I have the same problem this year - got this message below that blocks Netfiling and yet I don't have any business income. We have a rental property in Florida, so put in the US address. It was no problem for the past 7 years.
Any advice?
Your business or rental address is missing information (i.e. number and street) or it has a character that can't be used. These include an ampersand (&) an asterisk (*), spaces after the entry or a period as a first or last character. All address fields must also begin and end with an alpha or numeric character. As well, your postal code must be valid and match your Province of residence.
