Not weird. Ukranian immigrants have historically formed a huge component of Canada. It's much easier to intake culturally prepared populations.
For example: my family came here from Melitopol, albeit there generations ago. Currently it is Russian occupied territory. I'm emotionally invested in its reclamation in a way that I wasn't in regard to Syria.
You're trying to make this a racism thing. It's a cultural thing. If the UK was being invaded and we took British refugees in higher numbers, it would be similar.
That said, I am pro-intervention in both cases. I think NATO should just join the war in Ukraine, and I think a coalition should intervene in Syria. We have these hats that people wear on Remembrance Day with "Lest we forget" and a poppy, but it appears we've forgotten. Nuclear threats are just threats.
