I currently live in ND and have for over a year and have a 4 yo domestic violence injunction against me in FL. How can I get the DV inj. dismissed?

My job is requiring me to travel into southern Canada on a regular basis for work beginning in Jan 2013 and I can not gain entry to Canada with an injunction against me. If I am unable to get this cleared up I will be let go as I am the field mechanic for an oilfield support company. The DV inj petitioner is my ex wife and we have been divorced for 4 years, have no children together, have had no contact for 4 years and she still lives in FL as far as I know. There was also never a crime of DV committed againat her by me, she basically got the DV inj so I would be forced to leave the home and she could stay in it. Would not the fact that I have established residency in a state 2500 miles away and the fact that we have no children and no reason for contact make her claim of fear of imminent danger moot?
