Three months ago, Martine sold a dwelling which was her main residence. She still owns another dwelling which she uses as a holiday home. Since the sale of her main residence she has lived in rented accommodation.
Martine then purchases a dwelling which she intends to use as her next main residence.
At the end of the day that is the effective date of the transaction, Martine owns two dwellings, but as she is replacing her main residence (she is purchasing her next main residence within 18 months of selling her previous main residence), the ADS will not apply.
