what year did Canada convert?

Technically, you're both wrong.

But you're almost right:

From Wikipedia:

"The Liberal federal government of Pierre Trudeau first began implementing metrication in Canada in 1970 with a government agency dedicated to implementing the project, the Metric Commission, being established in 1971."

From the CBC's Digital Archives:

"Canada's decision to go metric in 1970 definitely sparked some passionate debates."

From The Canadian Encyclopedia:

"In January 1970 the White Paper on Metric Conversion in Canada set out Canadian government policy. It stated that a single, coherent measurement system based on metric units should be used for all measurement purposes, including legislation."

It is a gradual conversion and it is not over yet. I still see food sold by the pound.

Bolts, piping and other hardware are generally in the Imperial system. Steel beams, etc are Imperial and sold by the pound.

Look regardless nothing happened in the 70`s because everyone was still ****** up from the 60`s

We certainly learned it in school by the mid 1970's.

if you check this link it says in 1970. http://wiki.answers.com/Q/What_year_did_Canada_con...
