Glasgow Warriors will play Canada and Top 14 giants Clermont in warm-up games to prepare for the new season.
The PRO12 champions will begin a week-long training camp in France on Saturday 8 August, which will conclude with a game against Top 14 side Clermont Auvergne on Friday 14 August (kick-off 8pm local time).
The match with the European Rugby Champions Cup runners-up will be played in Issoire, which is located 25 miles south of Clermont-Ferrand on the Couze River and the game will be the showpiece event at the 2015 Auvergne Challenge.
Clermont reached the final of both the European Rugby Champions Cup and Top 14, before losing out to Toulon and Stade Francais respectively last season.
The squad will then return to Glasgow for a week of training, which will culminate in an open training session at Scotstoun from 4pm until 6pm on Friday 21 August.
The Warriors squad will then fly to Nova Scotia on Tuesday 25 August and will play Canada in Halifax on Saturday 29 August (kick-off 3pm local time) in a game being billed as 'The Battle for New Scotland'.
Canada, who currently sit 18th in the world rankings, will play France, Ireland, Italy and Romania in Pool D at the Rugby World Cup.
Three former Glasgow players could feature for Canada, with DTH van der Merwe, Connor Braid and Taylor Paris all in contention, while current Canada scrum-half Gordon McRorie was born in Scotland.
Glasgow Warriors head coach Gregor Townsend told the Warriors website: "Clermont will provide the ideal test for us ahead of the new season.
"They have performed consistently well at the highest level of European rugby over a number of years and it'll be a good challenge for our players.
"We're also really looking forward to traveling to Nova Scotia to play Canada in Halifax, as they continue their preparations for the Rugby World Cup.
"The opposition could have a very familiar look if DTH (van der Merwe), Connor (Braid) and Taylor (Paris) are included in the Canada team, and it'll be great to catch up with them while we're out there.
"It's an excellent opportunity to play a top class international side, while also promoting the Glasgow Warriors brand internationally and giving our supporters in Canada the chance to support the team."
