As for registering your business name ~ in Ontario under the Business Names Act YES if you advertize your business by any name other than your legal name you need to register it with Service Ontario .... however daycare is exempt from the HST, WSIB and other things so just click 'no' when it asks you you are only registering your BUSINESS NAME ~ it costs $60 and is good for 5 years .... benefit to this is also that you will get a Business Identification Number so you will not have to provide your SIN to clients on their tax receipt!
