"would simply require the Minister of Immigration to give flexibility to undocumented applicants on a case-by-case basis"

The reason the minister of immigration has this flexibility is to deal with rare ane exceptional circumstances.  If the minister exercises this discretion for thousands of DREAMers then the reality is that Canada is simply breaking its own immigration rules.  And that is not right nor is it fair to all those other would be immigrants who are following the rules as they are written.  

Sorry, but DREAMers are an American problem.  We do not need to get involved.
