Plastic sheds and wooden sheds are both widely available in Ontario and both solve the basic problem of outdoor storage. The right choice depends on what you need the shed to do, how long you need it to last, and what you want it to look like sitting in your backyard.
Here is how they actually compare.
Plastic sheds are made from moulded polyethylene or PVC panels that snap or bolt together. They are sold flat-packed, assembled on site, and designed to be maintenance-free. They are the most affordable shed option and the easiest to put together.
Wooden sheds are framed structures built from lumber with wood, cedar, pine, or steel siding. They require more investment upfront but are structurally stronger, more customisable, and better suited to Ontario's climate in most situations.

This is where the comparison gets important for Ontario buyers specifically.
Plastic sheds do not rot and do not rust. Those are real advantages. What they do poorly in Ontario is handle the structural demands of winter. Snow load on a plastic shed roof can cause panels to flex, crack, or collapse under significant accumulation. Freeze-thaw cycling loosens the connections between plastic panels over time. And plastic becomes brittle in sustained cold, making damage from impact more likely in winter.
A wooden shed built with quality framing lumber and appropriate roofing handles Ontario snow loads, freeze-thaw cycling, and temperature swings far better. The structural integrity comes from the framing, not the panels, which means a wooden shed holds its shape through years of Ontario winters in a way that a plastic panel shed does not.
A plastic shed looks like a plastic shed. The moulded form, the limited colour options, and the surface texture are recognisable from across the yard. You cannot paint it, re-side it, or meaningfully change how it looks once it is assembled.
A wooden shed can be finished in any colour, stained in any tone, and sided in a range of materials. It can be designed to complement your home rather than sit in contrast to it. If you want to change the look later, you re-stain or re-side -- you do not replace the whole structure.
For homeowners who care about how their backyard looks, this is not a minor point. A shed that looks considered and well-made adds to the property. One that looks like a plastic box in the corner does not.
The assumption that plastic sheds require no maintenance and wood sheds require a lot is outdated. The reality depends entirely on what siding is on the wooden shed. BES offers three tiers of maintenance depending on which siding combination you choose.
BES's corrugated steel siding, supplied by Agway Metals, carries a 40-year manufacturer's warranty against fading and chalking. No painting, no staining, no upkeep ever. The pre-painted finish is baked on and the 7/8 inch corrugated profile gives it natural resistance to everyday bumps and impacts. A shed clad entirely in corrugated steel requires zero maintenance to the exterior -- it will look the same decades from now as it does the day it is installed.
BES also offers West Ridge luxury vinyl panel by Mitten Building Products. This is not the commodity vinyl that makes a shed look cheap -- it is an 8 inch wide flat single plank panel with a foam backing and a lifetime warranty that reads as modern shiplap from across the yard. Completely maintenance free. Zero painting, zero staining, zero upkeep. For buyers who want a clean contemporary look without ever picking up a brush, West Ridge delivers that without the plastic shed trade-offs on durability and structure.
BES's most popular combination is corrugated steel on the back and sides with a stained wood front face. The steel sides are completely maintenance free. The wood front face needs a light re-stain every few years -- a straightforward job that most homeowners handle themselves in an afternoon. That is all. The shed will last a very long time with that minimal upkeep cycle.
A shed clad entirely in pine or cedar siding needs periodic re-staining across all faces to stay protected and looking good. BES hand-stains all siding before installation, which gives the finish a head start. But all-wood siding requires the most ongoing attention of the three options.
The key point is that the maintenance argument that favours plastic sheds does not apply to BES builds using steel or West Ridge siding. A BES shed in corrugated steel or West Ridge requires the same zero maintenance as a plastic shed -- and significantly outperforms it on durability, structure, appearance, and longevity.
A plastic shed is a storage box. It does that job adequately for seasonal items and basic lawn equipment.
A wooden shed can be a storage shed, a workshop, a pool equipment shed, a potting shed, or the base for a finished studio space. You can add shelving, hooks, and built-in storage. You can insulate it and fit it out for year-round use. You can add a proper door with a quality lock. None of that is realistic with a plastic shed.
If there is any chance you will want to use the shed for more than basic storage, a wooden shed is the only option that keeps those possibilities open.
A plastic shed costs less upfront -- typically $500 to $2,000 depending on size. A quality wooden shed starts higher.
The comparison changes over ten or fifteen years. A plastic shed that needs replacing because panels have cracked, the roof has failed, or connections have loosened costs more in the long run than a well-built wooden shed that lasts twenty or more years. Replacement also means disposal, reassembly, and the disruption of starting over.
The total cost of ownership over a decade strongly favours a quality wooden shed for anyone who plans to stay in their property long term.
For basic seasonal storage on a tight budget where longevity and appearance are not priorities, a plastic shed does the job.
For anyone who wants a shed that lasts, looks good, and leaves options open for future use -- and does not want to maintain it -- a BES shed in corrugated steel or West Ridge siding matches the maintenance argument of a plastic shed and beats it on every other measure.
For buyers who want the warmth of natural wood and do not mind a light re-stain every few years, the steel and wood combination is the sweet spot: low maintenance, genuine character, and a structure built to outlast any plastic shed on the market.
