180,000 small businesses in Canada may close down, which will have an important impact on the local economy. Although small businesses do not contribute as much to the economy as large businesses, the combined contribution of 180,000 small businesses is very large. The collapse of so many businesses is bound to have a major impact on the economy. This is because in a market, in addition to large companies, there are also many small companies. The market share occupied by large enterprises is relatively large, but they still account for a large part of the market share, and these market shares will be occupied by small enterprises. If small businesses close down, it is likely to cause an imbalance in supply and demand for this part of the market. The demand for many products on the market will increase sharply, while the supply will further decrease. Have a significant impact on the economy.

In addition, there are some markets where companies do not control a large share. Because the degree of differentiation in this kind of market is relatively high, the forced closure of small businesses also means that the vacancy in the market will become very large. In normal economic development, changes in the relationship between supply and demand do not have major fluctuations. However, due to the impact of the COVID-19 epidemic in 2020, many companies' capital chains have been broken, and there is a risk of bankruptcy. Faced with such a serious situation, the closure of enterprises means that there will be a large vacancy in the market. The vacancies in this part cannot be filled in time, so people's demand for this item further increases. This will indirectly cause the price of this item to fluctuate abnormally and increase sharply.

In addition, in order to meet people's needs, the government will make up for this gap by importing goods. This will also lead to the outflow of national capital. Therefore, in many daily necessities industries, if a large number of companies close down, it will inevitably have an important impact on people's quality of life. Therefore, Canada will experience a trade deficit in these months. At the same time, we can also see from the indicators that economic indicators are generally based on GDP and CPI. The closure of enterprises indirectly affects the relationship between import and export, which will have a greater impact on the calculation of GDP. Therefore, the closure of so many small businesses in Canada will cause a significant decline in the total contribution to the economy.

At present, what the Canadian government needs to do is to control the epidemic. Only when the COVID-19 epidemic can be gradually controlled can we begin to resume work and production and restore the domestic economy. If work and production are resumed hastily, it is likely to lead to further spread of the epidemic.
