Lytton B.C. sets a new all-time Canadian heat record for the second day in a row Amy Judd It's a record many people likely didn't want to break again. The small community of Lytton B.C. has set a new all-time Canadian heat record for the second day in a row Monday. Environment Canada said Monday this is still a preliminary number as heating may continue for another hour. Less than 24 hours later, Lytton has again broken the all-time Canadian high temperature record by reaching 47.5C at 4pm. This is a preliminary number as heating may continue for another hour. The official summary of all broken records will be posted later! #bcstorm#Lytton
