Sir

I presume that you are asking for property in Canada. If you are using small business/ profession from your home then there is no problem in India and generally other countries also allow it unless it is in a big way or disturbing the local peace. Canadian lawyers will advice you better but I think if the business is small then you will find the option to do it from your home.

good luck
