Is an assessment report to be used on a motion to change the status quo at trial?

Perhaps on the other hand, in J.D. v. N.D., 2020 ONSC 7965 and again in Jonczyk v. Tilsey, 2021 ONSC 2546, albeit both parenting cases, MacKinnon J. addressed the use to which assessment reports may be put on a motion. She suggested that the previous case law, that an assessment report is to be used at trial, and therefore that a status quo would not normally be changed prior to trial based on such a report, may have softened.

I also note that MacKinnon J. cited ¶ 32 of the decision of Chappel J. in Matsinda v. Batsinda, 2013 ONSC 7869, wherein Chappel J. said that the caution surrounding the use of assessment reports on motions applies primarily to their conclusions and recommendations, rather than the facts, observations and other evidence set out or summarized in the report. The underlying summaries of the evidence may be of considerable value to the motions judge.
