You’re confusing immigration fraud & tax evasion. They are totally separate.
It would have to be EXTREMELY serious in the tax evasion department to get them deported .
Manipulating their taxes to claim benefits doesn’t fall under that . They’d be subject to interest penalties, deportation , no

He may not really be confused. Tax fraud can result in a criminal conviction. A criminal conviction can result in deportation of a permanent resident by application of s. 64 of the Immigration and Refugee Protection Act I cited above. It can occur at anytime one is living in Canada as a PR. Here's more on the topic:
[60] A permanent resident will be rendered inadmissible for serious criminality in circumstances set out in s. 36(1)(a) of the
Immigration and Refugee Protection Act, S.C. 2001, c. 27 [
IRPA]:
36(1) A permanent resident or foreign national is inadmissible on grounds of serious criminality for
(a) Having been convicted in Canada of an offence under and Act of Parliament punishable by a maximum term of imprisonment of at least 10 years, or of an offence under an Act of Parliament for which a term of imprisonment of more than six months has been imposed.
[61] Sexual assault carries a maximum penalty of 10 years or more, and having entered guilty pleas to two counts of sexual assault, Mr. Ramzan is inadmissible to Canada on the basis of serious criminality and subject to a removal order. The Immigration Appeal Division of the Immigration and Refugee Board has the power to stay a removal order on humanitarian and compassionate grounds.
[62] The availability of an appeal to the Immigration Appeal Division is dictated by the length of imprisonment imposed. An effective term of imprisonment of more than six months would render Mr. Ramzan inadmissible for serious criminality and he would lose his right of appeal and be placed at substantial risk of being deported to his country of origin. A CSO is not considered a term of imprisonment for the purposes of s. 36(1)(a) of the
IRPA and would not lead to inadmissibility or a loss of appeal rights:
Tran v. Canada (Public Safety and Emergency Preparedness), 2017 SCC 50.
[63] Mr. Ramzan’s eligibility for citizenship would also be impacted by a sentence of imprisonment of more than six months. A person is not eligible to be granted citizenship or take the oath of citizenship while subject to a removal order, serving a term of imprisonment, being on parole or under a probation order and is not eligible to apply for citizenship for four years following a conviction for an indictable offence. Time in custody, on parole or probation does not count as presence in Canada for the purposes of residency requirements under the
Citizenship Act, R.S.C. 1985, c. C-29.
