According to the Canadian building code:
9.23.5.3. wall studs
(1) wall studs shall not be notched, drilled or otherwise damaged so that the undamaged portion of the stud is less than two-thirds the depth of the stud if the stud is loadbearing or 40 mm if the stud is non-loadbearing, unless the weakened studs are suitably reinforced.
How do you run a 1.5" ABS pipe through a single 2x6 stud then? One third of a 2x6 is slightly less than 1 7/8" which isn't big enough to run the ABS pipe. I see that Simpson makes stud shoes, but those don't seem to be available anywhere and even then, seem to require engineering sign off rather than being a sure fix.
Other places say that you can double up the stud as long as you aren't drilling more than two consecutive pairs, but that seems to be in the US vs Canada.
