The IndyCar racer is set to drive the #81 Dodge Charger owned by Canadian Randy MacDonald, in what will be his first race in NASCAR's second-tier series, although not his first stock-car event.
Tagliani has competed for the past three years in the NASCAR Canadian Tire Series, running a limited number of races with one victory to his name, which he claimed last year at Edmonton.
Last weekend, Tagliani competed in the series' race at Trois-Rivieres, where he claimed his first pole position, led 21 of the event's 43 laps, but retired with engine issues.
"Alex has been looking for several months to join the field for our Nationwide Series race, and we are very happy that he has come to an agreement with the Dodge Dealers of Quebec," said Francois Dumontier, promoter of the event.
"He is a resolute and very talented driver, full of enthusiasm, who will give his fans quite a show as he did last weekend in the NASCAR Canadian Tire Series race.
"Canadian fans will have a lot to cheer for with Jacques Villeneuve, Patrick Carpentier, Ron Fellows, and now Alex Tagliani, joining them for a fierce competition on a race track that is quite familiar to this quartet of drivers."
The 36-year-old is running a limited schedule in this year's IndyCar Series with Conquest Racing, with a ninth-place finish at Toronto being his best result thus far.
