Landlord served me with a bad faith N12

My landlord served me with a bad faith N12, saying he had sold the property and the new owners wanted to move in at the end of April. My lawyer did a search and found that the property has not been sold. The lawyer contacted them to ask for some clarification about who bought the place.

A day later, the LL had his real estate agent send an email saying that in the spirit of transparency, the house would go up for sale in April and he wants to stage the house and set up showings etc...

Do you think I have any recourse here? I mean, he flat out lied about already having a new owner on the N12.
