1. Queen (0111.) 11. Ron Engineering, [1931] 1 S.C.R. 111; 1931 CanLII 17 In response to a call for tenders, Ron Engineering submitted both its bid to do the work for $2 3'48 000, together with the required deposit of $150 000. The tender documents included a term that if a tender was withdrawn the owner could retain the deposit. Once the submitted tenders were opened by the owner, Ron Engineering saw it was the low bidder by a substantial margin. Only then did it discover that they had made a mistake in calculating their total bid price. Ron Engineering informed the owner of the mistake and tried to have the offer changed- The change was refused, the contract was given to another company, and the owner kept Ron Engineering's bid deposit. Ron Engineering sued to get their deposit back, claiming mistake. The owner counterclaimed for costs incurred as a result of having to go with a different bidder. Should the deposit be returned? Will the Court rectify the bid? Does the mistake made by Ron Engineering enable it to get a remedy from the courts
