I guess I was lucky. I found a company who wanted me and went through the whole LMIA process, employed an immigration lawyer to sort out my work permit, my wife's work permit and all the permits for my kids. They also employed me on contract to work remotely until all the official stuff was solved. I've been here just short of 4 weeks.
They even couriered me a company credit card so that I could use it to pay my quarantine hotel bill.
So it is possible but from what people are saying on here it is quite rare.
