Candied violets seem to be impossible to find in Edmonton. My own searches came up with nothing and a post on Chowhound also came back with some good ideas but no source. Instead of buying them online, I figured it would be just as easy to make some of my own - fortunately Court offered her help (and flowers) to do this. I imagine sourcing edible, pesticide-free flowers might have be a little difficult if she didn't have an abundance in her garden.
1 egg white
caster (berry) sugar
These were simple enough to make, though tedious. Using a small paintbrush, paint the flower with the egg/water mixture, then dip it into a bowl of superfine sugar. Move to dry on a baking sheet with wax or parchment paper. See? Simple. It did take several hours though to finish our small bowl of flowers. The end result was worth it though - these really made a plain wedding cake stand out.
