The Maple Leafs, who have not lost to the Wallaroos since 2014, proved too strong and precise in a fierce attacking battle at Allianz Stadium on Saturday.
All five of the Canadian tries came from the front row as the visitors' lethal strike proved too much for a much-improved Wallaroos side.
However, Joe Yap's Australian side will be encouraged that they have made huge strides since a 45-7 defeat to Canada in Ottawa 10 months ago.
But poor handling and the inability to bring exciting wingers Maya Stewart and Desiree Miller into the game cost the Wallaroos enough in the end.

The hosts were unable to contain the Canadian strike early, as hooker Sarah Klein and support McKinley Hunt succeeded in scoring the goal during the first ten minutes.
Hunt's finish came from a stunning 22 metres.
Trailing 12-0 less than a few minutes later, the Wallaroos had to dig deep to stay in the contest.
And they did.
Powerful winger Siokabisi Balu appeared to have nailed Australia's first try, latching on to a brilliant inside pass from Stewart, but the video referee was caught out earlier in the match.
There was no denying Tanya Nadine soon after when the Wallaroos administered a dose of Canada's own medicine with a rolling strike off a clinical line-out winner from Katie Liani.

Clyne's second try on the half-hour, again from a Canada strike, gave the visitors a 19-7 lead at half-time.
Hunt scored his second straight goal after halftime, giving the fourth-place Maple Leafs a 19-point lead.
Once again, the Wallaroos hit back. This time on a penalty kick, after Canadian winger Maddy Grant brought down a Georgina Fredericks pass that would have sent prop Brianna Hoy for a certain five-pointer.
Sadly, instead of capitalizing on their one-man advantage with Grant in the sin basket, Australia conceded the fifth try to find themselves 33-14 down.
Despite some impressive resistance in the final 20 minutes, the Wallaroos were unable to pull one back.
