Which time zone would you travel through going from west to east in Canada?

When traveling from west to east across Canada, you would encounter several time zones sequentially. The correct answer is Mountain Standard Time, as this zone is part of the transition you would experience when moving eastward from the Pacific Time Zone (PST) and before reaching Central Standard Time.

In Canada, the time zones are set from west to east. Starting from the Pacific Time Zone, you would first move into Mountain Standard Time, then into Central Standard Time, followed by Eastern Standard Time, and so forth.

Mountain Standard Time is pivotal in this journey as it serves as a bridge between the Pacific Time Zone and the further eastern time zones. The other options, while they are legitimate time zones in Canada, do not accurately represent the correct progression when traveling specifically from west to east. For instance, Newfoundland Standard Time, while it is indeed an actual time zone, is situated on the easternmost side of the country. Central Standard Time comes after Mountain Standard Time in the chronological sequence, and Pacific Standard Time is the starting point of the journey heading eastward.
