Answer: The distance in a straight line (as driving distance would be near impossible to plot) is 5200 kms. That Nova Scotia has the 45 parallel running through it means that this would be 1/2 the distance to the North Pole from the Equator or 5200 kms from Nova Scotia to the North Pole (being the 180th parallel.)
Answer: 460 mi - about 7 hours 10 mins driving time.
