Per the Skate Canada JGP selection document, Canada has picked up 2 extra dance spots: in Ankara and Bangkok
Okay, then... Canada was 3rd in line behind Ukraine & France to pick up additional spots.
USA has more than 7 junior ice dance teams (AboVes, Deych/Hu, Epps/Gilman, Ilin/Cain, Kouevi/Homawoo, Stapert/Korotcov are all on the ISP, plus Fischer/Fischer and Fugate/Fugate were sent to Egna Dance Trophy in Advanced Novice this winter, and Feige/Middlekauf are also junior age-eligible).
Italy has 6 teams that are still junior age-eligible who competed at Italian Jr Nationals and their top Intermediate Novice team is junior age-eligible - even if there is a split or two, chances are high that new partnerships will be formed and Italy will give all of those teams a chance with at least 1 JGP assignment. (Technically, Tali/Lafornara are still junior age-eligible, but we know they're moving up to seniors this year, lol).
Germany is going to certainly relinquish spots - they have 4 junior age-eligible teams on their Federal and Junior national squads for 2025-26 (Kruk/Eisenhaber, Kobor/Kobor, Hemcke/Sladkov and Salenbauch/Salenbauch). They do have some other dance teams that are junior age-eligible who may warrant JGP assignments. The German fed can be pretty cheap when it comes to using all of their JGP spots, but they have 1 men's spot at every single JGP, so they may bite the bullet and use all their JGP dance spots.
Ukraine - clearly not accepting additional spots during the reallocation process, otherwise they'd have picked up the Ankara assignment before Canada. They have Pidgaina/Koval, Rekunova/Fediankin & Tkachenko/Pesca who were on the JGP this past season & are still junior age-eligible. I'm not sure if they have any teams coming up from Adv Novice. They have 3 guaranteed pairs spots in Bangkok, but no men or women assigned to that JGP, so my bet is they relinquished their 1 dance spot there and kept the other 6 spots for their 3 junior teams.
France - They'll gladly take additional spots, just like Canada.
Canada - picked up 1 additional spot in Ankara & Bangkok.
Belgium - 1 spot in 6 events - they only have 2 junior age-eligible dance teams, so they'll give up 2 spots, for sure. Their women's spots are in Ankara & Baku; their men's spots are Ankara, Varese, Bangkok, Baku, and Abu Dhabi but they only have 1 junior age-eligible man; they don't have any pairs teams - they're assigned 1 spot in Riga & Gdansk, neither of which will be used; their dance spots are Riga, Ankara, Varese, Bangkok, Baku & Abu Dhabi. Seems clear they relinquished the Riga & Bangkok dance spots, which would have then been reallocated.
Switzerland - we know they plan on utilizing all 6 of their JGP spots per their own 2025-26 JGP Selection doc linked above.
Slovakia - well, they only have 1 junior team left since Vaclavikova/Morozov split and I'm not sure if they're even age-eligible. They (Stefanovova/Boeris) don't have an ISU bio. Presumably, they're relinquishing most of their JGP spots (Riga, Ankara, Varese, Bangkok, Baku & Gdansk), but they may have kept them if they have some teams forming or coming up from the novice level. They have 2 men at every JGP, 2 pairs teams at all 4 of the pairs JGPs (Riga, Ankara, Bangkok & Gdansk), and their women's spots are Varese, Baku & Gdansk; so it's hard to guess which, if any, of their dance spots they may have relinquished.
Japan - They do have 3 teams who scored 130+ at Japanese Jr Nats, so, theoretically, they could decide to use all 6 of their spots. Yoshida/Ogahara and Yamashita/Nagata had JGP assignments this past season and it looks like the 3rd team (Shibayama/Kimura) haven't competed internationally yet. Their JGP dance spots are Riga, Ankara, Varese, Bangkok, Gdansk & Abu Dhabi.
Soooooo...
JGP Riga - France - picked up 1 ice dance spot (Belgium)
JGP Ankara - Canada - known that they picked up 1 ice dance spot (Slovakia?), possibly 1 additional spot available for reallocation which would have gone to France
JGP Varese - no spots relinquished
JGP Bangkok - Canada - known that they picked up 1 ice dance spot (Belgium), possibly 1 additional spot available for reallocation to France (Ukraine or Slovakia?), any other additional spots would have not been reallocated
JGP Baku - no spots relinquished
JGP Gdansk - no spots relinquished
JGP Abu Dhabi - no spots relinquished
At best, knowing WHERE Canada picked up their additional dance spots, it seems pretty clear that France has also picked up 2 additional spots, possibly 3, but we won't know for sure until we see the individual JGP Announcements as the ISU starts publishing them.
