Women, how do you deal with subway harassment?

I'm a young woman who recently moved back to Toronto after my studies. Unfortunately, whenever people are screaming they end up screaming at me. I'm a target for whatever reason. I usually ignore them and just turn up my music to not hear the abuse which works. Recently, frequently unstable people will hit on me or offer me drugs and then freak out when I reject or ignore them.

Today was the second time someone got in my personal space. I never engage and avoid eye contact always. However, today that didn't work when a man ran toward me and tried to put his arm around me. I ran away and he screamed obscenities at me.

I just worry one of these days one of these incidences will escalate to violence and I can't fight nor do I want to. So, women, how do you effectively reject such advances and protect yourselves on the subway? I'm now a bit scared to ride the subway because of these men as they are unpredictable and it's not nice to be screamed at or touched, everyone was staring at me but said nothing (as always).

Edit: thank you everyone for your thoughtful responses! It was really heartwarming to see how many people genuinely cared and gave lots of good tips that I will implement. Shoutout also to the guys who were here to support women/share their experiences. Its nice to see everyone coming together against harrassment💖🩷💖
