I don't think Kirsten & Michael opting to move to Oakville with Bruno and Meagan is too surprising. We've been waiting to find out which Gauthier/Marcotte teams might be moving to Oakville in any case. And it's already been discussed as a possibility that K&M might make the move for a few reasons (closer to home for Kirsten; and perhaps K&M wishing to be in a position of receiving dedicated attention as the top team, especially with Luba & Charlie coming aboard in Montreal and being a major focus for Gauthier). In the L&C promo documentary, Gauthier sings Luba's bendability praises, and he is obviously over-the-moon regarding their potential.
Added to that, as someone already mentioned, it's not really a switch since K&M were being trained by both Bruno Marcotte and Richard Gauthier. It's more like a necessary split decision they had to make, i.e., stay in Montreal with Gauthier, or move to Oakville with Bruno & Meagan. I always thought it likely K&M would move to Oakville, especially after L&C paired and Gauthier became their coach. Now, probably Meagan will take on some of the aspects of training in Oakville, that Gauthier previously provided in tandem with Bruno.
Agreed. What I'd like to know is whether Julie Marcotte will stay in Montreal, while still continuing to choreograph for K&M as well as for some of Gauthier's teams, as an independent contractor.
