The 21-year-old Canadian defender has returned to his home country on a season-long loan from Scottish club Rangers.
Aird arrived in Glasgow as a 16-year-old in 2011 before forcing his way into the first team at Ibrox during the 2012/13 season in Scotland's League Two.
The once-capped Canada international was a regular part of the League One title-winning team of 2013/14 but has since found frequent football hard to come by with just three substitute appearances going under Mark Warburton this season.
Aird will now spend the 2016 MLS season with the Whitecaps and is looking to get his career back on track in a more familiar environment having grown up in Toronto.
"It was a few factors," Aird said via a conference call.
"I found myself not being involved as much as I'd like to be. When the new manager came in, the team was doing well and he was just sticking to the same lineup, as managers seem to do.
"So I just thought that it was in my best interest that I needed to go and get regular games in."
And Aird will use his stint in Vancouver as a chance to press for selection in the Canadian setup.
"I think wherever I went out on loan, as long as I'm playing first team football then hopefully I'm in with a shout," Aird added.
"I've got my foot in through the door, being in the last two camps and getting my first cap against Ghana. But hopefully playing more regularly over here they get to watch me a bit more and hopefully I can cement my place in the squad moving forward."
