If passed, law enforcement will be able to access internet company's (Bell, Videotron, Rogers) customer information such as:

• client's name.
  
• phone number.
  
• IP address.
  
• web data.
  

With this one can find out:

• what web sites an individual has gone to.
  
• someone's surfing habits online.
  
• what videos they're viewing. 
  
• what content they read. 
  

They will not be able to:

• Read your email.
  
• Access data on your computer
  

I know there is already a lot of controversy around this, but if you take a closer look at Google, and there ADs technology, Google already does this.
