Sponsoring your family:
Eligible relatives―How to apply
The application process involves two steps:
You, as a citizen or permanent resident of Canada, must apply to be a sponsor and then be approved.
The eligible relative(s) must apply and be approved for permanent residence. Application forms for your relatives to fill out will be sent to you in Canada after the Case Processing Centre of Citizenship and Immigration Canada in Mississauga, Ontario, reviews your sponsoring application. You should ensure that the correct number of application forms are mailed overseas to the relatives you want to sponsor for permanent residence.

Sponsoring your family:
Eligible relatives―After applying
Once you (the sponsor) have been notified that your application has been received, you can check on the status of your application online through the I Need To… section on the right-hand side of this page. You can also check through the Call Centre (see Contact Us at the top of this page).
The Case Processing Centre (CPC) of Citizenship and Immigration Canada in Mississauga, Ontario, will review your application as a sponsor. If you appear eligible to be a sponsor, the CPC will send you the application by courier. You will receive a blank permanent resident application for your overseas relatives to complete and submit to the visa office in their home country. The application will be processed there.
If you fail to meet the sponsorship requirements, the CPC will tell you. You may have stated on your application to sponsor that you want to continue with your application even if you are not found eligible to sponsor. In this case, the CPC will forward your application to the visa office, but it will not necessarily be approved. Your application kit explains this process in detail.
If you are approved as a sponsor and the person(s) you are sponsoring has her or his application refused, you will be notified and given the reason for the refusal and information about appeal rights. You may be able to appeal the decision to the Immigration Appeal Division of the Immigration and Refugee Board.
家族のスポンサーになる場合は、先にスポンサーになれるかどうかの審査を受けないといけないんじゃないでしょうか?スポンサー合格だと、スポンサーをする家族に対しての申請書が送られてくるから、それを海外の家族に送る、、、と書いてあるので、スポンサーされる家族は海外にいなくてはならない。と私は解釈しましたが、違っていたら補足をお願いします。
