Toronto is an expensive place...... and you will need enough money to get you through to the point where you will actually be making money - and you still have to pay your staff while you are starting out. So, you need enough to pay the bills and the rent and the salaries for about 6 months, and also enough to support yourself for a similar period - PLUS what you will need to renovate any place you might rent. Count on $ 60,000 - to me that s a realistic figure.
this is something that you will either have to reseach yourself or ask a property dealer or estate agentthe rental costs of a shop will depend on the area where you intend to open while the renovation cost will depend on the type of renovtion you want to get done and materials that will be used for it, it is my guess that it will be anywhere from CAD $ 5,000 to 15,000 - the rest you can check out by getting the estimates of what you want
