If you're in Mississauga, I would try giving Angling Specialties a call. Also, I know that there was a place a few years back in Mississauga that serviced reels. They may have also done rod repairs, but I can't remember what the place was called. The guys at Angling Specialties should know for sure.
Not sure about BPS, but I doubt it (unless it's a warranty issue).
what type of guide is it? i have only once had to replace a rod guide and it was a snake guide so i just bent a thick paperclip and wrapped it on with thread and marineglue
