Generally, it is feasible to apply for a big sign first and then apply for a small sign after success. Now that you are in Canada, if you submit your online application as soon as possible, the materials will be officially complete by the time you return to China at the end of June (about 40 days). If the process goes smoothly, it should be no problem to get a new visa. If you can't get out when you return home, you can only send the big sign back to China.

(Note: In fact, it is generally recommended to renew the contract about three months before the expiration of the contract, which is safer. It may be a bit hasty to start renewing the contract now. In addition, it is also feasible to return to China with a follow-up visa, but the time is late and the risk of delaying study is greater. This is generally not recommended. )

After returning home, it usually takes about a week to produce results with new big brands and small brands. However, the key to successful renewal depends on your performance during your study in Canada.
