Best place for Music Man service in Toronto/north of Toronto area?

I have an old Axis Sport that I want to service. Previous owner made a number of mods and I am failing at getting things to the point that I like them. I’m 3 hours north of Toronto but willing to travel to get the guitar into the right hands for one last try at getting results I like before I give up. It’s a killer player. Looking mainly for electronic/pickup/tone changes, not structural work. Let me know if anyone has any suggestions. Thanks.
