Canadian English names English varieties used in Canada, with variation across regions, communities and speakers. For a scientific account, a pronunciation feature must be operationalized and measured rather than treated as a property shared identically by every speaker. Sociolinguistics and acoustic phonetics provide complementary methods for those comparisons.
An acoustic study by Sky Onosson compared Canadian, American Western and American Northern speech through vowel durations and formant trajectories, examining Canadian raising and the effect of a following consonant's voicing.[ref]

A useful replication would record comparable words and contexts, align vowel intervals, and compare trajectories under a stated time normalization. That separates a pronunciation's changing acoustic shape from differences caused merely by speaking rate or the analysis point. New to topics? Read the docs here!
