Activities is the correct word.Kyle Burrows said:Read the CATO - http://cadets.ca/_docs/cato-oaic/1103_b.pdf
Looks like exactly what is going on here. Nobody is trying to press gang cadets, stimulating their interest is right up the alley of the CCM. Personally, I find activities to be the perfect word.
You originally suggested "foster an interest in the different elements of the CF." Which admittedly is found incorrectly in some materials.
The word element is not anywhere in the CATO 11-03 or in the aim as stated in QR&O Cadets. There is a difference and the message is different with regard to the outcome of the cadet organization.
