Quick answer: Shrinkwrap is cheaper and weatherproof but condenses moisture inside if vented poorly. Indoor storage is dry, climate-stable, and gentler on upholstery and gel coat, but costs more. For long-term value retention, indoor wins. Indoor and shrinkwrap pricing at mercuryrepower.ca.
Decision guide
Shrinkwrap outdoors, or pay for indoor storage?
The right answer depends on your boat type, where you live, and how much you trust your tarp. Here's how we actually advise customers each fall.
Shrinkwrap outside
- ✓Aluminum or fiberglass hull in good condition
- ✓You have a paved driveway, lakeside lot, or low-cost outdoor space
- ✓You don't mind a small risk of wind/snow damage if the wrap fails
- ✓Your boat is under $40K replacement value
- ✓You winterize properly and the boat isn't sitting in salty conditions
Typically $300 to $700 in Ontario for shrinkwrap + outdoor spot. Cheapest option that still seals out snow, ice, and most rodents.
Indoor storage
- ✓High-value boat ($40K+) or rare/collectible hull
- ✓Wooden interior, real leather seats, or sensitive electronics
- ✓You want the boat ready to launch in April without a full prep cycle
- ✓You live in a high-wind zone, near salt-treated roads, or under heavy trees
- ✓You want to keep the gel coat looking new for resale
$900 to $2,200 in Ontario depending on heated vs unheated and length. Worth it on high-value or low-tolerance boats.
When in doubt:Most Rice Lake customers shrinkwrap outside. If you're 50/50 on it, the cheap option is shrinkwrap; the safe option is indoor. We do both, book either at /service.
Planning a spring repower instead of another season on the old motor? See Mercury Repower Cost: Ontario 2026 (CAD), the Ontario Mercury Outboard Price Guide, and the Mercury Controls & Rigging Guide (Ontario). For maintenance on the existing motor, Mercury Maintenance Intervals (20/100/300-Hour Rule) covers what should be done before winter.
Every fall we have the same conversation about thirty times. "Is shrinkwrap enough? Should I pay for indoor? Is heated worth the extra money?"
The honest answer: for 90% of Ontario boaters, professionally shrinkwrapped + properly winterized + outside is the right call. The other 10% have a specific reason, wood boat, classic, very high value, or a need to access the boat through the winter, that justifies indoor.
Here's the math, the protection comparison, and the decision framework. Plus the cost of getting it wrong, which is the part most pricing pages skip.
Why Winterization Is Non-Negotiable in Ontario
Let's get this out of the way first: storage method doesn't replace winterization.
Ontario gets to -20°C and colder regularly between January and February. Even indoor unheated storage drops below freezing during cold snaps. The only storage tier that lets you skip winterization is heated indoor, where the building stays above 5°C all winter, and even then, fuel stabilization is still recommended.
What happens if you skip winterization (regardless of storage method):
| Failure |
Cost to Fix |
| Cracked engine block (water freezes inside cooling passages) |
$5,000 - $10,000+ engine replacement |
| Cracked lower unit / sterndrive (water freezes in the gearcase) |
$1,500 - $4,500 |
| Corroded cylinder walls (no fogging oil = surface rust over winter) |
Loss of compression in spring, rebuild work |
| Gummed fuel system (untreated ethanol breaks down, clogs injectors) |
$200 - $800 |
| Dead battery (left uncharged in freezing temps) |
$200 - $500 replacement |
Your storage choice affects what else protects the boat. UV, snow, wind, pests. It doesn't change the freeze-protection requirement.
Shrinkwrap Storage. Ontario's Default, and Why
Shrinkwrap is 7-12 mil polyethylene film, heat-shrunk tight over a support frame, with venting installed to prevent condensation. It's designed to handle a season, single use, recyclable in spring.
A professional shrinkwrap job includes:
- Boat cleaned and dried
- Support poles erected to create a peaked roof (so snow doesn't pool)
- Film draped, heat-shrunk to fit
- 2-4 vents installed (without these, you'll have mold by April)
- Strapping for wind and snow load
- Access door cut for spring un-wrapping
Pros:
- Excellent water/snow barrier, better than canvas, way better than tarps
- UV protection, gelcoat doesn't fade
- Custom-fit to any shape, pontoons, fishing boats, cruisers all wrap fine
- Cost-effective, cheapest professional storage tier
- Can be done at HBW or at your house with mobile shrinkwrap service
- Recyclable, programs exist for spring removal
Cons:
- Single-season, gets removed and recycled in spring, paid every year
- Vents required or you'll have mold (this is why DIY shrinkwrap with no vents is worse than no cover)
- Snow load failure if the support frame is weak or undersized
- No temperature regulation, same temperature as outside
HBW pricing 2025-2026: $33/ft for trailer boats up to 21 ft, $35/ft for larger. That's $693 for a 21-ft fishing boat or $770 for a 22-ft pontoon, including the wrap, the frame, the vents, and the strapping.
Other Ontario dealers: outdoor shrinkwrap storage runs $30-$37/ft across the province; some marinas charge $58/ft for outdoor with shrinkwrap (Muskoka pricing).
Indoor Unheated Storage. When It's Worth the Bump
Indoor unheated is the next tier up. Building keeps the boat out of the elements but doesn't heat. Important: even indoor unheated storage drops below freezing in Ontario January, so you still need full winterization.
Pros vs. shrinkwrap:
- No UV exposure (gelcoat protection on aging hulls is real)
- No snow load, period
- No wind damage to cover
- Better pest control (sealed building)
- Possible insurance savings
- You can access the boat through winter for maintenance, electronics work, etc.
Cons:
- Costs more, typically $40-$60/ft including basic shrinkwrap or cover
- Limited availability, most Ontario indoor capacity books out by September
- Drop-off windows, you can't just show up; storage facilities want appointments
- Condensation without good air circulation in the building
Ontario pricing for indoor unheated:
- $37/ft (other regional marinas, 9-month contract)
- $40-$60/ft including shrinkwrap (urban GTA marinas Belleville and others)
- $55/ft (cottage-country marinas)
For most aluminum fishing boats, pontoons, and modern fibreglass runabouts, the protection delta over outdoor shrinkwrap doesn't justify the cost. For older fibreglass, dark-coloured gelcoat, or a hull where you want to slow oxidation, it's worth considering.

Indoor Heated Storage. The Premium Tier
Heated indoor keeps the building above 5°C (40°F) all winter. The differentiator isn't UV or snow, it's that the boat doesn't experience freezing temperatures at all.
Pros vs. unheated:
- No freeze risk, you can technically skip winterization, though we still recommend fuel stabilization and a basic service
- Protects electronics, vinyl, upholstery from cold-cycling damage
- Best for high-value boats, classic boats, wooden boats
- Can use the boat for off-season maintenance without warming it up
Cons:
- Most expensive option: $60-$90/ft, sometimes more
- Very limited availability in Ontario, heated boat storage is a niche service
- Energy costs are real and increasing
- Some still require partial winterization (fuel, oil) regardless
When it's worth it:
- Wood boats (period correct, restored, classic)
- Boats over $100K where the marginal cost is small relative to the asset
- Boats with sensitive electronics that you'd rather not see thermal-cycle through winter
- Boats you'll genuinely use in the off-season for repairs, photo work, or polish
When it's not:
- Standard aluminum fishing boats
- Most pontoons under $50K
- Anything where the storage premium would buy a meaningful upgrade elsewhere

For a typical 21-ft Ontario fishing boat or pontoon, outdoor shrinkwrap saves $500-$1,200 over indoor, money that's better spent on winterization done right, a quality cover frame, and an early-spring service.
What "Done Right" Looks Like at HBW
Our standard winter storage package includes:
- Full shrinkwrap with support frame, 2-4 vents, and weather strapping
- Mercury-trained winterization on the engine: fuel stabilization, fogging, gearcase drain and refill
- Cooling system drain (freeze protection)
- Steering and throttle cable lubrication
- Anode inspection
- Battery removed and brought indoors on a trickle charger through winter
- Optional: spring commissioning add-on (we pull it off, prep it, water-test, deliver to your slip)
Pricing: $33-$35/ft shrinkwrap + winterization fees ($300-$700 depending on engine size). All-in for a 21-ft fishing boat with a 90 HP 4-stroke is roughly $1,000-$1,200. For a 22-ft pontoon with a 115 ELPT CT, $1,200-$1,400.
We do 311+ storage contracts a year. That's a meaningful chunk of our fall and spring shop time. The system is dialled in, you drop it off, you pick it up, the boat works.
Booking Lead Time Matters
The mistake we see every year: customers calling in early November to book winter storage. By that point we're at capacity and so is every other dealer in Ontario.
Best practice:
- September: Booking opens. Best pricing, full slate of dates available.
- Early October: Still good. Most popular drop-off windows starting to fill.
- Late October: Squeeze territory. Fewer date options.
- November: "Sorry, we're full" most years.
If you're new to HBW, calling in late August / early September means you get into our system, you get a confirmed date, and you know the price ahead of time.

If you're shopping for storage locations beyond shrinkwrap details, our Kawartha Lakes storage overview covers options across Rice Lake and the broader region.
What we see at HBW
We've been shrinkwrapping boats on the south shore of Rice Lake for decades. Most years we wrap 300-400 boats between October and mid-November. The customers who pay the indoor-storage premium at other facilities are usually offshore fiberglass owners ($75K+ boats) or commercial guides. For the typical aluminum fishing rig or 19-foot pontoon, outdoor shrinkwrap is the smart spend.
What separates a good shrinkwrap job from a bad one: tying the tarp to a frame, not just to the gunwales. Snow load splits ungo unframed wraps by January every year. We frame every wrap.
