Speaking afterwards, man-of-the-match Toner said: "It was my first cap for Ireland 'A' so I'm pretty happy. We have been together a week now and that showed at the end when things came off.
"We gave away a lot of penalties and their kicker (Monro) was on form but we improved and are happy overall, especially given the conditions."
Livewire scrum half Isaac Boss, who captained the Irish on the day, said: "We were a little bit rusty at the start but we pulled out a win. Credit to Canada, they made it tough for us and are a quality international side.
"Now we are looking forward to the next game against Georgia and trying to qualify for the final."
Ireland 'A', coached for this tournament by Declan Kidney and Ireland's Grand Slam-winning management team, will play the Georgians at Infinity Park in Glendale, Colorado on Sunday (kick-off 3.30pm local time/10/30pm Irish time).
