Hey Rob, Im not sure what company handles targets for IPSC BC. I know here in ontario, Doug Lewis does. His phone number is 416-259-1113. For 10 or more classic targets is about $30 and metric targets are about $50. I usually use patches to patch-up my shots to save on targets.
Maybe you can ask Doug if he knows anyone who handles targets for IPSC BC and he can probably lead you the right way. Good Luck.
