There is no removal order that prevents return for a period of three years.
The removal orders would be an exclusion order for overstay, work or study without authorization which would result in a one year ban on return; a two year exclusion order for misrepresentation or a deportation as the result of criminality which results in a lifetime ban on return. Each can be overcome with Minister's consent being obtained prior to the time passing.
Criminality cases require a pardon being granted and is not immigration related, but required in addition to applying for consent to return (ARC - authorization to return to Canada, Minister's Consent).
If you had a conditional discharge the courts may have imposed a period of time set while conditions were imposed, but could not require you to depart Canada unless you were subject to a removal order already and included that you must comply with any other conditions imposed under an act of parliament.
You probably need to fully review what happened in the courts and whether you complied, applied for and were granted a pardon if you did not meet conditions and a conviction resulted.
Nothing prevents you from being sponsored, but if you are found to be inadmissible a refusal will result. To save the cost of fees some review of the specifics of your case should be completed before you start the process.
