My parents in the Dallas-Fort Worth metro had a Leyland that had the same issue after an ice storm. The branches never did bounce back to their original position leaving the tree looking misshapen and ugly. They eventually removed it. Wish I had better news to give you but hopefully/maybe yours will recover. Give it some time and then decide what to do after that time period has elapsed. That'd be my suggestion.

welcome to the world of up nort conifer growers ...

if it could recover ... it probably would have by now ...

otherwise.. we simply accept whatever as ma nature reorginizing and reshaping our plants ... sometimes.. she makes for interesting plants.. lol .. who needs perfect conifers.. lol ..

frankly.. i dont see much wrong with it .. since i didnt see it previously .. in tree time.. over the decades... the tree will act.. to use that additional sun in that area ... and somewhat even itself out .... but i doubt it wont be sprouting new branches or anything like that to fill in ...

all that said.. who might want to look at guy wires and stakes .. and all that nonsense ... either accept it for what it is now.. or just get rid of it ..

The root cause is probably the shade from the other trees around it.
