Wales are looking for a first win over Canada in 17 years
Gillian Boag try, Sophie de Goede con
It was coming and there it is - Canada's fifth try.
The hooker dives clear of a lineout drive that was set up by Sophie de Goede's catch - and that should be the game.
Canada 28-17 Wales
Fly-half Robyn Wilkins is done and replaced by Lleucu George.

Jasmine Joyce tries to take it out of her own half but Wales are penalised again. This is getting ridiculous and I wouldn't be surprised if there's a card coming soon.
Canada 28-17 Wales
Big steal by Wales. Canada had the lineout and were looking to get the rolling maul going but someone snuck in and pinched it - I think it was Kate Williams. Huge play.

It's definitely a point in the game that Wales need to score next to stay in the game.

Oh Canada waste another chance. From a scrum five metres out, it looked an easy pass for Sophie de Goede to charge at the line but the ball is fumbled and Wales escape again.

It feels both teams are running out of ideas on how to get the upper hand.

Georgia Evans returns and is on for Abby Fleming. So Kate Williams stays on.

Wales have just conceded their 12th penalty... compared to Canada's six.
That suggests only one winner.

Georgia Evans has just run past us in our media box.
Great to see no serious damage after what looked like a nasty clash of heads with the Canadian scrum-half.
She's passed her HIA and I'm hearing she's going to return to the field.

Lisa Neuman carries hard but yet again Wales are penalised at the ruck.
They have to sort that area out to have any hope of winning this game.

You depend on the leadership within the group now to say 'this isn't working, what do we do next?'
The likes of Alisha Butchers, Kerin Lake and Hannah Jones need to set that leadership tone and you depend on them now to change the momentum.
Canada 28-17 Wales
Changes for Canada with hooker Gillian Boag and Krissy Scurfield on.
Surprised to see Florence Symonds go off.

Wales need a try, it will up the gear, Canada are reading Wales well now.
Wales need to change how they are playing at the moment.

Hooker Kelsey Jones and back-row Sioned Harries are on for Wales.
Carys Phillips and Bethan Lewis' games are done.
Canada 28-17 Wales
Poor handling by Canada gives Wales a lineout and a lovely short pass by Keira Bevan sends Lisa Neuman trucking it down the right wing.
But again Wales are penalised at the breakdown for hands in the ruck.
Frustrating.
Canada 28-17 Wales
Jasmine Joyce counter-attacks from a Canada kick but second-row Abbie Fleming infringes at the ruck and Wales have to hand back possession.
Canada 28-17 Wales
Wales managed to respond quickly to Canada's tries in the first half, they need to do the same again here.
