The city is built mostly on an island surrounded by the St. Lawrence River and the Ottawa River. Both rivers converge at this point making Montreal an important port city. The climate of the region is humid continental meaning the temperature varies but humidity is present.

Overall the Bowen Ratio for Montreal near the North American average at around 0.74. The continentality of Montreal is closer to the interior of North America and by looking at the temperature data the temperature changes are more than one would expect in a maritime region.

Montreal with a high albedo and/or a lower greenhouse value would at that latitude be a much colder region. Potentially freezing the rivers longer having negative effects on the port and regional shipping. Conversely with less albedo and higher greenhouse the port could be open longer and add to the cities ability to transport goods. However warmer conditions could lead to more flooding and severe weather.
