As per EVs... 10 years ago we had iPhone, BlackBerry and Android, which are replaced every two years. Today the average Canadian family cannot afford an EV not only because of economic factors, it's also not practical for many people without more fast charging stations and technology. Also vehicle age of vehicles on the road is 10 years. In 10 years I hope they're more widespread but we're at least 20 years away for having a majority of ev on the roads. In the meantime, we need oil, Canadian and local if possible.
