I don't think this is a question of resources. On an application—family members are defined in IRPA—there's a tight definition. The reason for this is that, down the line, if we have a tight definition and somebody comes in, they can't then sponsor their uncle or their cousin. If the intention is to keep people out of Canada, then they should be sanctioned individually.
I would say that under the current regime, this can be done, and recommend that it is what should be done to protect Canadian society.
