He served in the 14th Waffen-SS Grenadier Division, a voluntary unit made up mostly of ethnic Ukrainians under Nazi command.
From the linked Wikipedia:
The 14th Waffen Grenadier Division of the SS (1st Galician) is today honored by many Ukrainian nationalists.[58] Since 2010 every year on 28 April a march is held to celebrate the foundation of the division.[59] In addition streets were named after the division in Ivano-Frankivsk (Ukrains`koi Dyvizii Street) and Ternopil (Soldiers Division "Galicia" Street).[60]
On 23 September 2020, the Ukrainian Supreme Court ruled that symbols of SS Division Galicia do not belong to the Nazis and therefore were not banned in the country. The same argument was made by the Ukrainian Institute of National Memory, led at the time by Volodymyr Viatrovych.[61]
None of this is a good look for either Canada or Ukraine. They were voluntary Nazis, voluntarily killing Jews, Poles, Slovakians, Yugoslavians and Soviets towards the end of the war as Hitler was getting destroyed. And as late as 2020 the Ukrainian government was giving them a huge pass. As though a Waffen-SS division supported by Himmler was... not Nazi. How on earth this MP or his staff did not do a cursory google of the guy is still beyond me.
