Need investment advice. Buy or hold off ?

hi, I am 41 yrs old. I have invested only ETFs and its grown quite a bit thanks to various world events. Now the qn is i got my bonus recently , like CAD 50k, should i invest now? or hold off as prices are v high? I am 41, so I have at least 20 yrs before I think about retiring. so I am confident in investing more. I was also thinking few things which are pros for putting the money in: Iran war ending will give a boost to the market. SpaceX IPO, Anthropic and Open AI IPOs will give boost as well
