There are a number of different sources that you can consult to approximate the size of a market. Remember to make some provision for errors in your estimate of market size as finding completely up-to-date information is difficult. A key source of up-to-date Canadian demographic data can be found on CANSIM on Statistics Canada. CASIM is updated daily and you will want to pay particular attention to Table 551-0002 which has information on the number of businesses in each province or territory, employment size, and types of businesses (Good et. al, 2021).
