A few decades ago I was chatting with an electrical engineer during some down time during a long project in Canada. We started talking about residential AC power.
Reportedly in some multi tenant buildings in Canada the individual suites may be supplied with two phases from a 208 / 120 volt three phase system. I never got around to measuring the voltage from my dryer or range plugs in my condo before I moved into a single family home that has a 240 / 120 two pole / single phase supply.
