ARTCC Great Lakes HI / LO Sectors 2025

[leatherheadstudios]

This is a chart I made for my reference in monitoring. Data has come from many sources, including 2 years of monitoring and tracking ADSB data and a lot of help from the RR Community.
It is not 100 percent accurate. If you use this chart for real world navigation, you will likely fly into a mountain or meet the folks who drive F-16s, A-10s or the like. Hope this helps your listening enjoyment.

Amazing that US FAA cannot enforce a complete SOP center policy giving compliance to sectors info on lat/log like ZOB or anyway we're in the FAA, like to see Canada Airnav to follow with there SOPs, wishful thinking.

Nice work on the charts. I do see some discrepancies though with Toronto and Montreal that you might want to take another look at. I'm familiar with both areea and have confirmed all frequencies recently.

High Altitude



Low Altitude



I also see some disrepancies with Minneapolis, Boston, and Chicago I'll post later. Cleveland looks good.

Glad CLE ZOB looks good, my monitoring area!!!

Great stuff, Keep em coming, I will update as I receive the corrections. I went as far as I could with the info available, now with some local knowledge I can fine tune this mess and we can really have something.
Thanks for the feedback.

Great stuff, Keep em coming, I will update as I receive the corrections.

A few more tweaks for TORONTO.

TORONTO HI

The WIARTON LO shelf that is AOB FL230 should be on the LO chart.

Change boundary line to solid between PICTON HI and BARRIE HI

Delete LO boundary hashed lines.



TORONTO LO

ZYZ LONDON LO AOB 11000

ZYZ KITCHENER LO 12000 - FL230 above LONDON LO

ZYZ KITCHENER LO 7000 - FL230 above WEST SATELLITE LO

EAST SATELLITE LO missing, 133.400 [Toronto]

119.700 {Hamilton] to EAST SATELLITE LO

Although personally I would delete the WEST SATELLITE LO and not add EAST SATELLITE LO to reduce clutter on the chart.

Change remaining hashed sector boundary lines to solid lines.

Add WIARTON LO shelf AOB FL230 with hashed lines.
