El Isimo sezulu futhi i iJografi de Canada babe nomthelela omkhulu uma kukhulunywa nge isiko namasiko abantu baseCanada.
Isimo sezulu se izwe iyahlukahluka: ipholile eningizimu futhi i-arctic enyakatho. Vuliwe ebusikaamagagasi amazinga okushisa ziwela ngaphansi kwezinga-qhwa cishe ezweni lonke. Ngesikhathi sasehlobo, izifundazwe eziseningizimu ngokuvamile zithola amazinga aphezulu omswakama namazinga okushisa angadlula ama-30 degrees Celsius. Izingxenye ezisentshonalanga naseningizimu-mpumalanga yeCanada zithola imvula enkulu, noma kunjalo izindawo ezinotshani omile uma kuqhathaniswa.
Udumo lwaseCanada kuzoba yi- izwe elibandayo. Ngokuqondile, ubusika bungaba nzima kakhulu ezifundeni eziningana zezwe, ngamathuba aphezulu eziphepho ze- iqhwa, izivunguvungu zeqhwa namazinga okushisa angaphansi kuka -50ºC enyakatho. Ezifundeni ezinabantu abaningi, ehlobo zipholile futhi kwesinye isikhathi ziyashisa lapho zifinyelela eziqongweni ezingama-30ºC (imvamisa eMontreal).
E-Vancouver, amazinga okushisa ahlala ezinzile phakathi kuka-5 no-25ºC unyaka wonke. Ngakolunye uhlangothi, ezindaweni ezinjengeKelowna, amazinga okushisa afinyelela ku-40ºC ehlobo, kanti ebusika amazinga okushisa angathinta -15ºC kwesinye isikhathi. Endaweni enabantu abaningi ezweni, isifunda sabakhulu amachibi, amazinga okushisa aphakathi kuka -35ºC no-35ºC.
Ngakolunye uhlangothi, eCanada bekunemicimbi eminingana ephathelene nezinhlekelele zezulu, ezikwazile ukwakha ubuzwe obususelwa ebumbeni nasekuhlonipheni abanye. Njengezibonelo zalezi zinhlekelele singabala isiphepho seqhwa esathi ngo-1998 sahlasela isifundazwe sase Quebec, izikhukhula eManitoba eminyakeni embalwa edlule, nesiphepho esikhulu seqhwa singene Ontario e 1999.
