Here are the best job boards and places to look specifically for manufacturing jobs in Canada, with a short note on why each is useful and a quick tip for getting better results.

Top choices

• Job Bank (Government of Canada) — Official national job board with wide coverage of manufacturing roles across provinces and good labour-market data (wages, outlook). Great for regulated/union and public-sector manufacturing listings. (en.wikipedia.org)
  Tip: Use the advanced filters and labour-market reports to target occupations and regions with the highest demand.

• Indeed (Canada) — Largest aggregator in Canada (pulls listings from many company sites and boards), high volume of manufacturing postings and easy-to-use alerts. Good for entry-level and shift-worker roles as well as engineering/ops postings. (Betterteam.com)
  Tip: Set job alerts with specific titles (e.g., “CNC operator”, “maintenance millwright”) and filter by salary/location.

• LinkedIn Jobs — Strong for professional/engineering/management roles in manufacturing, and for discovering hiring managers and company pages. Useful for networking and passive opportunities. (new.747canada.com)
  Tip: Follow target companies and join relevant Canadian manufacturing groups to see openings earlier.

• Eluta — Canadian job search engine with many employer-direct manufacturing listings (often includes postings you won’t find elsewhere). Good for searching by city and employer. (Eluta.ca)
  Tip: Use employer-specific searches (e.g., “Mondelez manufacturing jobs”) to find factory/plant openings.

Industry‑focused / specialized boards

• Manufacturing Job Site (manufacturingjobsite.ca) — Canada-specific manufacturing/industrial board; targeted audience for operations, production, engineering and skilled trades. Useful for highly industry-specific roles. (manufacturingjobsite.ca)
  Tip: Create job alerts for niche keywords (e.g., “lean manufacturing”, “MES”, “plant manager”).

• ManufacturingJobs.com & ManufacturingJobs.ca-style aggregators — North American manufacturing boards that list Canadian openings; useful for reaching candidates with specific shop-floor or engineering skills. (Betterteam.com)
  Tip: If you’re applying, search by company and use location filters — some postings are cross-listed from U.S. operations.

• Sector-specific sites — e.g., CareersInFood (food processing), LondonMFGJobs and local/regional sites — useful when you want highly targeted roles in a sub-sector. (Betterteam.com)

General aggregator/marketplace options (also worth checking)

• ZipRecruiter, Monster, Glassdoor — broad reach and useful for mid-senior roles or when you want many applications quickly. (Betterteam.com)

How to search smart (quick checklist)

• Use precise titles and keywords (CNC operator, maintenance millwright, production supervisor, process engineer).
• Set email alerts on 2–3 boards (e.g., Job Bank + Indeed + Eluta or Manufacturing Job Site).
• Search company career pages for large manufacturers (often post plant roles there first).
• Use LinkedIn to find hiring managers and get referrals — especially for salaried/engineering roles.
• If you’re a tradesperson, check provincial apprenticeship portals and union/job-placement centres in your region.

If you want, I can:

• Narrow this list to a province or city (Ontario, Quebec, Alberta, etc.) and highlight local boards and employers; or
• Provide sample search filters/keywords for a given role (e.g., CNC operator, maintenance electrician, production supervisor).
