No you can’t.
1. You have to fly and quarantine. Many people out of jobs and not making money can’t afford to fly.
2. If your family is in Niagara Falls, NY and you live in Ontario are you going to drive to Toronto and catch a flight to Pittsburgh Or Cleveland and drive up to Niagara instead of driving 10 minutes.
Travel is restricted. There are probably limited flights from Toronto as well. Probably not flying to Pittsburgh or Cleveland anymore and you may have to fly Toronto to NYC to get from Niagara Falls Ontario to Niagara Falls NY.
I’m sorry but no athlete should have a priority over playing a sport than people do visiting family.
