• Canon has been actively releasing new mirrorless cameras like the EOS R6 Mark III, a full‑frame interchangeable‑lens model launched in late 2025 with weather‑resistant construction — but this is a general photography camera, not a dedicated weather camera category product.

• The company has also introduced various imaging and video‑focused products in 2025, including compact and cinema‑oriented cameras, but none have been described by Canon or verified news outlets as a first new weather‑camera model in 20 years.

If you meant a camera designed for harsh outdoor / all‑weather use (e.g., rugged weather‑sealed units), Canon’s professional mirrorless and DSLR bodies have long included weather‑resistant sealing as a feature — not a totally new distinct weather‑camera category.

Many of Canon’s recent bodies (like the R5, R6, and R1 series) include robust weather resistance, but these aren’t the first new weather camera in decades — they’re evolutionary updates to existing lines.
