No it's not. I'm not buying these takes.
He's Canadian, and the family (growing up in Toronto) is probably more Jamaican than English, he just like Arfield, was able to take advantage of his heritage for his personal sporting gain, and there is nothing wrong with that!
Daniel has lived the majority of his life in Canada (albeit short), and you'e going to tell me he feels more English than Canadian? The older he get's and the longer he's there sure, but right now I'm sure he feels Canadian.
As for the family, his father spent majority of his life in Canada, going to high school, post-secondary, and working for several years in Canada. His mother albeit born in England spent majority of her life in Canada, going to high school, post-secondary, and working for several years in Canada. Both parents I'll assume are well into their 50's.
So that "feeling ish" is nonsense, and it's just down to opportunity that still presents itself. His story is no different from Jackson, or Hoilett. If England gave them the opportunity they too would've taken it. Jebbison is just being stroked softly by England right now till he becomes a phenom or irrelevant.
