Though I am not familiar all of the luthiers practicing in the Victoria area, I can recommend:
Conor Searl in Duncan- https://www.searlguitars.ca/get-in-touch 250-710-0747
Darcy Clark, Doc’s Guitar Repair, in Courtenay, 250-703-9713
For bowed instruments, violin, etc., – Olivia Pelling, olivia@finestrings.ca 778-268-3973 in Nanaimo
For brass/woodwind instruments – Claudio Fantinato, Highnote Musical services in Qualicum Beach, 250-954-8092
For Piano tuning and electronic keyboard repair – Steve Ruskin, noteworthy@shaw.ca, 604-857-0554 in Courtenay
Sadly the professional instrument repair resource has been reduced by 2 fine craftsman in recent years with the passing of Dave Cahill of Old Town Strings in Victoria, and the retirement of Richard Leighton of Arbutus music in Nanaimo.
