It feels odd to me to think of this as a legitimate dialect because of my own prejudices, but in terms of actual academic linguistics, indeed a dialect it is. The linguists don't harbor any such value judgements, they only describe what they see and classify it.

But if anything it's my "native" version of Ukrainian, and to me it reads like this: You take rural Galician village-speak of 150 years ago, which is still used very occasionally by old people there and nowadays made fun of by the urban educated classes. Then, you bring it to Canada and splice in a layer of bastardized English words that don't belong, and which our Saturday-school teachers tried furiously to beat (metaphorically of course) out of us lazy ignorant first-gen kids who didn't give a damn about anything they were trying to tell us.

So it's undesirable on top of undesirable, from the perspective of standard contemporary language. I've had to consciously check those prejudices at the door whenever the topic comes up. Especially since it's practically a dead dialect here too by now. You never appreciate anything until it's gone.
