Although it is wildly thought that "Canadian" and "English" are the same language, there are some differences in the most basic forms of communication. Here is a guide that will help you understand any foreigners you may come across.
~Words and Definitions~

Dinner - NOUN: The meal between breakfast and supper.
Lunch - ...?
Washroom - NOUN: A place to relieve one's waist, similar to the American "Bathroom".
Phone - VERB: The act of communicating with someone on a telephonic device. "I'll phone you later." Tenses; Phone, Phoning, Phoned.
Call - VERB: The act of visiting or re-visiting someones home. "You can call back next week." Tenses; Call, Calling, Called.
Yous - PRONOUN: The plural form of the word 'You'. "Where are yous headed this evening?"
Eh? - ???: A meaningless statement added to the end of a sentence to either indicate that you are asking a question or that you are waiting for input. A slang form of the word, "Hey?", is comonly used with the younger generation to show their defiance and deviance from their parents. Unfortunately the difference in pronunciation is negligable.
Vowels are: A, E, I, O, U, and sometimes G, Like in Flag, Bag, Tag, and Rag. The G will make the normaly, soft 'a' a hard 'A'.
Foreign words (especially Spanish) are ALWAYS pronounce phonetically. Exp. 'Jealopeno' = 'Ja-la-pen-no', 'Pasta' = 'P-Ah-sta'
As a rule of thumb, the letter 'O' is always pronounce different than the american 'O' in a fetal attempt to further distance themselves from their (American) culture.
