Well since the gym is along the way to the armoury, I thought it would be advantageous to just not carry so many different clothing articles around. I would be already in my uniform, change to my civilian gym clothes and work out, then change back into my uniform and head toward the armoury.
I understand your point as well.
I do that exact thing every morning. You're not carrying anything more if you head to the gym in your gym outfit, then change.
From the dress regs (http://www.cmp-cpm.forces.gc.ca/dhh-dhp/pub/ins-265/index-eng.asp):
"19. “On duty”. As a general rule, for purposes of dress and appearance, a member is considered to be on duty:
a. when actively engaged in operations, training or administrative duties, either in accordance with specific orders or in accordance with established military routine or practice;
b. when attending a course or administrative function, either in accordance with specific orders or established routine or practice;
c. when participating in or attending any sport, recreational, social or other activity where military authorities require her/him to be there; or
d. when he/she is at a specific place, or doing a specific act, because of a military order.
37.Reserve Force (Class C excluded). Members of the Reserve Force shall not wear a uniform except when:
a.on duty, or proceeding to or from their place of duty;
b.attending a military function or ceremony at which the wearing of uniform is appropriate.
38.Proceeding to or from Place of Duty. Commanding Officers may order members of the Regular and Reserve Force to wear uniforms when proceeding to and from their place of duty where it is considered appropriate to do so in the circumstances, having regard to the custom and practice of the CAF."
I hope that helps with your decision.
