Businessmen don’t get to write off their living expenses either, but feasibly you could start a business and become a contractor for your employer so you could write off things like footwear, home office square footage, and a standard deduction per mil driven between two work locations.

Best part is the IRS will never audit you unless they have the staff and they can get more out of you than the cost of the audit (roughly 20k minimum).

home office square footage

Can you not do that as an employee in Canada?

In Australia employees who work from home can either calculate all your actual work from home expenses and deduct that, or use the standard fixed rate (which varies by year, but last financial year was 70 c per hour) which includes utilities and stationary/consumables. With the fixed rate you can still additionally deduct depreciating assets like computers and furniture (proportional to how often they are actually used for work).
