Canada will put their best skaters in the SP
Maddie
Stephen
Piper and Paul
Deanna and Max
then, if they qualify for the LP
Maddie and Stephen have to skate for sure.
But depending who else qualifies and how close it is, Canada may bet on keeping Piper and Paul as well as Deanna and Max for the long programs. Italy has a strong pair and dance team and Canada needs to pass them to earn a medal. Georgia has a strong pair too and their dance team is good but not as strong. Canada could use LaLa there and still be ahead of Georgia but would lose to Italy. So it will depend on scores.
Of course, considering Trennt and Lia are "usually" better jumpers and that the axel sequence is a 10 point element and crucial in the Long Program, they could be chosen for the LP but I doubt they would place ahead of either Georgia or Italy, unless these made major mistakes. They just do not get as high PCS internationally.
So if we had to decide in the dark right away, I'd say Canada would only use 1 entry per discipline this time around. On paper, if everyone skated well, that would be their only shot at a medal. However, it will be interesting to see how the points are distributed after the SP to see if Canada has the option to give an opportunity to their other entries.
