A privately-owned collection of Canadian masterpieces is up for auction in December, with paintings by Emily Carr, Paul Kane and Tom Thomson among the highlights.

The 50 paintings have an estimated value of $8 to $12 million and are part of a larger collection of 150 artworks with an estimated value of more than $20 million. It’s considered one of the largest private collections in Canada of its size.

"This collection of artwork, which was so carefully collected and so passionately collected, every artwork is incredible," Rob Cowley, art specialist and president at Cowley Abbott Auctions, told CTV's Your Morning on Monday.

"The market for these artists is quite lucrative leading to very high auction estimates and lots of demand," he said. "Subject matter is very important, so what an artist is best known for, the period of the work, each of these are from exquisite periods…The condition, the quality of the work…"

The art belonged to Toronto-based collectors and has been curated for over 60 years. Many paintings have been loaned to art galleries, museums and international art shows.
