You can be evicted only for the reasons set out in the Residential Tenancies Act.
If your landlord used a Landlord and Tenant Board form, it will already have the reason for the eviction. Or the form will have a list where your landlord must choose the reason for the eviction.
If your landlord did not use the Board's form, you should check the Board's list of reasons for eviction.
If the notice does not give a proper reason, or does not give enough details, then the Board can decide that your landlord cannot use the notice to evict you. But you will probably have to go to a hearing of the Board to make this argument.
