Can I quit without 2 weeks notice

Hi guys i just want to know if I can quit without 2 weeks notice , my boss is a horrible human being and extremely unprofessional, let me do all of the extra tasks that weren’t on the contract and lied about my insurance and all. I’m here for like 2 months and i just really want to ghost because of how horrible he treats his employees. However, on the contract that I signed it said i have to give them 2 weeks notice. But it’s not illegal in quebec to not give it especially if you work under 3 months. Would i get in any trouble if i quit immediately?
