Metro Hydrovac Toronto: Book Your Winter 2026-27 Frost-Season Hydrovac Digs, Locates & Disposal Before November
Frost is weeks away. How GTA project managers should line up heated hydrovac days, locates and disposal before the ground freezes this season.
The first hard frost usually reaches the GTA in early to mid November. Once it does, the top layer of ground starts to lock up, and by January a backhoe on a Toronto boulevard can spend more time chipping than digging. If your project has utility exposures, potholes or test pits scheduled between now and April, this is the month to book them.
This post covers what changes for hydrovac work once the ground freezes, how to line up locates and disposal before the rush, and what the published rates look like this winter. For the full scope of what our trucks do in any season, see our hydrovac excavation service.
Why November to April Schedules Slip
Every winter we get the same calls. A site was planning to open-cut a few crossings in December, the excavator hit frost, the crossings were deeper than drawn and the schedule went sideways. Three things cause most of it.
Frost on top. In a normal GTA winter the frost line can push past a metre in exposed ground. Breaking that with a bucket is slow, loud and rough on anything buried just underneath.
Locates expire. Ontario One Call tickets have a life span. When a dig slips three weeks because of weather, the ticket can lapse and the whole thing stops until a new locate is done.
Everyone books at once. The first cold snap sends a wave of calls from contractors who planned to dig with machines and changed their minds. Trucks that were open in October are booked out in December.
How heated hydrovac handles frost
Our trucks heat the water before it reaches the wand. Warm water at 3,000-4,000 PSI cuts frozen soil that stops a bucket, and the 27 inch Hg vacuum lifts it out before it refreezes. The truck does the same job in January that it does in July. It just takes a bit longer per hole.
What to Book This Fall
If you are a project manager or utility supervisor with work running into the cold months, here is the short list we’d suggest locking in before November.
- Book the truck days now. Tell us roughly how many holes, crossings or metres of trench you need, and the window. We’ll hold dates.
- Line up ON1Call locates to match. Request locates so they land a few days before each booked dig, not weeks ahead. That cuts the risk of an expired ticket if weather pushes a day.
- Confirm disposal. Licensed facilities can get backed up in winter, and some close early around the holidays. We confirm the receiving facility when we book.
- Plan traffic control around snow. Snow banks eat lane space. On roads like Finch Ave W or Lakeshore Blvd, cones and signage take longer to set and need more room.
- Ask about standby. On utility relocations, a weekly operated rental with the same operator often works better in winter than separate callouts.
Winter Rates: Same Card, Possibly More Hours
We do not add a winter surcharge. The published CAD rate card for our hydrovac services in Toronto is the same in January as it is in June.
| Truck or service | Rate (CAD) | Minimum |
|---|---|---|
| Standard hydrovac truck + 2-person crew | $280-$350/hr | 4 hours |
| Large tank truck (6,000 gal) + 2-person crew | $350-$450/hr | 4 hours |
| Full 8-hour day | $2,240-$3,600 | Day rate |
| Full-week project rate | $12,000-$22,000 | 5 days |
| Weekend / statutory holiday | $500-$700/hr | 4 hours |
What can change in winter is the number of hours. Frozen ground takes longer to cut than thawed soil, so a job that runs four hours in September might run five or six in January. We estimate that on the quote so the number you receive reflects the season you are digging in.
What Kind of Work Fits Best in Winter
Some jobs are better suited to winter hydrovac than others. These are the ones we see most from December to March:
- Design test pits. Engineers want depths for spring tenders. Getting test pits done in winter keeps the design on track.
- Utility potholing for spring construction. Expose crossings in February so the first excavation crew in April knows exactly what is down there.
- Hydro vault and chamber access. Vault work does not stop for weather, and frozen lids and surrounds are easier to clear with hot water.
- Daylighting before bores. HDD crews often work through winter. Daylighting every crossing first keeps the drill off buried fiber and gas.
- Emergency calls. Water main breaks peak in cold snaps. Our 24/7 emergency hydrovac line covers water mains, sewer backups and insurance claims.
A Note on Safety in Frozen Ground
Winter does not change the rules. Every excavation still follows Ontario Regulation 213/91, ground disturbance near utilities still follows CSA Z247, and every dig still starts with a valid Ontario One Call locate. What changes is the site itself: icy surfaces around the hole, steam reducing visibility, and snow covering paint marks. Our crews re-mark and photograph locates on arrival when snow has covered them, and we bring sand and mats for footing around the excavation.
Book Your Frost-Season Dates
If you have work between November and April, the easiest win is getting it on the calendar before the first cold snap sends everyone to the phone at once. Send the site address, a rough count of holes or metres, and your preferred window, and we’ll hold the dates and confirm the receiving facility.
