​Eight works by Group of Seven founding member Lawren Harris are going on the auction block in Toronto tonight.

The 1925 oil canvas Mountains East of Maligne Lake has a pre-sale estimate of $2.5 million to $3.5 million, according to the Heffel Fine Art Auction House.

But Harris paintings have smashed expectations at recent auctions.

It was last November that Mountain Forms by the Brantford, Ont.-born painter went for over $11.2 million, more than double the previous record set in 2002 for the most expensive Canadian work ever sold.

Heading into that auction, Heffel had estimated the 1926 oil canvas could fetch between $3 million and $5 million.

Harris's work got an international boost when American actor-comedian Steve Martin co-curated an exhibit of his paintings, which debuted in 2015 at the Hammer Museum in Los Angeles before heading to the Boston Museum of Fine Arts and Art Gallery of Ontario last year.

Also up for auction tonight are three works by Jean-Paul Riopelle, including Composition, which has a pre-sale estimate of $400,000 to $600,000.

In May, a painting by the Quebec artist sold for more than $7.4 million, good for second on the list of Canada's most expensive works of art. Going into that Heffel sale, the painting Vent du nord had a pre-sale estimate of $1 million to $1.5 million.
