My company wasn't like that at all.
And further more, if a woman is married to a man for 25 years and willingly has sex with him everyday and one day out of the blue, she doesn't want to...and he does it anyways, it's still considered rape. It's the same thing with harassment. Just because they started out friends doesn't mean that you're still not a victim.
When I was a child, I was put in group homes for abused kids. (My mom was a crack addict who was starving us and beating us half to death all the time.) I was eventually taken away. When I was 15, I tried to run away. While I was on "the streets", I lost my virginity to a rape. I held it in, but it was killing me. I told my older sister, and she told me to tell my Grandma. So, one night I did. Instead of having pity for me, she acted like it was my fault because I ran away. It just goes to show how misconstrued people's conceptions can be. Basically, long story short...if someone is doing something wrong to you, take action for it. You're still the victim, no matter what anyone thinks. Keep going to HR until they fix it. Log every thing that happens and keep them updated. If HR won't handle it, take it to the General Manager, or the VP or even the President if you have to. If that doesn't work, then call the (I'm not sure what it's called in Canada), numbers they should have given you to stop harassment. The company should come to your aid. If not, then there are laws to protect you.
