我曾就这个问题专门给加拿大驻北京大使馆发email询问过，也在他们的网站上查到过相关信息。
得到的结论是：如果是多次入境签证，只要在你自己的签证过期前入境就可以。但单次入境签证通常须在拿到签证的6个月内入境。
（1）使馆给我的回复摘要：
Dear Sir/Madam,
The EXPIRY DATE on your visa means: you must ENTER Canada before this date.
The visa validity is determined by a visa officer. Single-entry visas are normally valid for six months, and multiple-entry visas may be valid for longer periods. Please make sure you clearly indicate your intended travel date on the application form.

（2）使馆网站相关信息：
What does the expiry date on my visa mean?
The expiry date on the top line of the visa is the date by which you must arrive in Canada, not the date by which you must leave Canada. You must arrive in Canada on or before the date printed under "Expiry date" which is read DAY-MONTH-YEAR (DD/MM/YY).
