一艘观鲸船在加拿大沿海沉没五人丧生

At least five people are dead after a whale watching boat sank Sunday afternoon off Canada\'s west coast.

It is not yet clear what caused the boat to go down near Tofino, British Columbia, with 27 people on board.

The Joint Rescue Coordination Center said 21 people were rescued and one was still missing.  Most of those rescued were taken to hospitals.  A spokeswoman for Island Health said one person was in serious condition, but stable.

The boat was operated by Jamie\'s Whaling Station, which takes people out on boats for several hours in the waters around Vancouver Island to see Gray whales and Humpback whales, according to its website.

The company said late Sunday it would release more information about the incident later after focusing on the rescue efforts for the passengers and crew.

联合救援协调中心说，21人获救，还有一人下落不明。获救者都被送往医院，其中一人伤势严重，并无生命危险。

这艘船由杰米捕鲸站营运。根据其网站的介绍，游客在温哥华岛周围海域坐船好几个小时观看灰鲸和座头鲸。

该公司周日晚间表示在集中精力救援乘客及机组人员后，将发布有关事件的详细信息。
