搞到nissan Canada 和OMVIC
1. 搞到nissan Canada 
    It may give you some compensation or  fix/paint in free for you.
    In my case, Audi Canada requested the dealership to take my car to a professional Bodyshop to repair and paint, cost about 1000 dollars,  free of charge of me.
    Audi Canada offered me one month's payment. And the Dealership offered me to change a new one.  I refused both of their offers and requested to just return back.
   I raised the issue to  OMVIC for the settlement.
2. 搞到OMVIC
   No helps to our consummers but maybe left a bad record to  Nissan'S REPUTATION.
  Why ?
  Here are some reasons:
- OMVIC is a organization to resolve those issues raised by consummers; however, all those Auto Makers are members of this organization;
- OMVIC DOSE make a record for Nissan if you complain it and will affact , somehow,  its reputation; 
- Nissan will use its resourse to dea with OMVIC but not you;
- Finally the OMVIC will send a Adjuster(similer to a middle man, but his/her judge is final as the one of court) to make a judgement on your case, which 99% probabaly  will favour the Auto Maker, not the consumer. That's all !
Above is my experiences with Audi and OMVIC.
I did not try and am not sure that to have a lawyer or involvement of media more useful or not.
  
Good lucky !
