I see significant differences though.
This article says in Quebec "Grocery stores and depanneurs must close at 7:30 p.m. every day to allow shoppers time to get home." Also
this article says, a Sherbrooke couple were each given $1,500 fines by police for walking outside after curfew near their home (humorously, she claimed she was "walking her dog" as he had a collar and leash).
In Ontario, the hours of grocery stores haven't changed with lockdown and you are allowed to exercise outside anytime. Totalitarian comment aside, it just makes more sense to allow people to shop for groceries and exercise over a wider time period to reduce crowding, since close contact is what we are trying to reduce.
