I'm the Canadian who was detained by ICE for two weeks

Yea that's scary. I was in a similar situation, but thankfully they just interrogated me for 5 hours and then sent me back to Canada.

My name was marked from that point, so everytime I re-entered US I had to get pulled into secondary.

My sister accidentally brought a banana across the border from Canada into the US 20 years ago and because of that she gets secondary inspection every time.
