Pinnacle Packing Inc. manufactures and supplies corrugated packaging boxes — RSC shippers, die-cut cartons, heavy duty double wall, sheets and Gaylord bulk containers — to 3PLs, manufacturers, movers, warehouses and ecommerce sellers across Toronto, Mississauga and the Greater Toronto Area.
Strong. Reliable. Cost-Effective Packaging.
The RSC is the default corrugated cardboard box for shipping: one piece of board, flaps that meet in the middle, and the lowest cost per carton of any style we make. If you need a corrugated box for shipping ecommerce orders, stock replenishment or moving jobs, this is almost always where the quote starts. Available in single or double wall depending on what the carton has to carry, and printed or plain.
Precision-Crafted Packaging for a Perfect Fit
Our Die-Cut Corrugated Boxes are custom-designed packaging solutions engineered to match your exact product dimensions and structural requirements. Unlike standard RSC boxes, die-cut boxes are manufactured using specialized cutting dies to create unique shapes, folds, inserts, and locking mechanisms.
A die-cut corrugated packaging box holds the product snugly, which removes void fill, protects better in transit and presents properly when the customer opens it — the reason retail and subscription brands specify them over stock sizes.
Maximum Strength for Demanding Shipping & Industrial Use
Our Heavy Duty Corrugated Boxes are engineered for superior durability, high load capacity, and long-distance transport. Designed to handle heavy, bulky, or fragile items, these boxes provide enhanced protection during storage, handling, and shipping across Canada.
Built using high-strength double wall or reinforced corrugated board, heavy duty boxes are ideal for industrial, commercial, and export packaging applications.
Durable, Flexible & Customizable Packaging Material
Our Corrugated Sheets are high-quality, multi-layered protective sheets designed for packaging, layering, cushioning, and manufacturing applications. Manufactured using strong kraft linerboard and premium fluting, these sheets provide excellent strength, flexibility, and shock absorption.
Corrugated sheets are widely used across industries in Canada for custom box production, product protection, pallet layering, and industrial packaging.
Heavy-Duty Bulk Packaging for Industrial & Warehouse Use
Our Gaylord Boxes are large, heavy-duty corrugated bulk containers designed for high-volume storage, shipping, and material handling. Built for strength and durability, these boxes are ideal for transporting bulk products, recyclable materials, agricultural goods, and industrial components across Canada.
Gaylord boxes are commonly used on pallets and are engineered to handle substantial weight while maintaining structural integrity during stacking and transit.

Corrugated box selection by application. Board strength is confirmed per order against your product weight and stacking requirements. Every corrugated packaging box is quoted on board grade, flute type and exact internal dimensions — we do not publish fixed specifications for every size because they are matched to your product.

Why Pinnacle
Most corrugated box manufacturers in Ontario, Canada sell you board and stop there. We quote the corrugated packaging box alongside the tape that seals it and the film that holds the pallet together, which is what a warehouse actually orders in a week.
We work from 2895 Hazelton Place in Mississauga, so GTA orders run on local lead times rather than out-of-province schedules — the practical reason to use corrugated box manufacturers in the GTA rather than a distant mill. Board strength, wall type and internal dimensions are matched to the product being shipped, not pulled from a catalogue, and repeat orders are held to the same specification.
As a corrugated boxes supplier we handle both ends of the scale — a single-pallet first order and a standing weekly supply schedule — with straightforward quoting and Ontario-wide availability. Need to secure pallets too? Our stretch wrap and packing tapes complete the shipping setup, and industry-specific packaging guidance is available if you want a full review of your line.
Tell us your box size, quantity and wall strength — we'll come back with pricing and stock availability. Ordering for ecommerce? Ask about repeat-order pricing on RSC shipping boxes.

Why Businesses Choose Us
Board grade, wall type and internal dimensions are specified against your product weight and stack height — not picked off a catalogue page.
Manufactured and stocked in Mississauga, so a GTA reorder runs on local lead times instead of an out-of-province schedule.
Send your specification and we'll come back with pricing and stock availability. The more detail you include, the faster we can quote accurately.
"Cardboard" is often used loosely, but true corrugated board has a fluted middle layer between two liner sheets, giving it far more cushioning and stacking strength than single-ply cardboard/chipboard — which is why it's the standard for shipping boxes.

We manufacture and supply. Orders are produced and stocked locally and shipped from Mississauga, which is what separates us from importers reselling containers of stock sizes. Businesses comparing corrugated box manufacturers in Toronto usually care about two things — lead time and whether the board spec stays identical on the reorder. Both are handled here.
A corrugated packaging box has a fluted layer glued between two liners, and those flutes carry the stacking load and absorb impact. Plain cardboard — paperboard — is a single solid layer with no flutes, fine for a retail carton but not for freight. Our guide explains the difference in full.
