Vancouver is tops in Canada for quality of life with its moderate climate contributing to its high ranking, says an annual survey.

    The West Coast city has also retained its fifth-place spot globally in the 2012 Mercer Quality of Living survey.

    Overall, Vienna retains the top spot as the city with the world's best quality of living, also keeping its first place ranking, said the survey released on Tuesday. Baghdad was last out 221 cities.

    The survey said Canada offers some of the best quality of living in the world with Ottawa ranking 14th, Toronto 15th, Montreal 23rd and Calgary 32nd.

    "One of the things that Vancouver has going for it that the other cities do not have is climate," said Mercer Canada's Eleana Rodriguez.

    "All four of the other Canadian cities that are on the ranking don't have the kind of climate that Vancouver has, so obviously that's a factor to consider."

    Canada has five cities ranked in the top 35 cities in the world, she said, adding that Calgary advanced one ranking and Montreal dropped by one ranking.

    "We score quite high," said Rodriguez, market business leader for Mercer Canada in Toronto.

    Consulting firm Mercer looked at 39 factors such as a city's political and social environment and its economic and socio-cultural environment, areas in which Canada scored quite well.

    The firm also looked at medical and health access, education and access to schools, public transportation, recreation, availability of housing and consumer goods, as well as climate.

    "Vienna scores high on a number of those areas," Rodriguez said.

    The survey also found that Zurich and Auckland of New Zealand were ranked second and third with Munich taking fourth spot.

    The annual survey helps multinational companies and organizations compensate employees when they're placed on international assignments.

    In the United States, the top three cities were Honolulu, ranked 28th with the highest quality of living, followed by San Francisco in 29th place and Boston at 35th.

    Globally, the cities with the lowest quality of living are: Khartoum, Sudan; N'Djamena, Chad; Port-au Prince, Haiti; and Bangui in the Central African Republic.

    最新年度调查显示，加拿大温哥华因气候宜人，获评加拿大的最宜居城市。

    在2012年的美世全球最宜居城市调查中，这座西海岸城市仍旧位居第五位。

    从总体来看，维也纳仍旧蝉联全球最宜居城市。这份榜单于本周二公布。巴格达在总共221个城市中排名垫底。

    调查表示，加拿大成为全球最宜居的国家，渥太华排名第14，多伦多排名第15，蒙特利尔排名第23，卡尔加里排名第32。

    美世加拿大分公司的爱丽娜-罗德里格斯说：“温哥华拥有的其他城市不具备的优势之一是宜人的气候。

    “上榜的其他四个加拿大城市都没有这样宜人的气候，而温哥华独有，因此这明显是个考虑因素。”

    她说，加拿大有5个城市跻身榜单前35名。卡尔加里上升了一位，蒙特利尔下降了一位。

    位于多伦多的美世加拿大分公司的罗德里格斯说：“我们的得分非常高。”

    美世咨询公司考察了城市的39个因素，比如政治和社会环境、经济和社会文化环境，加拿大的城市得分很高。

    该公司还考察了医疗健康状况、教育和受教育机会、公共交通、娱乐消遣、住房制度、消费品购买、以及气候条件。

    罗德里格斯说：“维也纳在众多领域都得分很高。”

    苏黎世和新西兰的奥克兰分别排名第二、第三，排在第四的是慕尼黑。

    这份年度调查帮助跨国公司和组织为外派员工制定补偿机制。

    美国排名前三的城市为檀香山（在宜居城市中排在第28）、旧金山（第29）和波士顿（第35）。

    从全球来看，最不宜居的城市为：苏丹喀土穆、乍得恩贾梅纳、海地太子港、以及中非共和国的班基。
