I moved from Ontario getting 91/82 with square dtv lnbs and a 91/82 lnb holder. I now live in Alberta. In Ontario I would use the holder and aim at 91 and get 82 by default from the holder. This is not working for me in Alberta. I know my dish is big enough so what am I doing wrong?

different skew

1st, are you sure you are picking 91W from the 91W LNB ?

If you are, are you sure you have the Skew set correctly for the new location ?
A quick lookup using the 2 locations showed it requires a flip on the skew...

Ontario ---
Elevation: 31.3°
Azimuth (true): 181.5°
Azimuth (magn.): 190.0°
Dish Skew : 90.8°
Turn clockwise standing behind the dish

Alberta ---
Elevation: 22.6°
Azimuth (true): 144.4°
Azimuth (magn.): 127.6°
Dish Skew : 71.6°
Turn counter-clockwise standing behind the dish

I am using a non-swekable dish. This bracket is for non-swekable dishes, aim at 91 and 82 comes in without skew. This method doesn't seem to be working in Alberta.

The poormans bracket that you have will work fine from your new location ( assuming your dish size is of adequate size ) . Being farther up north you will have to lower the elevation . ( See dishpointer.com for exact coordinates).

Well, a quick google says that Ontario is at 86 degrees West, so you could point due south and the bracket could have the two birds about equal AZ distance and equal EL from the center-line of dish with no skew. Alberta at 114.4 degree W is going to need a bracket that allows you to set the two LNB at a little different positions relative to each other if you can't skew dish. Get one pointed right with the old bracket and see if you can't kludge something together for the other LNB. Separation between the two is likely to be roughly the same--but you might have to adjust both verti and horiz.

If the Dish itself is non-skewable. How about tilting the mounting mast so it's not perfectly vertical, is that possible ? That should give the same result as skewing the dish and LNB bracket...
The goal is to try and match the ARC in the sky...
Since before you were looking almost directly South thus looking at the relative flat part at the center/top of the Arc. Now you are West and need to angle onto the Eastern down-slope of the Arc. So it would be (by the dishpointer data above) about a 19 degree turn/bend counter-clockwise (from behind the dish).
