On 28 October 1991, the Global Express was unveiled at the NBAA convention.
On 20 December 1993, the programme was launched.
In June 1994, its high-speed configuration was frozen while the low-speed configuration was established in August 1994.
By then, most critical design decisions were taken and almost all suppliers had been selected.
In January 1995, the definition phase was winding down before detailed design.

By June 1995, the backlog was over 40 aircraft, sold out until 2000, leading to Bombardier to expand its early production plans.
At launch, range was extended to 12,000 km (6,500 nmi) to outdo rival Gulfstream.
Bombardier guaranteed the empty weight and range to reply to Gulfstream criticism.
Around 100 sales were needed to cover the development costs.
During October 1995, the first prototype manufacture commenced, the first sections were expected in December at de Havilland's Toronto, while final assembly was to start in March 1996.
By June 1996, the prototype was complete and conducting flight-readiness reviews ahead of its roll-out and first flight.

On 13 October 1996, the first prototype performed its maiden flight from Toronto, one month later than planned, lasting for 2 hours 46 minutes and attaining 11,000 ft (3,350 m) and 210 kn (390 km/h).
The flight test programme used four prototypes, accumulating 2,200 flight hours.
the Bombardier Flight Test Center in Wichita, Kansas was extended by 9,100 m² (100,000 ft²) for the test programme.
On 3 February 1997, the second prototype made its first flight and the third in May 1997.

In late 1995, type certification was forecast for March 1998.
On 31 July 1998, Canadian type certification was granted, European and US approvals followed shortly thereafter.
The first 15 aircraft were to be delivered before January 1999, the Global Express entered service in July 1999.
