Is there a Big Data / NLP / Machine Learning scene in Vancouver? I rarely see any Data Scientist positions being advertised in Vancouver?

I am a foreigner with a PhD in applied NLP from a US university and I have been looking at such positions in other tech hubs like Vancouver, Montreal, Berlin, etc.

But these types of jobs only seem to be in the Valley. I work in the Valley and I like it here but I want to move to a place where I can have a stable immigration situation.

US immigration may be cumbersome but the most interesting jobs in Big Data seem to be in the US.
