The Clarets midfielder, who qualifies through his Toronto-born father, replaced Tosaint Ricketts in the 46th minute as Mexico ran out 3-0 winners in front of a 54,798 crowd - a record for a Canadian national team in any sport - at the BC Place Stadium in Vancouver.
And despite the result, Arfield, who had represented Scotland at under 19 and under 21 level and he won a Scotland B cap in 2009, enjoyed making his debut in front of so many fans.
He told theprovince.com: "It was an absolute pleasure for me to play in front of so many fans (Friday). It’s something that will live long in my memory.
"In footballing terms, it was an absolute eye-opener. How they play, their movement. When you give them one yard it seems like it’s five or six.
“They were a fantastic counter-attacking team, a lot of power and pace up front, and the movement from Chicharito at times is incredible.
“You take so much pleasure and so much experience from 45 minutes like that."
Scott becomes the second Claret, after David Edgar, to appear at full international level for Canada, and he will become the 70th player to be featured on the Burnley FC international honours board here at Turf Moor.
He joins fellow internationals Sam Vokes, Stephen Ward, Michael Duff and Danny Lafferty, whose names are also on the board, together with George Boyd, Joey Barton, Fredrik Ulvestad, Matt Gilks and Paul Robinson whose caps were won before their time at Turf Moor.
Scott’s name will be added to the board very shortly.
