Report
I haven't had the best experience with this firm. Numerous errors on my company's taxes has cost me thousands. Very difficult to get anyone in charge to call me back - maybe they're too busy on the golf course?
Wouldn't recommend.

Report
I have been working with the team at Lumsden for over five years now, and it has been one of the best business decisions I have ever made. They are by definition, a partner and I am honored to have them as part of our team. They have made year-end taxes much more efficient and less of a chore, but their real value is in their understanding of all the complexities of our businesses and how best to use any available incentives to help reduce our fiscal burden.
