In Bowen v Rengro Ltd., Master Dash provides a useful, and likely to be frequently quoted, description of the due diligence plaintiffs must establish when seeking to add a party to an action after the expiry of the presumptive limitation period:
 In my view, it is not to any degree “the standard of perfection” to require counsel to make reasonable, meaningful, endeavors to ascertain the proper owner of the properties involved; but rather it is the reasonable standard of investigation that ought to be expected and provided, in cases such as this.
Master Dash also criticised as unwise the plaintiff’s failure to inspect the site of an accident when ownership may be at issue:
 […] I regard it as unwise to fail to make some investigation of the actual site in cases where ownership is likely to be a key element. However another approach might well be to conduct an examination of the available survey and other information preserved under the province’s Registry System[.]
