Troubleshooting

My question may have been unclear, perhaps this will help:

I already know that I will be required to register for an HST account. It appears that in order to register for an HST account, I will also need to register for a business number, and part of the required information in order to do so is providing the business name.

Is it possible (in Ontario) to use my own legal name as the business name when registering for a business number in order to be able to register for an HST account? Or, will I be required to use a name other than my legal name in order to get a business number?
