Well, here's the link to their
ISU bio, which gives a little bit of information.
She is new to pairs, having been a singles skater up to this point (11th in juniors at Canadian nationals earlier this year). They were paired up earlier this year.
Their result so far here is not a complete surprise, because they have done well at their summer competitions. For example, their short program score at Indy was 47.68 and their long program score was 86.07 (competing in senior). In fact, their summer competition results have been the best of any of the Canadian JGP-eligible pairs teams.
Given their inexperience as a pairs team, I don't expect them to win here, but if they skate as they have at their summer competitions they can certainly medal.
One encouraging thing about this team is that Kaleigh can do the triple toe and appears to be close to having a 3S (
Protocols from Summer Sizzle singles long program).
