Details of the thefts have been under wraps pending a police investigation, with specialist fine art loss adjuster Mark Dalrymple of Tyler & Co confirming that video surveillance footage "clearly shows the perpetrator carrying out the theft".
The suspect is a 5ft 8in tall white man in his mid 30s carrying a satchel. An additional reward of up to Can$10,000 is on offer for his identification.
Clare Dewey, AXA Art's claims manager said: "The objects are easily portable and may have been sent outside Quebec. The priority is for everyone - AXA Art, the police and the museum team - to work in close collaboration in order to recover these objects."
