I am trying to find the marriage of Marcel John Wilfred Poirier with Ernestine Mireault (when and where).

Marcel John Wilfred Poirier: Born December 25, 1864, Caraquet, New Brunswick

                                        Death: June 26, 1949, Fort William, Ontario

Ernestine Mireault: Born October 5, 1865, St-Alexis-de-Montcalm, Quebec

                            Death: July 28, 1956, Fort William, Ontario

Ernestine's father, Fabien moved to Fort William in 1883. 

 First son born in Fort William  in 1890 (William Henri (Harry) Poirier); all children born in Fort William

They left Fort William in 1915 to homestead in Peace River District, Alberta. Back to Fort William in 1945. 

I could not find anything about their marriage, the place and the date: Probably in Fort William?, maybe in Quebec?  

Thank you for any information on this couple
