Wanyama left Spurs last month for Canada.
"I have come here to find my happy place again, playing football," Wanyama told the Daily Mail. "I love Spurs but it was tough. I was a long time injured yet I came back stronger.
"I never gave up, even if I wasn't in the team, but I kept getting told I'd get my chance. What frustrated me was I worked hard to get fit and, if I wasn't selected, I'd ask to play in the U23s to get sharpness but would be told 'no'. It was as if I was a fragile egg. So, even when I got some games, it was difficult to be at my peak as I'd had so little minutes in preparation.
"Poch is still like a father figure to me. He played a big part in my game but why he chose to do what he did I don't know. Maybe it was down to others above him."
