How It Helps Your Business English

What this resource offers:

The guide compares Canadian and American English in four areas: spelling, vocabulary, date formats and units of measurement, with examples of each. It then explains why a document prepared for a Canadian institution is expected to follow Canadian conventions, and what that means for translated material submitted to official bodies.

How to use this resource:

You can use this when a document has to be accepted by a Canadian organisation. Check your spelling, vocabulary, dates and measurements against the four sections, since those are the details a reader notices first. The closing part is worth reading if you ever submit translated documents, because it explains which conventions an official body expects to see.
