Very slender body, two translucent wings, each
with a white spot. Stands on leaves for hours.
Never seen more than one in the garden, at a time.

I believe that it's a dragonfly (rests with wings outstretched),
damselfly (rests with wings folded backwards and horizontal) or
demoiselle fly (rests with wings folded backwards and vertical). (Lestes
damselflies rest with the wings in a V-shape.) But all these have 4
wings.

A very slender body suggests a damselfly. If the photograph shows one
resting, then a demoiselle fly.

I assume that in Canada you have a different set of species to here.
Ontario alone has 130 species, so you have quite a few to check out.
