14. Loss per share

Basic and diluted loss per share are calculated using the following numerators and denominators:

Numerator		2022			2021		2020
Net loss attributable to common shareholders and used in computation of basic and diluted loss per share	$	(2,287,095	)	$	(1,012,978	)	(1,245,393	)

Denominator
Weighted average number of common shares for computation of basic and diluted loss per share		451,177,796			422,613,046		377,380,476

For the years ended October 31, 2022, 2021 and 2020, all stock options and conversion features were anti-dilutive and, therefore, are excluded from the calculation of diluted loss per share.
