The shrub still green along the back fence in November is often common buckthorn. How to confirm it, which stems you can pull by hand, when a permit applies, and why the berries go in the garbage.
European buckthorn, also called common buckthorn, is usually the last shrub in a yard to drop its leaves, so late October and November is the easiest time to spot it. Confirm it by the short thorn at the tip of the twigs and the finely toothed leaves set mostly in opposite pairs. Pull or lever out stems up to about 5 cm across while the soil is soft, keep the berries out of compost, and bag everything for garbage.

Stakes on the edges, nothing at the curb, a chosen spot for the pile and a dated set of photos. The four jobs to finish before the ground freezes, with the municipal rules behind each one.
Water on the inside of the glass every morning is a humidity reading. Here is the level your type of window can take on a cold GTA night, where the extra moisture comes from, and how to clean a mouldy sill without making it worse.
Fall yard work runs on two clocks: frost decides when the hoses and irrigation must be empty, and the trees decide when the leaves, the last cut and the eavestroughs can be finished. The 2026 pickup dates in your city set the rest.
Vacuum the registers and return grilles, clear the space around the furnace, check the filter and the CO alarms, and learn which smell on the first cold night means dust and which one means leave the house.
Mowing leaves into the grass saves the raking and feeds the soil, but only while you can still see grass through them. Here is where that line sits, how to mow them properly, and when to bag instead.
Find the leak with incense before you buy anything, seal the inside before the outside, and use the October days above 4 °C for the exterior caulking that cannot wait until spring.
Close the inside valve, take the hose off, open the outside tap and let it drain. A frost-free hose bib, a garage tap and an irrigation system each need something different, and Halton charges when a private-side line freezes.
Daffodils, alliums and the small early bulbs belong in the ground by early October; tulips can wait until the soil is close to freezing. Here is the depth for each, and what the Toronto Master Gardeners say keeps squirrels off them.
Window wells before winter need three things: the leaves out, a rim that sits above the ground around it, and a cover that still opens from inside if the window is a bedroom escape route. Here is the order, from the Toronto, Mississauga and federal guidance.
Birds hitting your windows in autumn is a migration problem with a house-level fix: find the one or two panes that cause it, mark the outside of the glass at the right spacing, and move the feeder. Here is what the Toronto and Canadian guidance says works.
Green film on the north-side walkway, moss between the patio stones, black streaks down the roof. Three different problems: a slip hazard, a cosmetic stain, and growth that can lift shingles. How to tell them apart and what each needs.
A vegetable bed in late September holds three decisions: which plants can go in the composter, which ones must leave the property, and whether garlic goes in this week. Toronto's growing guide and Ontario's vegetable specialists settle all three.
The garage fills up with fuel, batteries, paint and lawn products every summer. Ontario's Fire Code puts a number on the fuel, and the labels and fire services settle most of the rest. Here is what may stay out there until spring.
Autumn cleanup puts hands, rakes and string trimmers into exactly the fence lines and shrub borders where poison ivy grows. The leaves are dropping, the stems are not harmless, and the ten minutes spent finding it first decide how the rest of the job goes.
Nothing in Halton, Peel or Toronto stops you from pressure washing your own driveway. All of it regulates where the water goes afterwards, and the grate at the bottom of the slope is the part that turns a Saturday job into an offence.
Earwigs, sowbugs and millipedes in a basement are a moisture report from the outside of the house. Which one you find tells you where to look, and most of the fix is mulch, leaf litter, downspouts and grading rather than a spray.
Lady beetles, cluster flies and stink bugs on a sunny wall in September are looking for a place to spend the winter, and the gap they use is usually around a window. What to seal, what to leave alone, and why a spray is the wrong tool for two of the three.
Three of the five municipalities we work in still require a permit to take down a dead ash, and the wood cannot leave the federally regulated area. Here is what each one asks for and where the trunk is actually allowed to go.
The plow ridge at the end of your driveway is handled five different ways inside 30 km. In three municipalities the answer for this winter is decided by a form in October.
Three Ontario sources give three cutoffs for autumn seeding, and by the middle of September two of them have closed. What each one measures, what the 30-year temperature record shows, and what seed put down this week can do.
The last outside window clean of the year is decided by three things: when the leaves are down, when the gutters are done, and how many days are left that stay above freezing. Here is how to pick the date in the GTA.
Mid-September is when most of the yard gets cut back. The oak is the one tree that does not, and the reason is a fungus that has been confirmed in Ontario since 2023. Here is what every level of government actually says about the date.
Spongy moth egg masses go up around mid-August and sit on fences, eavestroughs, furniture and bark all winter. Autumn is the window to take them off — and the part worth getting right is telling them apart from the native masses that belong there.
