Which provinces are below the US Border?

Answer 1

thanx for the fun question

but do you mean which Canadian provinces extend at all southward of any part of the usborder

if so then indeed all the provinces & all the territories as well are below all or most of the Alaska portion

but if you mean at all southward only of any part of the lower48 portion of the usborder

then all the provinces still qualify but not the territories

& if you mean at all southward only of the distinctively long straight 49th parallel segment of the usborder then indeed all 10 provinces again qualify tho the 3 prairie provinces do so only by the skin of their teeth

& if you mean which provinces lie south of the 49th parallel in their entirety then only nova scotia & new brunswick & pei qualify

& if you mean which provinces are situated entirely on the American side of the usborder then none because all the provinces on that side are called states & are really not provinces at all

but if what you mean by below is just in terms of altitude above sea level rather than latitude or position relative to a line then because the usborder is everywhere above or at sea level & Canada extends below sea level only in a tunnel or 2 in british Columbia then only bc is anywhere at all below the entire usborder

& finally

if what you mean by are

is

are ever at any time

rather than

are permanently

well then

thanx to local tidal differences

parts of all but the 3 prairie provinces & Ontario are indeed sometimes below the entire usborder

oh & one more thing i nearly forgot

the lowest parts of all the provinces & territories are always below the highest parts of the usborder where it crosses the rocky mountains

of course
