Step 1 : Introduction to the question "Canada’s motto “A Mari Usque Ad Mare,” translates to what?"
...This Latin phrase comes from Psalm 72:8 of the Bible. The full line reads, “He shall have dominion also from sea to sea, and from the river unto the ends of the earth." However, “from sea to sea” did not literally apply to Canada until 1871 when British Columbia joined the Dominion, marking Canada’s reach from the Northern Pacific in the west to the Northern Atlantic in the east. It became the country's official motto in 1906.
