Can someone please explain how I have almost $2000 of withheld money from my paycheck? For reference this is a serving job in Ontario and we have recently started to be taxed on our tips. (Thanks Trudeau) TYIA!

Based off the 'YTD' vs 'Period' results, it seems like they seriously underwithheld previously. Assuming this is only for 2 pay periods your previous check would've been gross of 1,614.61 with only 209.84 withheld (~12% rate), so this period is likely just to get back to what your effective rate should truly be (~44%, which seems high, but it's also Canada).

Their system also probably kicked out a much higher withholding rate now since your second gross amount is much larger than your first, thus making the system think your total income throughout the year will be high (right now assuming bi-weekly pay off the latest gross, you would have gross income of $72K).

I would just make sure that through the next few pay periods that the rate eventually levels out around ~30% YTD, otherwise payroll is probably doing something wrong.

Found a decent calculator that shows a decent approximation of total taxes: https://ca.talent.com/tax-calculator/Ontario-72000#:~:text=If%20you%20make%20%2472%2C000%20a,marginal%20tax%20rate%20is%2032.7%25.
