Access and arrival
21 km (13 mi) separates Théâtre Lionel-Groulx from Montréal–Trudeau International Airport (YUL) — normal for a city venue, and worth a line in the joining instructions rather than a shuttle contract.
At 4.2 km (2.6 mi) from the city centre it is a short ride from downtown hotels rather than a walk.
Blainville has 4 venues mapped in total and a population of 59,819. The Blainville guide covers the airport, the local time zone and what else is bookable nearby.
The kind of event it takes
811 is enough for a whole programme in a single room, which removes the hardest logistics problem an event has. Ask what the room looks like empty — the seated figure and the usable one are rarely the same.
- award ceremonies
A stage, a bowl of seats and a control room already in place.
- company all-hands
One room, everybody in it, nobody watching on a screen in an overflow space.
