If your office is thinking that this is just another dumb farmer - let it be known that this dumb farmer is not going to give up on this matter.

Nothing dumb about you, sir, and I salute an individual who is prepared to stand up & be counted. I have just returned home to the DR after a trip to my country of origin, UK, & was frankly appalled at British citizens seeming apathy in the face of being walked over by their Government, so it is truly refreshing & reaffirmative of one's faith in human nature to see an indivdidual such as yourself stand up to your own Government. I would agree that the issue would probably benefit from getting press coverage on your side & also wanted to suggest a couple of other things - bear in mind I am not Canadian & know precious little about how Canadian Immigration works, or rather, doesn't, judging from your experiences, so if these suggestions seem useless please excuse my lack of knowledge.
Would there be any mileage in getting the DR Embassy in Canada as an ally in this matter? The other thought which occurred was that there are human rights issues at stake here - exploitation of some members of a developing country by a first world country. Could it be that Human Rights Watch might be interested or maybe the UN? Would there be any mileage in getting a Canadian Law School interested as a practical piece of work for some of their postgrad students? This might take some of the weight of the 'struggle' off your shoulders and into the hands of some young enthusiastic students who could also delve into any other shady/inefficient dealings by Canadian Immigration authorities.
