Aldcroft, who started her rugby career with Scarborough RUFC's minis, won her first full cap for England in the USA last month and will now look to impress in the Under-20s in a bid to retain her place in the senior squad.
Under-20s head coach Jo Yapp said: “It has been great to have the players in camp in preparation for these three tests and we are very excited to them perform on Thursday.
"We are expecting a strong Canadian side which will be a great opportunity for us to see how our players step up to the challenge.”
