Former Canada defender Wilkinson said her players “absolutely rose to the occasion” against opponents ranked 24th in the world by Fifa, eight places higher than Wales.
“I think every game we’ve played this year has been against teams that are ranked higher than us,” she added.
“But we’ve been going toe-to-toe for a while now and knocking on the door, and this was the performance we needed, especially at the end of a tough year.
“Everyone’s brought up our recent string of results and I understand that, but equally you can see that this is a team that is almost unrecognisable, I would say, because of how confident they are on the ball.
“This is a really good team and, as soon as they start believing that, I think we’ll be in a great spot.”
Wales return to action in March, when their bid to qualify for the 2027 World Cup will start with a trip to the Czech Republic and a home fixture against Montenegro.
They will also face Albania in Nations League Group B1, which doubles up as the first stage of World Cup qualifying.
