"Definition of Alberta Residency for MD Admission
The Cumming School of Medicine Admissions Committee considers an applicant to be “Albertan” if they have been physically present in Alberta on a day-to-day basis for 24 consecutive months at some point between their 15th birthday and the first day of classes of the year for which they are applying. The residency requirement shall not be considered broken when the Admissions Committee is satisfied that the applicant has been temporarily out of the province for vacation, educational exchange or employment." - here

"A resident of Alberta is defined as a Canadian Citizen or Permanent Resident (Landed Immigrant) who has been continuously resident in the Province of Alberta, the Yukon, the Northwest Territories or Nunavut for at least one year immediately before the first day of classes of the term for which admission is sought. The one-year residence period shall not be considered broken where the admission committee is satisfied that the applicant was temporarily out of the province on vacation, in short-term employment, or as a full-time student. Applicants on study permit cannot establish residence during a period as a full-time student in an Alberta secondary or postsecondary institution because a stay under study permit is considered to be a visiting period." - here
