I would like to add something onto it in regards to your question, First of all before deciding on any application case officer will look onto your "STRONGER TIES" and where they are established more. It doesn't really matter if you have family member outside Manitoba ( But you must disclose it in your application), if he/she is less settled/established than your supporter ( Doesn't matter your family or friend) will clarify and support the application.
In clear words, a supporter can help you settle more successfully than your family member who is less established than your friend supporter or vice versa.
Regards
