An older Saskatoon home may have detectors that predate current City of Saskatoon placement requirements, so your agent or inspector should check not just whether detectors exist but whether they are positioned correctly and within their manufacturer's service life, since an expired unit can fail exactly when needed.
If the home has a secondary suite, the City of Saskatoon's permit conditions for that suite typically include its own detector requirements separate from the main dwelling, so a legal suite needs its own check, not just the primary residence's.
Raising any gap in writing before you remove your inspection condition gives you a clear path to have it fixed before possession rather than discovering it after you already own the house.
