Finally a reply from Strathcona
Three days later:
"Regarding fractional shares, Pipestone’s management information circular dated August 25, 2023 states “in calculating such fractional interests, all Pipestone Shares registered in the name of or beneficially held by such holder thereof or their nominee shall be aggregated.” Beneficial owners are aggregated through CDS (Clearing Depositary Services) and therefore paid as one holder. Any further rounding is between CDS and the brokers, and ultimately up to the brokers on how they allocate the shares to their underlying clients. We encourage you to contact your broker for any discrepancies resulting from their allocations."
Frankly that sounds like BS to me. Pass the buck when you do not know how to correct a problem.
