Check pawn shops. It's a long shot, but you might find something interesting and vintage there.
What size does she wear?
Don't know how easy it is to get things from the US to Canada, but here's a pretty little wedding band for budget. Unfortunately, it's an auction but you might get the seller to do a BIN: http://www.ebay.com/itm/Antique-14k-Gold-Two-Tone-Diamond-Band-Ring-/221211289834?pt=LH_DefaultDomain_0&hash=item33813868ea
This is more engagement-ring-y: http://www.ebay.com/itm/Antique-Diamond-Heart-Engagement-Ring-Two-Tone-14K-Gold-/390572811301?pt=Diamond_Solitaire_Rings&hash=item5aeff42425
This seller has many vintage items at budget prices.

She's a size 7
I might try pawn shops as a last resort. The pawn shops around here are pretty sketchy!
