Take a look at the provincial breakdown. The Atlantic provinces are in a position where kids are going to school, restrictions are being lifted, and the number of cases are in the single digits per week. For the most part, there is not spread within these provinces so efforts can focus upon verifying that people coming into the province aren't infected and ensuring the population complies with far less extreme measures so that the virus does not gain a foothold in the region yet again.
Even parts of the country with a far greater number of infections than the Atlantic provinces are seeing numbers stabilize (e.g. Alberta) or decline (e.g. British Columbia). This is not the case in Ontario, where the spread is essentially uncontrolled. Measures need to be put into place because the living will continue to suffer as long as that spread is uncontrolled, and yes the loss of life matters as well. A few weeks to stabilize the situation will ensure that lives are not lost needlessly.
