About Us

We focus on the finances, so you can focus on your craft

Leadership Team


Mike Widdis, ICIA, CPB   

Founder, Corporate Tax, Co-Chair for IPBC Cambridge

“The sun doesn’t give light to the moon assuming the moon is going to owe it one.”

Mike loves planning and helping people, period!

Oh, and he’s a “Tax Nerd” and we’re not afraid to flaunt it. Tax planning and execution make him tick, but we are guessing it is not your thing. Mike wants it to be his thing – for you.

At UpSide Accounting we love creative people, but definitely not “creative accounting”. When you stay on the right side of the law it’s called tax planning. Tax planning minimizes your corporate & sales tax burdens but keeps you in the “good books” with the CRA.

We want you to spend your valuable time creatively running your business. Let Mike spend his getting your taxes planned and filed on time.
