Officials say the second test of Canada's new national public-alert system went better than the initial test six months ago.
Cellphones, televisions and radios across the country buzzed at 1:55pm Wednesday as the Alert Ready system sent test alerts.
Tim Warmington, a spokesman for Public Safety Canada, says the system worked better than the first test in May.
During that test only 60% of wireless users in Manitoba received an alert and in Ontario many wireless subscribers didn't receive any signals. The first test didn't sound at all in Quebec due to a coding error.
Warmington says there is no hard data yet on how many Canadians received the latest alert.
An official with Pelmorex, which runs the National Alert Aggregation and Dissemination system, says the test was a success in every province even though there were some glitches on the East Coast.
Warmington says tests will continue because there is always room for improvement.
