The Canadian Grand Prix is provisionally scheduled to return to the Formula One calendar for next season.
The 2010 dates have been circulated to the teams, with the Montreal event currently set for June 6, although the calendar is not due to be officially confirmed until October.
The Canadian race, along with the British Grand Prix at Donington Park, are still only speculative at present given the doubts that surround them.
Canada missed out this year for financial reasons, and while talks are ongoing with F1 supremo Bernie Ecclestone, there are no guarantees.
The British round currently has a July 11 slot, the same day as the World Cup final. However, it remains unclear whether the track will be ready in time due to ongoing construction.
Silverstone, who seemingly staged their last British race in July, have announced they are ready to step in should Donington Park fail to meet their obligations.
On the 18-race schedule, Bahrain will now host the season opener on March 14, with Australia second on the list for time-zone reasons.
The Melbourne race became a twilight event this year, starting at 5pm local time and 7am in the UK.
With the clocks Down Under and at home changing in late March, the 28th is ideal for broadcasting purposes across Europe.
Other changes see Turkey moved from June to late April; Valencia switched from the searing heat of August to late June, with China now mid-September after being run in April this year.
