我在加拿大留学，大签马上过期了，我准备网上续签，但是发现旧的那张大签找不到了，怎么办。

先补办你的大签，之后再申请续签

如果丢失了STUDY PERMIT，你可以另外申请一份。你必须填写申请表格，并且付申请费。

联系CIC呼叫中心，Contact the CIC Call Centre (seeContact Usat the top of this page) or see theRelated Linksbelow for more information.

There is a fee for replacing immigration documents that have been lost, stolen or destroyed.

先到大使馆去 你有复印件吗？ 没的话需要查你登陆证明 （防止不是偷渡的） 号码知道吗？

额。。。续大签的时候需要大签的复印件么? 我印象中好像不需要额。。

你还有你第一张学签么？ 上面有你的client number..

再不行的话，那就只能打电话到移民局要他们给你邮寄一份了

提供client number给移民局，要求补办。或者打电话给移民局问清楚可否在续签的时候写信说明情况，因为移民局通过client number可以查到你的签证细节。

是护照丢失了吗？去中国驻加拿大大使馆办理临时护照，不过时间很长。实在不行只能回来做续签了，如果你留学记录良好，没有缺勤并且成绩尚可的话，在国内续签没有太大的问题。

您好；
续签可以不同提供旧的那个，因为CIC都有可以查到你原来SP的情况的。
