Aird’s hour long performance in the 5-1 win over East Fife at Murray Park saw him set up three goals for the home side before being withdrawn.
As he left the pitch he drew praise from McCoist and his coaches who had watched the midfielder’s performance at Auchenhowie.
And Wilson later confirmed that the Rangers boss had added the attacking youngster to his squad for tonight’s Ramsdens Cup tie with Queen of the South.
He told RangersTV: “Fraser came over from Canada but he’s a big Rangers fan and his whole family are fans of the club.
“He’s a Scot through and through despite that accent and he just loves the club. He’s had to deal with that because it can be a difficult situation for a young player.
“Playing for the club you love can be awkward but he’s handling that now and he’s been called in to the first team squad and I’m delighted for him.
“I wasn’t expecting it because I had spoken to the manager before the game and he mentioned one or two that he was thinking about.
“Fraser must have been in the back of his mind and I think his performance has done it for him.
“That’s the beauty of having these games here at Murray Park where the manager is here to see it against good opposition, because for half an hour it was a ding-dong battle.”
While it remains to be seen if Aird makes the 16-man match day squad, Wilson feels the step up to part of the first team group tonight has been earned by the midfielder, who he believes has shown the desire and commitment required to catch the eye.
He added: “Fraser loves his work and that’s really infectious. He has a great appetite for things and that reflects in his play.
“He comes in to training every day and he’s one of the first you hear in the dining room, the dressing room and out on the pitch.
“Sometimes you don’t know if you’re ready until you’re pitched in but he’s certainly worked hard enough and is physically strong enough.
“It’s different when you go out in front of 50,000, and the likes of Barrie McKay and Lewis Macleod have shown that they can cope with that.
“I’m sure that Fraser will handle it, but I think that the manager is taking him along for the experience. I don’t know that he’ll feature that much but if he does that’s great for him.”
