Calgary, Alberta, Canada, and London, England, are both situated at approximately 51°N latitude. The winter climate in Calgary is much harsher than that experienced in London. Which is the most significant reason the two cities have such different climates?

The major difference here is the availability of water. While London has more waters, it's climate is shaped by the gulf stream helps regulate the ocean temperatures which effectively reduce the severity of the winters and summers. The gulf stream is not available in Calgary hereby making the climate different.
