The Canadian international impressed with his energetic displays on the right flank, playing a key role in Canada's progress to the last 16.
He is the only Canadian to be included in the star-studded XI, which features football superstars Lionel Messi, Kylian Mbappe, and Erling Haaland.
Johnston's performances helped Canada reach the knockout rounds on home soil, where they are set to face Morocco.
His inclusion comes despite a controversial moment in the opening match against Bosnia and Herzegovina, where he narrowly avoided a red card.
The Canadian defender lines up in a back four alongside Mexico's Israel Reyes, France centre-back Dayot Upamecano, and Germany's Nathaniel Brown, with Egypt goalkeeper Mostafa Shobeir behind them.
Further up the pitch, Brazil's Bruno Guimaraes anchors a diamond midfield featuring Michael Olise, Messi, and Vinicius Jr, with Haaland and Mbappe leading the attack.
Johnston's recognition in the team of the group stage underscores his growing reputation on the international stage, highlighting his importance to club and country.
