Hacking law in canada

My boyfriends ex called the police on him trying to say that he hacked her e-mail account and all this stuff, which he didn't do (because I'm with him pretty much all the time so I'd know). Anyways, so the police called him and he was like 'No, I didn't...what could you even charge me with anyways?' and the police man was just like 'Okay... Have a good day!' So, my boyfriend is trying to tell me that he wouldn't even be able to get charged because there isn't a law against it. His friend Paul had recently tried to charge someone with it and didn't get anywhere, and he had a lot of proof. I'm just wondering what the law is in Canada for that... because we are always talking about hacking in here. Are police just not taking it seriously or what?

I'm pretty sure that hacking is illegal almost anywhere.
Lord knows it is in the US.
They probably just didn't believe the ex, seeing as how she had no proof.

Yeah but my boyfriend's friend had a lot of proof and the case still didn't go anywhere. The proof included several pieces of evidence where the person was even admitting to doing it! I know hacking is illegal, but I don't think its being taken seriously enough here.

They probably dont do anything unless there's an actual loss (I.e. someone stole data, hacked into somewhere and spread a virus...)
