This is not to be taken lightly. You were issued an I-275 and rendered inadmissible. Further attempts into the U.S. could be very seriously jeopardized unless you consult an immigration attorney familiar with your situation.
Remember, when CBP issues an I-275, this is just the DHS's way of saying; we are going to be nice about things and let you withdraw your TN application without facing the more severe repercussions of appearing before an immigration judge.
It does not mean you cannot reapply for TN. However, it does mean you have to be very careful with future entry attempts into the United States. This would include showing explicit immigrant intent while attempting to enter on a non-immigrant status including TN.
There was a story about 2 years ago in the summer of 2007 about 2 Ontario men who wiped out on their Seadoo and washed ashore on New York soil undocumented. They were taken into CBP custody and had to appear before an immigration judge.
That is how serious these types of encounters can get at the U.S. border and the DHS has the power to do many things under the law including deportation, expedited removal, and assigning mandatory appearances before an immigration judge.
