A graduate program (law school) that may be of interest to OP is the Michigan State University College of Law dual degree program. This is a four year program in conjunction with the University of Ottawa School of Law. Students spend two years at one law school, then two years at the other law school. After three years a first law degree is awarded and after four years a second law degree is awarded. The student then has both a US law degree & a Canadian law degree.

Also, I believe that the University of Colorado School of Law offers a similar dual degree option with a different Canadian law school that may or may not be still active. It is / was in conjunction with the University of Alberta Faculty of Law.
There is at least one other program of this type between a US & Canadian law school.
