We can help with a look at actual charts used in air navigation.
This page from NavCanada:
....is an index for the High Altitude Enroute Charts for Canada, and part of the Arctic. We only need to refer to "HI" charts, since all flights
forming contrails will be above about 25,000 feet.
You can see that both HI 3 and HI 4 cover the Saskatchewan Province. It is actually one paper chart, printed on both sides. You can purchase one for
yourself for $12 from NavCanada direct on their website.
As it turns out, as I searched for these for you, I've found there is an entire sub-culture of "AvSim" fans out there....aviation enthusiasts, Private
Pilots, etc who are wannabe airline pilots.....they fly simulated airline flights, and have clubs and online chat, etc. Anyway, they use charts, same
as actual flights would. Difference is for simulations, the charts can be out of date.
Here is just one website: joomla.czul.info...
There you can select HI 3 and HI 4 for free download.
If you were in the USA would be easier, there is a great site to access this info: skyvector.com...
The owner of SkyVector wrote this in 2010:
I have written and called NavCanada many times asking for permission to scan an publish their charts online, under a paying licensing agreement.
Each time their response has been, "Not now, maybe later"
If you're a Canadian Citizen, perhaps you could write your lawmakers asking them to consider the safety benefits of easy access to accurate
Perhaps one day......
When you look at a downloaded chart, just find your location on the ground, then see the actual published Airways that pass overhead.
Additionally, next time you see contrails oriented North/South, you can go to this link on FlightAware, it is centered on the airport at Saskatoon:
Flightradar24 might also work, but I just now looked and it isn't working properly (probably why some people claim they check, and don't see the
airplanes that are in the sky live). When I looked, the entire USA was blank of airplanes. We all know that is not true, at midday.
