If you have a claim in tort against the landlord then the fact that you broke a contract with the landlord is (almost certainly) going to be irrelevant. Your question is not much different to saying, "suppose I cancel the direct debit on my mobile phone contract, can I sue Vodafone if they send an employee to break my legs when I'm walking down the street?" Of course you can, because "he breached a contract" isn't a valid defence to a tortious claim.
That's not to say that the landlord might not have some other defence, since you barely provided any facts, but the mere fact of a breach of contract is not likely to be one.
