During an eruption, if the wind is from the east at 10,000 feet (outflow), the tephra will fall on Vancouver, Canada in about an hour.

I am the Man From Minto© ™ ® - A Prospector Who Knows His Rocks And Stuff© ™ ® The 2010 Mount Meager landslide was a large catastrophic debris avalanche that flowed to the south, into the Lillooet Valley British Columbia, Canada, on August 6 at 3:27 a.m. PDT (UTC-7). More than 45,000,000 m3 (1.6×109 cu ft) of debris slid down Mount Meager, temporarily blocking Meager Creek and destroying local bridges, roads and equipment. It was one of the largest landslides in Canadian history and one of over 20 landslides to have occurred from the Mount Meager massif in the last 10,000 years. Although voluminous, there were no fatalities caused by the event due in part to its remote and uninhabited location. The landslide was large enough to send seismic waves more than 2,000 km (1,200 mi) away into the neighboring U.S. states of Alaska and Washington and beyond. Multiple factors led to the slide: Mount Meager's weak slopes have left it in a constant state of instability. The massif has been a source of large volcanic debris flows for the last 8,000 years, many of which have reached several tens of kilometres downstream in the Lillooet River valley., to the south. It is arguably the most unstable mountain massif in Canada and may also be its most active landslide area. And on the north side lies Downton Lake Hydro Reservoir, impounded by the La Joi Dam, the uppermost of the Bridge River Project dams. The earliest identified Holocene landslide was in 7900 BP (before the present, or read it as the number of years ago). Further landslides occurred in 6250 BP, 5250 BP, 4400 BP, 2600 BP, 2400 BP, 2240. BP BP, 2170 BP, 1920 BP, 1860 BP, 870 BP, 800 BP, 630 BP, 370 BP, 210 BP, 150 BP and in 1931, 1947, 1972, 1975, 1984, 1986 and 1998. These events were attributed to structurally weak volcanic rocks, glacial unloading, recent explosive volcanism and glacial activity. Those who dance with earthquakes and volcanoes are considered mad by those who cannot smell the sulfur.

M9+ - M10+ Cascadia Fault Megaquake and Tsunami Preparedness in British Columbiauake Earthquake and Tsunami Preparedness in British Columbia

There are, basically, no courses in British Columbia to prepare for a really,really BIG ONE, an M9+ or even an M10+.  There seems to be little, or no, preparation on the part of government or other civil authority to respond to that eventuality.
 
At about 21:00 (9PM) on January 26, 1700 the last 1700 Cascadia earthquake occurred along the Cascadia subduction zone (Fault) ~ with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate that underlies the Pacific Ocean, from mid-Vancouver Island in British Columbia, Canada, south along the Pacific Northwest coast as far as northern California. The length of the fault rupture was about 1,000 kilometers (620 miles) with an average slip of 20 meters (66 ft).
The earthquake caused a tsunami that struck the coast of Japan and British Columbia, Washington, Oregon and Northern California, overwhelming many coastal Japanese and North American First Nation communities.

Yet, even now we are running simulations for a magnitude 8.5-megathrust earthquake.

Courses are available from The Justice Institute of British Columbia:



Prerequisite: Introduction to Emergency Management in Canada – EM110 http://www.jibc.ca/course/em110 This seven-hour self-paced course is available part-time online or by correspondence, and includes an exam. - $49.88 (February, 2015). Note that additional fees and taxes may apply in addition to listed tuition price. Tuition listed above is for Canadian students and permanent residents.
