CRA rules will allow a rental loss on one property by claiming CCA "if you are claiming more than one rental property". As you are required to complete a separate T776 for each property, this should "only" be happening if you are filing more than one T776 form. TurboTax is set up to limit the CCA claim so a loss is not created or increased on your rental property.
Please advise us if this is not the case and a loss is being claimed in error. Thanks 🙂
