What to wear in Toronto in December? With average highs of 32°F and lows of 21°F and 14 wet days including significant snowfall, December in Toronto is full winter. A serious insulated parka, waterproof snow boots, and complete cold-weather accessories are essential from day one of the month.
December in Toronto is a full winter month — average highs of 32°F sit right at freezing, lows dip to 21°F, and the city sees 14 days of precipitation including substantial snowfalls. The Distillery District's Toronto Christmas Market (running through December 23) is one of the city's most beloved events and brings thousands of visitors to the atmospheric cobblestone laneways — beautiful but genuinely cold and icy underfoot. Dressing for December Toronto means returning to the full winter kit used in the depths of January: a parka rated to at least -4°F, thermal base layers, waterproof insulated boots with aggressive grip for the inevitable ice, and full wind protection for the Harbourfront and Nathan Phillips Square's outdoor skating rink. The Eaton Centre, PATH network, and the city's indoor attractions offer excellent shelter — but getting between them requires taking December seriously.

What to Pack for Toronto in December →
December requires the full winter kit: a parka rated to at least -4°F, thermal base layers, waterproof insulated boots with aggressive grip for snow and ice, a hat covering the ears, insulated waterproof gloves, and a scarf or balaclava for wind. The Distillery Christmas Market and Nathan Phillips Square skating rink are spectacular but genuinely cold destinations that punish inadequate clothing. Wind chills can push apparent temperatures well below 10°F by month-end.
December has Toronto's most atmospheric holiday events — the Distillery District Christmas Market is exceptional (runs to December 23), Nathan Phillips Square outdoor skating rink opens, and the city's lights and decorations are at their most elaborate. The cold is significant but manageable with proper gear. Holiday shopping at the Eaton Centre and indoor events at Roy Thomson Hall or Massey Hall provide warm alternatives to outdoor time.
Waterproof insulated boots with aggressive grip soles are mandatory for December. Snow and ice on Toronto's sidewalks and the Distillery District's cobblestones make falls a real risk in inadequate footwear. Boots should be rated to at least -22°F and reach at least ankle height — full mid-calf height is better for navigating snowbanks and slush. No leather-soled boots, heels, or non-waterproof shoes should touch December Toronto pavement.
December averages 32°F (0°C) highs and 21°F (-6°C) lows — the second coldest month after January. With 14 wet days that include significant snowfall and frequent freezing rain, the feel is harsher than the thermometer suggests. Wind chills from Lake Ontario regularly push apparent temperatures below 5°F (-15°C) on cold days. The PATH underground network becomes essential for limiting outdoor exposure.
Pack identically to January and February: a serious parka rated below 0°F, thermal base layers (wool or synthetic), wool sweater mid-layers, waterproof insulated boots rated to -22°F, hat, balaclava or buff, insulated waterproof gloves, and wool socks. A smaller day bag allows you to transition in and out of the PATH network and heated buildings without struggling with a large backpack at every entrance.
