Hey there, time traveller!

Parts of southeastern Canada are no longer under a heat warning today but a large stretch of the country will continue to see scorching temperatures.
Environment Canada says some parts of Ontario and Quebec, including Ottawa and Montreal, could see daytime highs near 30 C and a humidex of 35 to 40.
It says the heat warning also applies to parts of Eastern Canada, including much of New Brunswick, Nova Scotia and Newfoundland and Labrador.
Southern areas in the Northwest Territories are also under a heat warning, and could see temperatures up to 30 C with overnight lows near 15 C.
Some areas in southern Ontario, including Windsor and Toronto, were also under a heat warning but the weather agency had lifted it as of Thursday morning.
As with any heat warning, it is recommended that people watch for the early signs of heat exhaustion and check in with vulnerable family and friends to ensure their well-being.
