Filing revenue from e-commerce store and mobile application

[mmo124]

I live in Ontario. I have built a mobile phone app but for various technical reasons I was not able to launch it in the stores(Apple and Google) yet. The app will be generating revenue from advertising and subscription. I have a few expenses attached to this. e.g. server cost, code repository cost etc. I have purchased a computer specifically to work on this application. 

I have built - but not yet launched 2 online stores: 

Store 1 - selling some of my own custom art. 

Store 2 - selling generic art supplies and stationary. 

Both stores have server, google service fee and other cost associated with them.  

I do not want to register a business - yet. For now these are all experimental. I

When I start making money from any of these sources how do I report in taxes? 

P.S. Not sure if this is important but I make slightly over $120,000 from my day job - I receive T4 from my employer.

I have a rental property that makes approximately $30,000.
