Hello Ahmed,
Under Ottawa’s short-term rental by-laws, apartments and condos are not permitted for short-term rentals of less than 30 consecutive nights. If you intend to rent the unit for longer than 30 days, it’s important to review the specific condo bylaws, as they may have their own minimum rental period restrictions in addition to the city’s regulations. You may list on Airbnb a condo for monthly rental, providing the condo by-laws allow it.
