Does Canadian English have regional differences?

American English has many regional variations in terms of accent.
Californian accent is different from New York accent.
They have Southern accent(very unique), Midwestern accent, New England accent and etc.

Does Canadian English have regional differences as well?
If so, what are the noticeable Canadian accents?

I've never heard a Newfoundland accent, but I'd like to. Does it sound quite similar to Hiberno-English?

Wow, that is an interesting accent. :)

>>Almost all the English-speaking settlers to the West were from Ontario, so the accent from Ontario westward is almost uniform.<<

It should also be noted that Ontario had significant settlement from the inland portions of the Northeast of what is now the US, due to United Empire Loyalists fleeing what became the US. Similarly, dialects in the interior of the Northeast of the US are also what Northern and North Central dialects in the US are descended from and, with contact with Western dialects, what most modern California and Pacific Northwest dialects are descended from. This is why Canadian English seems so standard, because it is closely genetically related to Northern dialects in the US, and Canadian dialects in Ontario have remained in close contact with Northern dialects in the US while more western Canadian dialects have had close contact with Western dialects in the US.

Atlantic Canada is less prone to the CVS (Canadian vowel shift),
Pacific Canada is less prone to CR (Canadian raising).

Manitoba is the province with the strongest CVS (father, John, lot have /Q/ vowel) while Atlantic Canada has the strongest (most frequent, that is) CR.
