Depends on what you mean by 'quarantine'.
In Canada if you are a recent traveler or suspect you have had close contact with someone who might have it then you are to go into 14 day isolation. That means not leaving your house for anything, even groceries.
Everyone in the country is expected to practice social distancing. That means only leaving the house for essential tasks like grocery shopping or to get some walking exercise. Groups no larger than 2 people.
The federal health minister has stated that social distancing will probably be in effect for months. I commented to my doctor today (via telephone) about being in for 3-4 months and she said to expect longer.
Sorry I was not clear enough I did not mean actual quarantine but the social lockdown which we got e.g. here in Germany, and which requires the government to support every company and workers, who cannot work anymore due to this.
But this is only the economic aspect of it.
Although some do not see this, but this solitary isolation or forced core family isolation can cause all sort of social problems too. Sometimes people still live together, but in reality should better have split up long ago, but I know cases where pairs are still together just because of the big house they own or the children they got, and before Corona they could both have their own social circle but this is not possible anymore.
Or if there is already a situation out of hand with domestic violence and now there is not even an escape for the victims.
For singles they got no possibility to meet people anymore. Especially if you are young and in this situation you might get irresponsible at some point if the isolating lasts to long.
