It won't be a hurricane, they only exist in tropical regions. They are known
as extratropical cyclones (with maybe hurricane force winds?) but the cold
water of the Grand Banks will likely ensure that it'll have long run out of
puff.

More likely it'll get caught up in the jetstream and get absorbed in some
depression or another in the Atlantic...

Warm-core tropical cyclones do make it all the way to the waters off the
east of Canada from time to time. "Fabian", for example, was still a
genuine hurricane when it crossed 45 deg N earlier this month. North
Atlantic hurricanes are often found outside of the tropics. Indeed, it's
not unusual for them to form outside of the tropics.
