Bostock insists he can still make it to the top of the game.
He said in the Sunday Mirror: "All I want to do is play. First team football is everything.
"I know some people might think I am one of those players who is in the cash comfort zone and drifting.
"But that is not me. My contract at Tottenham is up in June and that is when my loan spell is over. We will have to look at things again then.
"My hope is that I will improve by playing here in Canada. I am only 21. There is still time for me to achieve what I want."
