Halfway between the North Pole and equator isn't where you think it is

During wintertime in Montreal, it's easy to think that we live in a northern part of the world. It's cold, it's snowy and it's dark at 4:30 p.m. But surprisingly, Montreal is at nearly the exact halfway point between the North Pole and the equator.

If you have a globe near you, take a closer look at it.

At the equator, this is 0. And going further north of the equator, this number gets bigger, until we reach the North Pole at 90 N. This number is called a location's latitude.

Here's a few example cities and their latitude:

What is Montreal's latitude? Almost halfway between 0 and 90, with a latitude of 45.5 N.

It's natural to assume the halfway point would be anywhere at 45 N latitude.

But to find the exact halfway point, there's a problem: The Earth is not a perfect sphere. It's slightly squished at the North and South Poles. What this means is that the true halfway point is about 16 kilometres north of 45 N latitude.

The exact latitude is 45.1433 N.

Still have your globe nearby? Try to find 45 N on it. You'll notice there's not any one single point, but rather an almost limitless number of places that could be the halfway point. You can imagine placing a piece of string on the globe at 45 N and any spot on that string could be the halfway point.

I wanted to find a spot that was south of Montreal, accessible and visually interesting. And I found one: at the crossroads of a place called Aubrey, Que.

On Google Street View, I saw a mailbox under a patch of trees, and a few houses dotted along the road of what appeared to be a farm-focused part of the province.

So I got into the car and began driving.

There was no sign marking this spot. That was expected. I saw mailboxes, trees and houses lining the crossroads.
