From the opening number, Body, by electronic duo Loud Luxury to the closing retro performance by Corey Hart, the 2019 Junos were a celebration of Canadian artists past and present — musicians currently climbing the charts and artists who helped lay the groundwork decades ago.

While In My Blood singer Shawn Mendes performed via video from Europe and scored the most trophies — he won five including artist, single and album of the year — it was Hart who had the audience on its feet.

Here are some of the most memorable moments from Sunday's Juno Awards in London, Ont.

Corey Hart Never Surrenders

It's no longer commonplace to see Hart, a staple on the 1980s music scene, take centre stage but it looked like he'd never left as he performed the smash hits Never Surrender and Sunglasses at Night.

Hart, who marked his induction into the Canadian Music Hall of Fame with a rare performance, had the crowd dancing and cheering as he took them back to the days of synthesizers and cassette tapes.

The singer might even introduce a new generation of listeners to classic tunes such as Boy in the Box and Everything in My Heart when he embarks on a Canadian tour in June.

Jessie Reyez salutes fans

Singer-songwriter Jessie Reyez, who has recently worked with major pop names including Dua Lipa, Eminem and Kehlani, encouraged her young fans to dream big.

"None of this is possible without your support," she said after winning a Juno for R&B/soul recording of the year. "I am you and you are me. And if there's one thing that you're chasing, and you're willing to work hard for, do it."

Reyez brought her parents and brother to the ceremony.

Sting's surprise appearance

Sting, who's currently in Toronto performing in the musical The Last Ship, received extended applause after making an unexpected stop on the Junos stage.

The Fragile singer introduced Canadian producer-composer extraordinaire David Foster, who received this year's humanitarian award.

Jeremy Dutcher makes dramatic entrance

Jeremy Dutcher, whose Wolastoqiyik Lintuwakonawa won the Juno for Indigenous music album, highlighted Edmonton-based Cree designer Luxx on the red carpet by wearing an intricately embroidered cape with Cree lettering and a nearly two-metre train.

Dutcher, who won the prestigious Polaris music prize in 2018, also gave a spine-tingling performance of Sakomawit from his album, which intertwines traditional Wolastoq songs with classical and electronic music.

Sarah McLachlan gets political

Host Sarah McLachlan, known for her ethereal voice and massive hits like Angel, Building A Mystery and Possession, sounded off — without naming names — about what's going on with "our neighbours to the south."

"You know when you live some place peaceful and beautiful?" McLachlan said on stage during her opening monologue.

"Then you get a crazy neighbour, and they start causing all sorts of trouble like putting up weird walls, picking fights with all the other neighbours, telling your daughters how they should behave, all the while saying they're making the area great again and you just watch feeling helpless. And hope that they'll be gone by 2020."

McLachlan did double duty, not only hosting but also performing during the event alongside folk-rock band Whitehorse. She sang Beautiful Girl and In Your Shoes, from her 2014 album Shine On.
