If my GPA is below the entry requirement of the graduate schools

It could not hurt. Better yet, how about get a job, join the real world, or, if you qualify, join Canadian Forces. Save some money. Then, if you still wish to go to grad school, you would be applying as a “non-traditional” applicant whose most recent academic performance would carry less weight, especially if it becomes a few years old. It appears your heart was not completely in it during undergrad or you would have had a better GPA, regardless of any commitments you had outside of just going to school.

Meanwhile, lackluster as your performance was, you do still have that undergrad degree and someday you should get some chance to capitalize on it in some way.
