请问加拿大的绿卡有时间限制吗？

拿到绿卡之后五年内，至少要在加拿大待两年， 否则，也会被取消资格

This is not true. In Canada, the green card is Permanent Residence Card, which is used to track new immigrant's total number of days staying in Canada. To apply for citizenship, you will require staying at least 730 days within a five year period.

If you stay outside of canada for a prolong period of time, it does not mean you will lose your PR Card status. Citizenship and Immigration Canada has to take you to court, i.e. Immigration and Refugee Board for the judge to take away your immigration status. If you have a reason to explain why you are away for so long, you will be able to keep your status.

For details, refer to the following link. If you want, read the IRPA, i.e. Immigration and Refugee Protection Act for more information.
