在那个担保文件IMM1344E里面，有承诺：
I promise that the sponsored person and his or her family members will not need to apply for
social assistance.
...
然后后面说了即使政府支付了social assistance, 会算你in default. ....
总之，我的理解就是向政府申请的社会救助。
以下不是政府信息，但是可以参考：

Sponsored immigrants and Social assistance
Sponsored immigrants will not be deprived of social assistance because of their sponsored status. According to the present law in Ontario, sponsored immigrants applying for social assistance must continue to seek financial assistance from their sponsor. If they do not seek financial assistance from their sponsor, their social assistance application could be denied. However, if the sponsor is not willing to provide any support, the sponsored immigrant should be entitled to social assistance.
Recovering social assistance payments from the sponsor
If a sponsored immigrant applies for social assistance during the sponsorship period, the Ministry of Community and Social Services (MCSS) will recover the amount paid to the sponsored immigrant as social assistance from the sponsor regardless of the sponsor’s financial situation. MCSS will also notify Canada Immigration of the sponsor’s breach of the sponsorship undertaking so that the sponsor is prevented from sponsorship anyone else until the debt that is owed is repaid.
