Rules in the bylaw's general sections (parking, fences, suites, home businesses) also apply, and a lot can have site-specific rules. The City says its online bylaw copies are meant to be up to date but are not legal versions and may not include the most recent amendments. The consolidation date is not stated in the PDF. Zones are grouped in shared tables per category (A, RS/RTh/RRh/RA, NC/CC/DC/SSC/RC, M, P), so lines for those zones give the whole category section. There is no CD37 in the bylaw. Zone pages are taken from the bylaw text by a research agent and have not yet been reviewed by a person: confirm with the bylaw before you rely on them. How answers are checked.
