Earnings per share [abstract]  
Loss per share Loss per share
The Company has stock options and share awards as potentially-dilutive shares. Diluted net loss per share excludes all potentially-dilutive shares if their effect is anti-dilutive. As a result of net losses incurred, all potentially-dilutive shares have been excluded from the calculation of diluted net loss per share because including them would be anti-dilutive; therefore, basic and diluted number of shares is the same for the years ended March 31, 2023 and 2022. All outstanding potentially dilutive shares could potentially dilute loss per share in the future.
