Canada try for an immediate response, but Scotland resist, win the ball back and Helen Nelson boots to touch.

This game is very much on.

What a tournament Evie Gallagher is having.

Player of the match with a ridiculous 36 tackles against Fiji, and now she's come up with a big try for Scotland.

They have started this second half really well. They need the next score though.

Superb build-up play. Helen Nelson, so strong in the carries. A wonderful try there - second World Cup try for Evie Gallagher.

Scotland need to keep it clinical and use the wind.

Canada halt Scotland's momentum by holding up the ball-carrier and winning a penalty of their own.

Head coach Kevin Rouet gives it large in the wee box he's sat in.

His mood turns quickly though - the lineout throw isn't straight.

Canada have given away an awful lot of penalties in this game, but are yet to receive a warning.

Sarah Bonar is dragged down at the lineout and Helen Nelson nudges the ball closer to the corner.

Fran McGhie races down the left wing and is only halted by a high tackle.

This time Helen Nelson's kick finds touch and Scotland are into the Canada 22.

Scotland wing Fran McGhie hasn't been in the game all that much today, but she shows what she's all about here.

She pins her ears back and blasts her way up to the Canada 22.

Scotland subsequently go backwards but win a penalty.

However, Helen Nelson's kick to touch is weak and hands possession back to Canada.

Canada have a mission - win the Rugby World Cup. They're a force to be reckoned with.

The benefit of having the wind at your back is shown immediately as Chloe Rollie makes huge territory gains for Scotland with a booming kick.

Andrew Cotter's dulcet tones are back on the TV and we are back under way.

Evie Gallagher is out of the sin-bin for Scotland.

How are you all feeling at home?

Thumbs up for a Scotland comeback. Thumbs down for you pessimists.

As soon as we lock in and get that momentum, it definitely helped us get and continue to get into the game.

Now that we have that scoring momentum, I think it'll help. When we have that quick ruck, it makes it hard to stop.

Scotland are getting in the right areas. There are opportunities for them.

Phew.

Scotland get through without further damage and will have the wind at their backs in the second half.

They are still just about in touch.

A huge roar from Scotland's pack after Canada knock on.

The clock has ticked past 40 minutes, so if they get through this scrum, that will be half-time.

Blessed relief for Scotland after a pass drifts forward from Canada full-back Julia Schell.

They have just under two minutes to get through to the break.

The first half-hour was fairly even, but Canada look to be moving through the gears.

Scotland need to try and get to half-time without any further damage and regroup.
