In Lyall v. Whitehead the court denied summary judgment on a limitations defence because it would only partially dispose of the action. The limitations defence was not readily bifurcated from the merits. This gave rise to the potential for duplicative results and credibility issues:
 In an attempt to persuade me that partial summary judgment is appropriate the defendant relies upon the decision of Justice Myers in Mason v. Perras Mogenais, 2018 ONSC 1477 (CanLII) (“Mason”). Justice Myers held that discrete issues, like limitation periods, which do not overlap with the merits that are left for trial, are suitable for partial summary judgment motions. I do not read Mason to stand for the proposition that partial summary judgment motions are appropriate in each and every case that involves a limitation period issue. In Mason, partial summary judgment was granted in circumstances where the case was brought to an early end, in totality, against one of the defendants. In my view, that situation is more akin to a summary judgment motion than a partial summary judgment motion since the action was brought to an end against that defendant. That is certainly not the case here. As discussed below, the clear potential for duplicative results and major credibility issues in this case are outside the realm of what Justice Myers considered appropriate in Mason.
 I agree with the plaintiffs that, whether the action succeeds or not, the dominant narrative of the broader underlying claim concerns the defendant’s conduct as Estate trustee and whether he breached his fiduciary duties to the plaintiffs. Even if the partial summary judgment motion was successful, the matter would move on to trial with several other significant issues and claims in play which raises the legitimate specter of inconsistent decisions. The facts underpinning the allegations the defendant seeks to dismiss are too deeply intertwined with the facts underpinning the remaining causes of action. It is not appropriate to grant summary judgment in this type of situation.
 This case falls entirely within the ambit of cases discussed in Baywood and Butera. In this regard I am mindful of the reasoning in Butera, which makes it clear that a motion for partial summary judgment should be considered a rare procedure that is reserved for an issue or issues that may be readily bifurcated from those in the main action and may be dealt with expeditiously and in a cost effective matter. As stated in Butera, such an approach is entirely consistent with the objectives set out by the Supreme Court in Hryniak v. Mauldin, 2014 SCC 7 (CanLII). I entirely agree, and in any event, the decision is binding upon me.
 In my view, this is exact type of case warned against by the Court of Appeal in Baywood. In this case, credibility is extremely important. As stated in Baywood, voluminous affidavit evidence can obscure the affiant’s authentic voice. That has happened here. I received the evidence in a decontextualized manner and to make any findings on credibility in this fashion would result in fundamental unfairness in a way it will not likely occur at trial where the trial judge will see all of the evidence. Put another way, I cannot make credibility findings on the issues before me without also impacting the trial judge’s ability to independently assess the facts at trial. The trial judge’s credibility findings will be based on a set of facts broader than mine, but will also inherently include those that the defendant has put before me. They are not readily bifurcated from the broader underlying claim.
