“Mr. Spencer acknowledges that Ms. Spencer is and has been a good parent. Ms. Spencer’s evidence is that the children were doing well with her after separation and had adapted to the routine that the parties had put in place. This is not disputed by Mr. Spencer. Accepting, as I do, that Mr. Spencer has been a good and caring parent, nevertheless on an interim motion where there is evidence that the children are doing well, the court is inclined to maintain the status quo in the absence of convincing reasons to the contrary. The court should be careful not to further disrupt the lives of the children by a major change in their lifestyle at an interim stage.”
