Can veneers ne placed if the canines are very worn?

Probably: Depends on just how badly worn, they may need root canals and crowns, not just veneers. Ask your dentist.

Cuspid veneers: Yes. If the canine teeth(or cuspid teeth) are very worn , the veneers would wrap over the worn edges.

Yes: Veneers can change shape, color or position of the teeth conservatively

Recommended: These veneers are individually selected to match the rest of your teeth, and shaped according to the golden proportion.

Worn Canines: Are your other teeth also worn? Bruxers tend to grind through porcelain restorations, and sometimes even fracture them. A full mouth evaluation should be made by a dentist experienced in such matters. Seek the opinion of a prosthodontist if you have any concerns.

Worn canines: Placement of veneers is dependent on the overall condition of your teeth, gums and bite, and any oral habits (teeth grinding and/or clenching). Worn canines can be restored, but again, this is dependent on the condition of your teeth and bite. See your dentist for an examination and evaluation.
