| Know before using | Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels. | An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. | This is federal guidance, not the controlling legislation, an approved label, a product classification, or legal advice. It does not resolve every exemption, fibre test, origin claim, care label, product-safety rule, provincial language duty, or market-specific requirement. Confirm the current Act and Regulations, Quebec and other applicable rules, the actual article and fibre evidence, and the responsible dealer before sale or import. |

| What the source establishes | The maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum. | The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions. | The Competition Bureau guide outlines Canada's Textile Labelling Act and Regulations for prescribed consumer textile articles. It covers fibre percentages and generic names, dealer name and address or CA number, bilingual fibre information, permanent and non-permanent labels, imports, and advertising. The guide also flags additional French-language requirements in Quebec and directs readers to the full Act and Regulations. |
