PLZ, HELP. Some questions about how to apply for a Visitor Visa online from US??

[HOPE :)]

Hello all

I want to visit my family but I need to get a visitor visa first to fly to Canada. I am collecting all documents but I have some questions, please I hope anybody can help me about this.

In my documents checklist says:

- Business Registration:

Use of a Family Member Representative for Online Applications (IMM5713)

What does that mean???


Thanks
