Robin McBryde stretches over the try line

Canada soon reduced the arrears with a Jarred Parker penalty.

But the visitors continued to struggled with their discipline, and Jones took full advantage with his fourth successful penalty.

Welsh hopes were further boosted by Canadian indiscretion minutes later when Canada's Rod Snow was given a yellow card after an offence at a scrum.

And almost before the Newport prop had a chance to make himself comfortable in the sin bin, Wales crossed for their first try.

A surge down the right wing by prop Ben Evans laid the platform for McBryde to crash over for his first international try. Jones converted.

Wales should have been firmly in the driving seat, but some indiscipline of their own let Canada back into the match.

Gareth Llewellyn was sin-binned in the second half

Barker made no mistake from the three penalties awarded in just five minutes to bring his side back to within seven points at 19-12 at half-time approached.

At least Wales had the consolation of ending the first-half scoring as Jones landed his fourth penalty in injury time, but the players would have been disappointed not to have left the field with a greater lead.

It was certainly not the kind of restart Wales would have wanted when they were down to 14 men as lock Gareth Llewellyn was sent to the sin bin.

The ever dependable Barker slotted over the resulting penalty. Another one followed three minutes later as Canadian confidence levels continued to grow.

The dull kicking dual continued as Jones landed his fifth effort.

Quinnell made his entrance on 56 minutes and was given a standing ovation by a crowd of just 31,000.

Sonny Parker made some impressive breaks

But even the presence of the mighty number eight failed to inspire the Welsh troops.

Blistering counter-attacking runs from full-back Rhys Williams gave Wales some hope of adding to their try-count, but the stubborn Canada defence continued to hold firm.

But the decisive breakthrough finally came after 66 minutes.

Winger Mark Jones stretched the Canada defence as he headed towards the left corner.

Lock John Tait tracked him all the way, but Jones managed to flick the ball inside where centre Robinson was on hand to finish the job.

Stephen Jones expertly added the extras.

Canada ended the scoring with a drop-goal by scrum-half Morgan Williams, but all eyes at the end were on Quinnell as he said an emotional goodbye.
