Without knowing what it is you're looking for, other than someone familiar with the Ruger No1 system, it's going to be difficult to point you in any direction.
Several "good" smiths in Canada can do most work on Ruger No1 systems.
There are a few who are experts or at least understand how to fix the issues that go along with No1 rifles.
Ron Smith is a fine smith and does excellent work if you can get him to take on the job. Like many, he's getting long in the tooth but hasn't lost his touch.
Chris Weber of Weber & Markin Gunsmiths in Kelowna is very good, as is Barry from bitsofpieces in Delta.
