Panther can not, and does not, force you to go anywhere. They do, however, penalize you for refusing to go to Canada, by decreasing your CPM rate by .02, I believe. The penalty does not apply for refusing one or two loads, but a blanket refusal to go. I'm not sure when that point is reached, if one simply turns down every offer to Canada, but what I've heard is a quarterly period. Maybe someone who knows for sure will post it, otherwise you need to call Panther recruiting to get the facts.
