It was a deadly week for Canadians travelling abroad.
A 46-year-old Regina man was murdered in Mexico July 28, according to media reports, while a 26-year-old woman died under mysterious circumstances across the globe in Vietnam on Aug. 2.
The family of Duane Lang confirmed to the CBC he was murdered while vacationing in Puerto Vallarta, Mexico - a popular destination for Canadians and one the insurance broker had visited many times.
More than 100 Canadians never returned after travelling to Mexico during the past five years - and statistics show they are not natural deaths.
In January, Calgary native Sheila Nabb, 37, was severely beaten while on holiday and required extensive facial reconstructive surgery.
Three other Canadians died that month in Mexico - a 35-year-old man was found shot in the head, while on Jan. 4 the bodies of a couple were found bound, stabbed and with signs of torture.
Foreign Affairs warns all Canadians to "exercise a high degree of caution" when travelling to Mexico and even advises to avoid all non-essential travel to the northern states because of high crime rates often linked to drug cartels. Shootouts, kidnappings, assaults and illegal roadblocks can occur at any time, Foreign Affairs warns.
Ian Trites, Foreign Affairs spokesman, said despite the fact "every year there are Canadians who die in Mexico," it remains a top holiday destination with more than 1.5 million travelling there every year.
In Vietnam, Kathy Huynh, 26, died of cardiac arrest after experiencing acute respiratory problems. Local reports cited authorities there claiming it may have been the result of food poisoning.
In the past, the Vietnam food administrator has reported finding high levels of chemicals in some produce imported from China. Vietnamese newspapers have reported on seriously understaffed food inspection centres there.
In June, two sisters from Quebec were found dead in their hotel room on Phi Phi Island in Thailand. Their bodies showed signs of extreme toxic reaction, which local authorities attributed to "serious food poisoning."
Canadian authorities are working with local officials to gather information. Canadians are in charge of neither investigation.
