[5] On February 22, 2017, Charlie Puth was announced as the opening act for the North American leg of the tour,[6] and Rock in Rio announced Mendes as a performer of the festival in Rio de Janeiro.

[7] In a concert review from London Evening Standard, Matilda Egere-Cooper praised his vocals and his ability to make the concert enjoyable and meaningful at the same time, while writing, "he's got a lovely, soulful voice, reminiscent of Justin Timberlake, with a few dashes of Ed Sheeran.

The second came at the end of the show on Treat You Better, which eventually descended into the hand-clapping slab of pop brilliance it's known for."

[8] Ryan Potter from Toronto Star wrote, "Mendes really did perform like this was an all-or-nothing show for him, not just month four on a nine-month world tour," while also noting how Mendes is still the same eager crowd-pleaser he was the last time he played the Air Canada Centre, while giving the show 3 out of 4 stars.

[9] Sadie Bell from Billboard praised his "seamless transitions from acoustic and electric guitars to piano, along with his impressively consistent vocals and high energy."
