When I received the refusal letter i contacted many lawyers and they told me that I can appeal the decision at the federal courte house, but it takes time and costs alot of money ( between $ 4500 and $ 7000) and the result of the appeal is not even guaranteed. I asked some friends of mine and they told me why dont you reapply? I thought about it and I ened saying to myself why dont I reapply lets take another chance, it s a good idea!! it s gonna cost me just a new fee wishs $ 550 and i have to get a copy of IELTS and police clearance from canada and from my home country. in about 1 month after the rejection letter i had all documents. I sent my application and I got an email just after one week confirming that my application for PR was received, another week after I got AOR with medicals. I was so surprised and I couldn't believe it was that fast. I did my medical next day and I am still waiting now. hopefully I hear from them some good news.
Don't ever never loose hope brother,as long as there is hope there is life.
