Alberta — Highway 2 (QEII) & Highway 16 (Yellowhead)

Alberta's main corridors: no closures overnight

Overnight reports for the Calgary–Edmonton QEII (Highway 2) and the Yellowhead (Highway 16) were uneventful: no closures on either corridor, surfaces mostly dry with ice in places, and the coldest corridor reading -4°C near Red Deer in the 2:49 a.m. MDT update. Dry pavement plus sub-zero air is the classic setup for a thin, invisible layer on bridge decks and shaded ramps — the hazard this morning is the ice you can't see, not a storm you can.

Alberta — weather

Environment Canada: no alerts in effect for Alberta

Environment Canada carried no warnings, watches, or special weather statements for southeastern Alberta in its Monday 5 a.m. forecast, and the settled pattern ran through the night: sub-zero starts across the region — Monday night's low of -1°C in the southeast was the only below-zero overnight reading there — under a mix of sun and cloud. This is freeze-patrol weather, not storm weather: the stretch of the season where what freezes in a parked cab matters more than what is falling.

British Columbia — Highway 5 (Coquihalla)

Coquihalla stayed open — three work zones in effect

Highway 5 between Hope and Kamloops was open to through traffic all night, and DriveBC's feed showed it running on time in the small hours — Merritt to Kamloops at 1h 53m against a 1h 51m typical at the 1 a.m. PDT check. Three work zones are in effect along the corridor through Oct 31, so the pass being clear does not mean the drive is: expect sudden stops and lane shifts.

British Columbia — designated routes

BC chain season is already on

Not an incident — a standing rule now in force, and the one that catches drivers every October. Since Oct 1, designated BC highways require winter tires (M+S or the mountain-snowflake symbol, minimum 3.5 mm tread) on passenger vehicles, and commercial vehicles must carry chains — in effect until Mar 31 or Apr 30 depending on the route. Signs mark where each requirement starts, and non-compliant vehicles can be turned around.

Highway 1 overnight lane closures: North Vancouver & Abbotsford

DriveBC's event list has Highway 1 in North Vancouver (Exit 21 Mountain Hwy to Exit 19 William Ave) under lane closures in both directions overnight this week — Mon Oct 19 to Wed Oct 21, 10 p.m. to 5 a.m. PDT — with traffic control in place. In Abbotsford, the Whatcom Road westbound on- and off-ramps are closed overnight (7 p.m. to 6 a.m.) through Oct 22, and the Highway 1 entrance ramp at Exit 170 in Hope closed Sunday night into Monday morning for paving.

Ontario — Highway 401 corridor

Southern Ontario: fog patches, patchy frost this morning

Environment Canada's Tuesday outlook for the GTA and southern Ontario calls for early fog patches — Hamilton and the Niagara area especially — and patchy frost, after overnight lows of 2 to 3°C. The day itself turns warmer than usual, with highs near 16°C in Mississauga, so the hazard window is the morning roll-out: frosted glass, slick bridge decks, and fog in the low stretches of the 401 and QEW.

Bottom line for drivers

Nothing major closed overnight. This morning's risks are the quiet ones — frost on glass and bridge decks, patchy ice on Alberta's corridors, and work-zone lanes on the Coquihalla and Highway 1. BC's chain season is already in force. Check 511 before you roll.
