<p>In my neighbourhood, Minnesota and North Dakota have (or have had) agreements with Manitoba and possibly Saskatchewan for in-state reciprocity. There may be other states and provinces with agreements. Even amongst guidance cousellors in these states and provinces, the agreements are not well-known. Only about 50 Minnesotans make use of the agreement to attend one of Manitoba’s fine universities and about the same number of Manitobans attend a Michigan university under the agreement; most attend the U of M in either jurisdiction (U of Manitoba and U of Minnesota).</p>
<p>I have had ex-students attend Humber for music and they have thrived there. The focus is on popular/jazz/commercial music, and I too don’t know anything about what it offers for composition. </p>
<p>Academic entrance requirements are usually somewhat more relaxed for music applicants at Canadian universities. Also, because of different Canadian grading standards, the OP’s academic record is not a weak as it sounds to American ears. Typically, in Canada 50% is a pass, and 80%+ is an A, so 70 to 79% is a B. Additionally, most Canadian universities do not look at a student’s entire transcipt. Many look only at 5 to 7 grade 12 courses and totally ignore all the other marks. I have certainly seen less that stellar students admitted to the music schools at places like McGill (provided they are excellent musicians); I’m not sure whether the OP would be in the running, though.</p>
