According to the link Helsinki is worse in many other areas in November though:

• 40% more cloudy sky
• Less than 50% as much fully clear sky
• More than 100% higher daily chance of precipitation
• About 2.8 times the amount of rainfall (Edit: a lot less snow though)
• 87% as much daylight

Throughout the year Winnipeg may be worse in some aspects than this, but Helsinki is definitely worse in November on many scales.
