He joined in 1941-1943 (one source said with 16, another said the volunteer unit was founded afterwards), there is quite a lot of evidence that Ukrainian volunteer troops in that time did partake in the Shoa, in “anti-partisan” actions and also genocides against polish and others.
Nationalists did try to diminish those facts, or did blame other units.
I knew they would use the commission which did actively walk back from the Nuremberg decision - based on a ton of evidence - to declare the (Waffen-)SS a criminal organization due to its part in the Holocaust and Shoa.

To name just two.
The commission was a really fucked up thing, too. It didn’t look into Nuremberg archives, didn’t acknowledge scholarly work, it didn’t ask neither Eastern Europe nor the Soviet Union for information or access to archives.
After the commission ended more empirical scholarly work was done which also strengthened the link between Galicia members (and sometimes even before they joined that unit) to war crimes and worse.
CW One of the commission consequences
As a result of the Deschenes commission, the Criminal Code was amended in mid-1987 to allow the trial of suspected Nazi war criminals living in Canada. In December of 1987, charges were laid against Imre Finta. (See also Finta Case.) Finta was the first Canadian to ever be prosecuted for war crimes under the new amended Criminal Code. He was accused of forcibly confining over 8,600 Jews in a brick factory located in Szeged, Hungary, in 1944, from which they would then be sent to the Nazi death camps at Auschwitz and Stasshof. Finta was ultimately found not guilty, and no further war crimes trials of Nazis or Nazi collaborators were ever held in Canada afterwards.
The jury was stacked and his involvement in the Holocaust clear: https://journals.lib.unb.ca/index.php/unblj/article/download/29656/1882524838/1882525145
“Both the appeal and the cross-appeal were dismissed by the Court by a narrow margin of 4:3.”

Canada did not even sentence people when there were 6-19 eye witnesses of their participation in the Shoa - without threat to their lives. Don’t give a fuck about the commission.
