The 22-year old striker, born in New York, spent a year with the Toffees experiencing the rigours of life as a professional footballer in the UK but admits it is nice to be back in more familiar surroundings and closer to family and friends.
"England is definitely a place where you have to stick through it and really want to be there," Arnoux told the Vancouver Sun Whitecaps training session. "I just couldn't take another year of being by myself, with all my friends back here.
"I just think it was the right move for the person I am - to be back around people I know and trust. It was just time for me to come back home."
Arnoux trialled with English Leauge One club Plymouth Argyle after his stint with Everton but said as soon as he heard about the Whitecaps opportunity, his ears pricked up.
"After the Plymouth experience, I told my agent I didn't want to be [in England] and asked if there was anything of interest back home," Arnoux added. "He brought this [Vancouver opportunity] up and I'd heard it was a great organization with great people and I definitely wanted to be part of that."
Arnoux's future with Vancouver is uncertain as the expansion franchise is set to enter MLS next season and he may have to go through a draft or weighted lottery to find a new home.
But he admits he hasn't thought too much about it at this early stage.
"I honestly couldn't tell you anything about it," he said. "I've read some stuff on the Internet about that but I don't know how it works. I'm just playing and kind of just seeing what happens at the end of the year and hoping for something."
