If the tenant wants to move before the end of a fixed term tenancy, the tenant will have to continue to pay rent until the end of the term unless the landlord agrees in writing that the tenant can end the tenancy early or can assign or sublet the unit, or if the landlord is able to mitigate the potential loss by renting out the premises. If the tenancy is for a fixed term of six months or more, the landlord cannot unreasonably withhold consent to assign or sublet.

As taken from the residential tenancy branch website. Just try talking to your landlord and see if he's willing to work something out with you like a 1 month penalty or something
