Defeat for Italy would be their third straight loss at the World Cup and their worst run of form at the tournament since losing four in a row between 1999 and 2003.
Canada conceded eight penalties in their opening-weekend defeat by Ireland, while Italy shipped 19 against France.

Pool B
South Africa vs Samoa
at Villa Park, Birmingham
Stadium capacity: 43,000
Kick-off: 16:45BST
South Africa coach Heyneke Meyer says captain Jean de Villiers is the right man for a World Cup game "the whole country depends on" against Samoa.
Centre De Villiers, 34, has won 109 caps and skippered the Springboks in the 34-32 defeat by Japan, a result Meyer apologised to his nation for.
"It was one of the most difficult decisions of my life," said Meyer, who has made eight changes to face Samoa.
Tusi Pisi is replaced by Mike Stanley at fly-half in Samoa's key alteration.
Teams
South Africa: Willie le Roux, JP Pietersen, Jean de Villiers (captain), Damian De Allende, Bryan Habana, Handre Pollard, Fourie du Preez, Duane Vermeulen, Schalk Burger, Francois Louw, Victor Matfield, Eben Etzebeth, Jannie du Plessis, Adriaan Strauss, Tendai Mtawarira.
Replacements: Schalk Brits, Trevor Nyakane, Frans Malherbe, Lood de Jager, Siya Kolisi, Ruan Pienaar, Pat Labie, Jesse Kriel.

Replacements: Ole Avei, Viliamu Afatia, Census Johnston, Faifili Levave, Vavae Tuilagi, Vavao Afemai, Tusi Pisi, George Pisi.
Match stats
This will be the fifth World Cup Test between these nations; the Springboks have not faced any other side more often, although they have also played England four times.
The first three meetings between these teams at the World Cup saw an aggregate winning margin of 130 points for South Africa, but they defeated Samoa by just eight points in 2011.
The Springboks are enduring their worst calendar year in the professional era having lost four of five Test matches in 2015.

Pool A
England vs Wales
at Twickenham, London
Stadium capacity: 82,000
Kick-off: 20:00BST
Much of the country is expected to come to a standstill tonight to watch this game between two huge rivals at the home of rugby union
England and Wales are to face each other in what is expected to be the most explosive contest of the World Cup so far, as both sides aim to bolster their quarter-final chances.
About 82,000 fans will descend on Twickenham for the 127th game in one of rugby's oldest rivalries.
England have won the last two meetings since being
thrashed in Cardiff two years ago.
The loser will likely need to beat Australia to reach the knockout phase.
Both countries have begun their campaigns in Pool A with a victory, but this match is considered the biggest encounter in the early stages of the tournament.
England's win over Fiji in the tournament's opening match on Friday peaked at 9.4m UK viewers - the largest sport audience this year - and between 10m and 15m are expected to tune in for Saturday night's game.
"For us as a nation, this is the biggest game we've had for a long time against England," said Wales coach Warren Gatland, whose
injury-hit side will be cheered on by about 20,000 visiting fans at Twickenham.
Counterpart Stuart Lancaster has described it as the biggest match of his coaching career, and admits that
"if we lose I will be questioned".
His ultimate aim is to
guide England a repeat of their 2003 success when Jonny Wilkinson's dramatic drop-goal saw them become champions for the only time.
England: Mike Brown; Anthony Watson, Brad Barritt, Sam Burgess, Jonny May, Owen Farrell, Ben Youngs; Joe Marler, Tom Youngs, Dan Cole, Geoff Parling, Courtney Lawes, Tom Wood, Chris Robshaw, Billy Vunipola.
Replacements: Rob Webber, Mako Vunipola, Kieran Brookes, Joe Launchbury, James Haskell, Richard Wigglesworth, George Ford, Alex Goode.
Wales: Liam Williams; George North, Scott Williams, Jamie Roberts, Hallam Amos; Dan Biggar, Gareth Davies; Gethin Jenkins, Scott Baldwin, Tomas Francis, Bradley Davies, Alun Wyn Jones, Dan Lydiate, Sam Warburton (capt), Taulupe Faletau.
Replacements: Ken Owens, Aaron Jarvis, Samson Lee, Luke Charteris, Justin Tipuric, Lloyd Williams, Rhys Priestland, Alex Cuthbert.
Match stats
England are aiming for three straight victories over Wales for the first time since 2011.

In their last three defeats against Wales (2011-2013), England failed to score a try. However, England have failed to score a try just once in their past 15 Tests.
Wales have scored a try in each of their past 17 World Cup games - only New Zealand (20) have recorded a longer run.
