Law360 Canada ( June 10, 2025, 2:41 PM EDT) -- Appeal by appellant RMC Construction Materials Ltd. (RMC) concerning the interpretation of an agreement between it and RBee Aggregate Consulting Ltd. (RBee). RMC, which supplied ready-mix concrete and related services, entered into a supplier agreement with RBee for the delivery of washed and crushed aggregate gravel for a BC Hydro project. RBee was to deliver the aggregate to a stockpile at the worksite. Between May 2018 and September 2021, RBee issued approximately 35 invoices, which RMC paid. However, from September to December 2021, RMC refused to pay three invoices totalling $4,485,480, claiming that RBee delivered less aggregate than invoiced and alleging overbilling throughout the arrangement. The respondent FTI Consulting Canada Inc. (FTI) was appointed as the receiver for RBee’s property and sought payment from RMC for the outstanding invoices. RMC argued that the amount was not due because RBee overbilled and claimed a set-off of over $7 million. The chambers justice found that the invoices were due and payable according to the supplier agreement and that the appellant had not established its set-off claim on a balance of probabilities. The justice concluded that the agreement required RMC to verify the volume of aggregate delivered within 60 days, failing which the appellant could not contest the volume reported by RBee. RMC appealed, arguing that the chambers justice erred in interpreting the agreement and in excluding evidence....
