OTTAWA—Canada's western city of Calgary is the world's best city when it comes to healthy living, local press reported Monday.
According to an international survey by Mercer Human Resource Consulting, a Londonbased consulting firm, Calgary was put at top of a list of 144 cities. It scored 121 points, just above Honolulu's score of 120. Helsinki (赫尔辛基，芬兰首都) and Ottawa followed at 119.5 and 118.5 respectively.
Three other Canadian cities came in the top 20. Montreal and Vancouver tied for 9th and Toronto came in at 18th.
