Northern Lights Tonight in Montreal, Quebec

Montreal needs a real storm before the aurora boréale shows from the city. At 4.9, you will see it only a handful of nights each year, and then mostly as a faint glow low over the north shore. The island is large and bright, and the light dome spreads well past the river on every side.

What helps is that north of the island the land opens up. Laval, the Laurentians and the Lanaudière farmland lie across the Rivière des Prairies, so a drive north puts you in dark country quickly. Winter weather is the other problem: low-pressure systems bring long stretches of overcast, and the cold, clear nights between them are the ones to watch.

If you want a proper dark sky, the Eastern Townships to the south-east hold the two best-known sites in the region. A north-facing field, a lakeshore or a cleared ridge beats any city park. From Mount Royal the view of the north is partly blocked by buildings and trees, so it works only as a last-minute option on a major storm night. Check the cloud forecast before you leave; a drive that ends under overcast is the most common way a night ends here.
