Pierre Gasly took another pole with team-mate Antonio Giovinazzi in a close second to continue the dominant form of the Prema team.
However, due to irregularities in the tyre pressures, Giovinazzi was demoted toward the end of the grid, elevating third place Artem Markelov to the front row.
The pair were racing side-by-side and after barely leaving enough space through the corner, Pic lost control through the corner and counter-steered straight into Canamasas' rear wheel, sending him into a roll.
The safety car put Gasly from a comfortable first to fourth and now behind drivers on brand-new tyres.
As well as this, Luca Ghiotto achieved the fastest lap, completing a successful race for the Italians on home soil.
