Lightning can support bidirectional charging though the Ford Home Pro 80 amp charger, which originally came free with all extended range battery vehicles. It also requires additional work on your home's electrical panel, to be done by a Ford-approved electrical contractor. I haven't heard of many Canadian owners who went that route, as it was quite expensive.
The quick and dirty way to do it is to get an electrician to collect 4-6 circuits you want to power in an emergency and drop them into a subpanel that is co-fed by an exterior 240V receptacle. In a power outage, shut off the home's primary disconnect, then connect a heavy gauge extension cord from Lightning's 240V 30A bed outlet to that 240V wall mount receptacle. It's enough to run fridge and freezers, lights and plugs. Sewer lift pump if you have one of those.
I mapped it out with an electrician I use a lot in my business. He estimated $1200-1500. I didn’t do the install because power outages are very rare for us. We are within 1 km of the substation and the street is all underground power.
