital of the UAE, housing the government and the president's office. It's a regional and international hub for trade and commerce, with many multinational companies maintaining offices in Abu Dhabi and of course a large presence of the petroleum industry.
Abu Dhabi owes much of its wealth to some of the largest oil reserves in the world. Following the discovery of vast oil reserves in the late 1950s, the emirate started a phase of rapid growth and development. In a few decades, the city of Abu Dhabi grew from a sleepy fishing village and trading post for nomadic bedouins to a thriving, glitzy commercial hub with skyscrapers overlooking the rapidly expanding city. The inner city itself sits on a T-shaped island and features many waterfront sites, beaches and canals.
Estimated by some to be the wealthiest city in the world, modern day Abu Dhabi is a great place to live for international expats. Around 80% of the population of the UAE are foreign expats, making for a very lively mix of cultures. Food and products from all over the world are easily obtainable, and you'll find great options for dining. The cost of living is very reasonable - most basic staples won't cost any more than in the US and are generally cheaper than in Canada. Thanks to Abu Dhabi being a large exporter of petroleum, gasoline is only around $0.30 per liter ($1.25 per gallon).
You'll find plenty of modern amenities: malls, hotels, restaurants, coffee shops, supermarkets, museums, theatres - you name it and Abu Dhabi probably has it. Among the more interesting attractions are the Ferrari Theme Park, an indoor ski hill, and the Emirates National Auto Museum, a pyramid shaped building housing the car collection of Sheikh Hamad bin Hamdan Al Nahyan.
