Welcome! Lots of 767s cross the Atlantic (and the Pacific) every day. Absolutely nothing to worry about.
There are smaller planes used for transatlantic service as well - AC flies Airbus A319s on its YYT-LHR route. Despite crossing an ocean, that flight is shorter in time and distance than LAX-JFK for example. BA operates A318s on LCY-JFK. And then you have a lot of small, private jets that cross as well

Not anymore. AC used to fly them YVR-HNL-SYD, but it went non-stop once they acquired 777s.
