Officials at Vancouver International Airport say they are working with police, Canadian Border Services Agency staff and others to ensure a heightened level of security today.  

Vice-president of operations Steve Hankinson said Tuesday people will notice more police officers and dog teams at the airport, but he wouldn't go into further detail.

"Beyond that for obvious reasons we don't disclose the details of our security practices but it's multi-layered and we have a comprehensive program to ensure everyone is safe and secure at YVR."

Hankinson confirmed as at 10 a.m. PT there are no delays or cancellations at Vancouver International Airport following Tuesday morning's deadly bombings in Brussels that killed at least 34 people.

He said none of their flights to Europe are affected, and they don't have any direct flights to Belgium.

Nevertheless anyone travelling to Europe in the next few days should be prepared for widespread travel disruptions and heightened security that may cause delays.

Vancouver police and the Transit Police are also stepping up security by increasing police presence throughout the city.

No Canadian causalities reported

Authorities locked down the Belgian capital on Tuesday after explosions rocked the Brussels airport and subway system. Belgium raised its terror alert to its highest level, diverting arriving planes and trains and ordering people to stay where they were. Airports across Europe tightened security.

At least 14 people were killed and 81 injured in twin explosions at the Zaventem Airport near Brussels. A Brussels subway spokesman says 20 people were killed and 55 injured in an explosion at the Maelbeek train station
